Chord

Chord(data, source=None, target=None, value=None, square_matrix=False, label=None, xgrid=False, ygrid=False, **kw)

Create a chord chart using ChordBuilder to render a chord graph from a variety of value forms. This chart displays the inter-relationships between data in a matrix.

The data can be generated by the chart interface. Given a DataFrame, select two columns to be used as arcs with source and target attributes, passing by the name of those columns. The Chord chart will then deduce the relationship between the arcs.

The value of the connections can be inferred automatically by counting source and target. If you prefer you can assign a fixed value for all the connections with value simply passing by a number. A third option is to pass a reference to a third column in the DataFrame with the values for the connections.

If you want to plot the relationships in a squared matrix, simply pass the matrix and set square_matrix attribute to True.

Reference: Chord diagram on Wikipedia

Parameters:
  • data (Accepted Charts Data Formats) – the data source for the chart.
  • source (list(str) – Data source to use as origin of the connection to a destination.
  • target (list(str) – Data source to use as destination of a connection.
  • value (list(num) – The value the connection should have.
  • square_matrix (bool, optional) – If square matrix, avoid any calculations during the setup.
  • label (list(str) – The labels to be put in the areas.
Returns:

Uses the HeatMapBuilder to render the geometry from values.

A HeatMap is a 3 Dimensional chart that crosses two dimensions, then aggregates values that correspond to the intersection of the horizontal and vertical dimensions. The value that falls at the intersection is then mapped to a color in a palette by default. All values that map to the positions on the chart are binned by the number of discrete colors in the palette.

  • x (str or list(str) – specifies variable(s) to use for x axis
  • y (str or list(str) – specifies variable(s) to use for y axis
  • values (str, optional) – the values to use for producing the histogram using table-like input data
  • stat (str, optional) – the aggregation to use. Defaults to count. If provided None, then no aggregation will be attempted. This is useful for cases when the values have already been aggregated.
  • hover_tool (bool, optional) – whether to show the hover tool. Defaults to True
  • hover_text (str, optional) – a string to place beside the value in the hover tooltip. Defaults to None. When None, a hover_text will be derived from the aggregation and the values column.

Line

Line(data=None, x=None, y=None, **kws)

Create a line chart using LineBuilder to render the glyphs.

The line chart is typically is used with column oriented data, where each column contains comparable measurements and the column names are treated as a categorical variable for differentiating the measurement values. One of the columns can be used as an index for either the x or y axis.

Note

Only the x or y axis can display multiple variables, while the other is used as an index.

Parameters:
  • data (list(list) – a 2d data source with columns of data for each line.
  • x (str or list(str) – specifies variable(s) to use for x axis
  • y (str or list(str) – specifies variable(s) to use for y axis

In addition to the parameters specific to this chart, Chart Defaults are also accepted as keyword parameters.

Note

This chart type differs on input types as compared to other charts, due to the way that line charts typically are plotting labeled series. For example, a column for AAPL stock prices over time. Another way this could be plotted is to have a DataFrame with a column of stock_label and columns of price, which is the stacked format. Both should be supported, but the former is the expected one. Internally, the latter format is being derived.

Returns:includes glyph renderers that generate the lines
Return type:Chart

Examples:

import numpy as np
from bokeh.charts import Line, output_file, show

# (dict, OrderedDict, lists, arrays and DataFrames are valid inputs)
xyvalues = np.array([[2, 3, 7, 5, 26], [12, 33, 47, 15, 126], [22, 43, 10, 25, 26]])

In addition to the parameters specific to this chart, Chart Defaults are also accepted as keyword parameters.

Returns:includes glyph renderers that generate the scatter points
Return type:Chart

Examples:

from bokeh.sampledata.autompg import autompg as df
from bokeh.charts import Scatter, output_file, show

                  title="Auto MPG", xlabel="Miles Per Gallon",
                  ylabel="Horsepower")

output_file('scatter.html')
show(scatter)

Step

Step(data=None, x=None, y=None, **kws)

Create a step chart using StepBuilder to render the geometry from the inputs.

Note

Only the x or y axis can display multiple variables, while the other is used as an index.

Parameters:
  • data (list(list) – a 2d data source with columns of data for each stepped line.
  • x (str or list(str) – specifies variable(s) to use for x axis
  • y (str or list(str) – specifies variable(s) to use for y axis

In addition to the parameters specific to this chart, Chart Defaults are also accepted as keyword parameters.

Note

This chart type differs on input types as compared to other charts, due to the way that series-type charts typically are plotting labeled series. For example, a column for AAPL stock prices over time. Another way this could be plotted is to have a DataFrame with a column of stock_label and columns of price, which is the stacked format. Both should be supported, but the former is the expected one. Internally, the latter format is being derived.

Builders

class AreaBuilder(*args, **kws)

This is the Area builder and it is in charge of generating glyph renderers that together produce an area chart.

Essentially, we provide a way to ingest the data, make the proper calculations and push the references into a source object. We additionally make calculations for the ranges. And finally add the needed glyphs (markers) taking the references from the source.

glyph

alias of AreaGlyph

class BarBuilder(*args, **kws)

This is the Bar builder and it is in charge of plotting Bar chart (grouped and stacked) in an easy and intuitive way.

Essentially, it utilizes a standardized way to ingest the data, make the proper calculations and generate renderers. The renderers reference the transformed data, which represent the groups of data that were derived from the inputs. We additionally make calculations for the ranges.

The x_range is categorical, and is made either from the label argument or from the pandas.DataFrame.index. The y_range can be supplied as the parameter continuous_range, or will be calculated as a linear range (Range1d) based on the supplied values.

The bar builder is and can be further used as a base class for other builders that might also be performing some aggregation across derived groups of data.

class Builder(*args, **kws)

A prototype class to inherit each new chart Builder type.

It provides useful methods to be used by the inherited builder classes, in order to automate most of the charts creation tasks and leave the core customization to specialized builder classes. In that pattern inherited builders just need to provide the following methods:

Required:

  • yield_renderers(): yields the glyphs to be rendered into the plot. Here you should call the add_glyph() method so that the builder can setup the legend for you.
  • set_ranges(): setup the ranges for the glyphs. This is called after glyph creation, so you are able to inspect the comp_glyphs for their minimum and maximum values. See the create() method for more information on when this is called and how the builder provides the ranges to the containing Chart using the Chart.add_ranges() method.

Optional:

  • setup(): provides an area where subclasses of builder can introspect properties, setup attributes, or change property values. This is called before process_data().
  • process_data(): provides an area where subclasses of builder can manipulate the source data before renderers are created.
__init__(*args, **kws)

Common arguments to be used by all the inherited classes.

Parameters:
  • data (Accepted Charts Data Formats) – source data for the chart
  • legend (str, bool) – the legend of your plot. The legend content is inferred from incoming input.It can be top_left, top_right, bottom_left, bottom_right. It is top_right is you set it as True.
source

obj – datasource object for your plot, initialized as a dummy None.

x_range

obj – x-associated datarange object for you plot, initialized as a dummy None.

y_range

obj – y-associated datarange object for you plot, initialized as a dummy None.

groups

list – to be filled with the incoming groups of data. Useful for legend construction.

data

dict – to be filled with the incoming data and be passed to the ChartDataSource for each Builder class.

attr

list(AttrSpec – to be filled with the new attributes created after loading the data dict.

column_selector

alias of OrderedAssigner

add_glyph(group, glyph)

Add a composite glyph.

Manages the legend, since the builder might not want all attribute types used for the legend.

Parameters:
  • group (DataGroup) – the data the glyph is associated with
  • glyph (CompositeGlyph) – the glyph associated with the group
Returns:

None

collect_attr_kwargs()
create(chart=None)

Builds the renderers, adding them and other components to the chart.

Parameters:chart (Chart, optional) – the chart that will contain the glyph renderers that the Builder produces.
Returns:Chart
classmethod generate_help()
get_dim_extents()

Helper method to retrieve maximum extents of all the renderers.

Returns:a dict mapping between dimension and value for x_max, y_max, x_min, y_min
get_group_kwargs(group, attrs)
process_data()

Make any global data manipulations before grouping.

It has to be implemented by any of the inherited class representing each different chart type. It is the place where we make specific calculations for each chart.

Returns:None
set_ranges()

Calculate and set the x and y ranges.

It has to be implemented by any of the subclasses of builder representing each different chart type, and is called after yield_renderers().

Returns:None
setup()

Perform any initial pre-processing, attribute config.

Returns:None
yield_renderers()

Generator that yields the glyphs to be draw on the plot

It has to be implemented by any of the inherited class representing each different chart type.

Yields:GlyphRenderer
attribute_columns

property type: attribute_columns:List(Column Name or Column String)

All columns used for specifying attributes for the Chart. The Builder will set this value on creation so that the subclasses can know the distinct set of columns that are being used to assign attributes.

attributes

property type: attributes:Dict(String, Instance(AttrSpec))

The attribute specs used to group data. This is a mapping between the role of the attribute spec (e.g. ‘color’) and the AttrSpec class (e.g., ColorAttr). The Builder will use this attributes property during runtime, which will consist of any attribute specs that are passed into the chart creation function (e.g., Bar), ones that are created for the user from simple input types (e.g. Bar(..., color=’red’) or Bar(..., color=<column_name>)), or lastly, the attribute spec found in the default_attributes configured for the subclass of Builder.

comp_glyph_types

property type: comp_glyph_types:List(Instance(CompositeGlyph))

comp_glyphs

property type: comp_glyphs:List(Instance(CompositeGlyph))

A list of composite glyphs, where each represents a unique subset of data. The composite glyph is a helper class that encapsulates all low level Glyph, that represent a higher level group of data. For example, the BoxGlyph is a single class that yields each GlyphRenderer needed to produce a Box on a BoxPlot. The single Box represents a full array of values that are aggregated, and is made up of multiple Rect and Segment glyphs.

default_attributes = None
dimensions = None

The dimension labels that must exist to produce the glyphs. This specifies what are the valid configurations for the chart, with the option of specifying the type of the columns. The ChartDataSource will inspect this property of your subclass of Builder and use this to fill in any required dimensions if no keyword arguments are used.

label_attributes = []

Used to assign columns to dimensions when no selections have been provided. The default behavior is provided by the OrderedAssigner, which assigns a single column to each dimension available in the Builder‘s dims property.

labels

property type: labels:List(String)

Represents the unique labels to be used for legends.

legend_sort_direction

property type: legend_sort_direction:Enum(‘ascending’, ‘descending’)

Sort direction to apply to sort_legend. Valid values are: ascending or descending.

legend_sort_field

property type: legend_sort_field:String

Attribute that should be used to sort the legend, for example: color, dash, maker, etc. Valid values for this property depend on the type of chart.

Optional input to override the default palette used
by any color attribute.
req_dimensions = []
sort_dim

property type: sort_dim:Dict(String, Bool)

property type: x_range:Instance(Range)

xlabel

property type: xlabel:String

xscale

property type: xscale:String

y_range

  • required_dims (List(List(Str) – list of list of valid dimensional selections for the chart.
  • selections (Dict(dimension, List(Column) – mapping between a dimension and the column name(s) associated with it. This represents what the user selected for the current chart.
  • column_assigner (ColumnAssigner, optional) – a reference to a ColumnAssigner class, which is used to collect dimension column assignment when keyword arguments aren’t provided.

Attempt to add special case columns to the DataFrame for the builder.

stack_measures(measures, ids=None, var_name='variable', value_name='value')

De-pivots _data from a ‘wide’ to ‘tall’ layout.

A wide table is one where the column names represent a categorical variable and each contains only the values associated with each unique value of the categorical variable.

This method uses the pandas.melt() function with additional logic to make sure that the same data source can have multiple operations applied, and so all other columns are maintained through the stacking process.

Example

Note

This example is fairly low level and is not something the typical user should worry about. The interface for data transformations from the user perspective are the Chart Functions.

>>> data = {'a': [1, 2, 3, 4],
...         'b': [2, 3, 4, 5],
...         'month': ['jan', 'jan', 'feb', 'feb']
...         }
>>> ds = ChartDataSource.from_data(data)
>>> ds['x'] =['a', 'b'] # say we selected a and b for dimension x

We may want to combine ‘a’ and ‘b’ together. The final data would look like the following:

>>> ds.stack_measures(['c', 'd'], var_name='c_d_variable',
...                   value_name='c_d_value')
>>> ds.df
Out[35]:
      month a_b_variable  a_b_value
    0   jan            a          1
    1   jan            a          2
    2   feb            a          3
    3   feb            a          4
    4   jan            b          2
    5   jan            b          3
    6   feb            b          4
    7   feb            b          5

The transformed data will use the var_name and value_name inputs to name the columns. These derived columns can then be used as a single column to reference the values and the labels of the data. In the example, I could plot a_b_value vs month, and color by a_b_variable.

What this does for you over the pandas.melt() method is that it will apply the DataOperator for a dimension if it exists (e.g. Blend, generated by blend()), and it will try to handle the id columns for you so you don’t lose other columns with the melt transformation.

Returns:None
attr_specs
columns

All column names associated with the data.

Returns:List(Str)
df
index

The index for the pandas.DataFrame data source.

source

The DataGroup contains a map from the labels of each attribute associated with an AttrSpec to the value of the attribute assigned to the DataGroup.

__init__(label, data, attr_specs)

Create a DataGroup for the data, with a label and associated attributes.

Parameters:
  • label (str) – the label for the group based on unique values of each column
  • data (pandas.DataFrame) – the subset of data associated with the group
  • dict (attr_specs) – mapping between attribute name and the associated AttrSpec.
get_values(selection)

Get the data associated with the selection of columns.

Parameters:selection (List(Str) – the column or columns selected
Returns:pandas.DataFrame
to_dict()
attributes
source

The ColumnDataSource representation of the DataFrame.

class CompositeGlyph(**properties)

Represents a subset of data.

A collection of hetero or homogeneous glyph renderers which represent a subset of data. The purpose of the composite glyph is to abstract away the details of constructing glyphs, based on the details of a subset of data, from the grouping operations that a generalized builders must implement.

In general, the Builder operates at the full column oriented data source level, segmenting and assigning attributes from a large selection, while the composite glyphs will typically be passed an array-like structures with one or more singular attributes to apply.

Another way to explain the concept is that the Builder operates as the groupby, as in pandas, while the CompositeGlyph operates as the function used in the apply.

What is the responsibility of the Composite Glyph?
  • Produce GlyphRenderers

  • Apply any aggregations

  • Tag the GlyphRenderers with the group label

  • Apply transforms due to chart operations
    • Note: Operations require implementation of special methods

Attribute Specs

class AttrSpec(columns=None, df=None, iterable=None, default=None, items=None, **properties)

A container for assigning attributes to values and retrieving them as needed.

A special function this provides is automatically handling cases where the provided iterator is too short compared to the distinct values provided.

Once created as attr_spec, you can do attr_spec[data_label], where data_label must be a one dimensional tuple of values, representing the unique group in the data.

See the AttrSpec.setup() method for the primary way to provide an existing AttrSpec with data and column values and update all derived property values.

__init__(columns=None, df=None, iterable=None, default=None, items=None, **properties)

Create a lazy evaluated attribute specification.

Parameters:
  • columns – a list of column labels
  • df (DataFrame) – the data source for the attribute spec.
  • iterable – an iterable of distinct attribute values
  • default – a value to use as the default attribute when no columns are passed
  • items – the distinct values in columns. If items is provided as input, then the values provided are used instead of being calculated. This can be used to force a specific order for assignment.
  • **properties – other properties to pass to parent HasProps
set_columns(columns)

Set columns property and update derived properties as needed.

setup(data=None, columns=None)

Set the data and update derived properties as needed.

attrname

property type: attrname:String

Name of the attribute the spec provides.

bins

property type: bins:Instance(Bins)

If an attribute spec is binning data, so that we can map one value in the iterable to one value in items, then this attribute will contain an instance of the Bins stat. This is used to create unique labels for each bin, which is then used for items instead of the actual unique values in columns.

columns

property type: columns:Either(Column Name or Column String, List(Column Name or Column String))

The label or list of column labels that correspond to the columns that will be used to find all distinct values (single column) or combination of values ( multiple columns) to then assign a unique attribute to. If not enough unique attribute values are found, then the attribute values will be cycled.

data

property type: data:Instance(ColumnDataSource)

default

property type: default:Any

The default value for the attribute, which is used if no column is assigned to the attribute for plotting. If the default value is not provided, the first value in the iterable property is used.

property type: items:Any

The attribute specification calculates this list of distinct values that are found in columns of data.

iterable

property type: iterable:List(Any)

series
sort

property type: sort:Bool

A boolean flag to tell the attribute specification to sort items, when it is calculated. This affects which value of iterable is assigned to each distinct value in items.

class ColorAttr(**kwargs)

Note

this is a special attribute specification, which is used for defining which labels are used for one aspect of a chart (grouping) vs another (stacking or legend)

get_levels(columns)

Provides a list of levels the attribute represents.

Utilities

df_from_json(data, rename=True, **kwargs)

Attempt to produce pandas.DataFrame from hierarchical json-like data.

This utility wraps the pandas.io.json.json_normalize() function and by default will try to rename the columns produced by it.

Parameters:
  • data (str or list(dict) – a path to json data or loaded json data. This function will look into the data and try to parse it correctly based on common structures of json data.
  • (bool, optional (rename) – try to rename column hierarchy to the base name. So medals.bronze would end up being bronze. This will only rename to the base column name if the name is unique, and only if the pandas json parser produced columns that have a ‘.’ in the column name.
  • **kwargs – any kwarg supported by pandas.io.json.json_normalize()
Returns:

a parsed pandas dataframe from the json data, unless the path does not exist,

the input data is nether a list or dict. In that case, it will return None.
