bokeh.models.tools

Bokeh comes with a number of interactive tools.

There are five types of tool interactions:

  • Pan/Drag
  • Click/Tap
  • Scroll/Pinch
  • Actions
  • Inspectors

For the first three comprise the category of gesture tools, and only one tool for each gesture can be active at any given time. The active tool is indicated on the toolbar by a highlight next to to the tool. Actions are immediate or modal operations that are only activated when their button in the toolbar is pressed. Inspectors are passive tools that merely report information or annotate the plot in some way, and may always be active regardless of what other tools are currently active.

property type: Enum ( Dimensions )

Which dimensions the box selection is to be free in. By default, users may freely draw selections boxes with any dimensions. If only “width” is supplied, the box will be constrained to span the entire vertical space of the plot, only the horizontal dimension can be controlled. If only “height” is supplied, the box will be constrained to span the entire horizontal space of the plot, and the vertical dimension can be controlled.

property type: List ( String )

A list of names to query for. If set, only renderers that have a matching value for their name attribute will be used.

overlay

property type: Instance ( BoxAnnotation )

If only “width” is supplied, the box will be constrained to span the entire vertical space of the plot, only the horizontal dimension can be controlled. If only “height” is supplied, the box will be constrained to span the entire horizontal space of the plot, and the vertical dimension can be controlled.

class CrosshairTool(**kwargs)[source]

Bases: bokeh.models.tools.Inspection

toolbar icon: crosshair_icon

The crosshair tool is a passive inspector tool. It is generally on at all times, but can be configured in the inspector’s menu associated with the toolbar icon shown above.

The crosshair tool draws a crosshair annotation over the plot, centered on the current mouse position. The crosshair tool may be configured to draw across only one dimension by setting the dimension property to only width or height.

dimensions

property type: Enum ( Dimensions )

class HelpTool(**kwargs)[source]

Bases: bokeh.models.tools.Action

The help tool is a widget designed to replace the hardcoded ‘Help’ link. The hover text can be customized through the help_tooltip attribute and the redirect site overridden as well.

help_tooltip

property type: String

Tooltip displayed when hovering over the help icon.

redirect

property type: String

Site to be redirected through upon click.

class HoverTool(**kwargs)[source]

Bases: bokeh.models.tools.Inspection

toolbar icon: crosshair_icon

The hover tool is a passive inspector tool. It is generally on at all times, but can be configured in the inspector’s menu associated with the toolbar icon shown above.

By default, the hover tool displays informational tooltips whenever the cursor is directly over a glyph. The data to show comes from the glyph’s data source, and what is to be displayed is configurable with the tooltips attribute that maps display names to columns in the data source, or to special known variables.

Here is an example of how to configure and use the hover tool:

# Add tooltip (name, field) pairs to the tool. See below for a
# description of possible field values.
hover.tooltips = [
    ("index", "$index"),
    ("(x,y)", "($x, $y)"),
    ("radius", "@radius"),
    ("fill color", "$color[hex, swatch]:fill_color"),
    ("foo", "@foo"),
    ("bar", "@bar"),
    ("baz", "@baz{safe}"),
    ("total", "@total{$0,0.00}"
]

You can also supply a Callback to the HoverTool, to build custom interactions on hover. In this case you may want to turn the tooltips off by setting tooltips=None.

Warning

Hover tool does not currently work with the following glyphs:

  • annulus
  • arc
  • bezier
  • image
  • image_rgba
  • image_url
  • multi_line
  • oval
  • patch
  • quadratic
  • ray
  • segment
  • text
anchor

property type: Enum ( LegendLocation )

If point policy is set to “snap_to_data”, anchor defines the attachment point of a tooltip. The default is to attach to the center of a glyph.

attachment

property type: Enum ( Enumeration(horizontal, vertical) )

Whether tooltip’s arrow should appear in the horizontal or vertical dimension.

callback

property type: Instance ( Callback )

A callback to run in the browser whenever the input’s value changes. The cb_data parameter that is available to the Callback code will contain two HoverTool specific fields:

Index:object containing the indices of the hovered points in the data source
Geometry:object containing the coordinates of the hover cursor
line_policy

property type: Enum ( Enumeration(prev, next, nearest, interp, none) )

When showing tooltips for lines, whether the tooltip position should be the “previous” or “next” points on the line, the nearest point to the current mouse position, or interpolate along the line to the current mouse position.

mode

property type: Enum ( Enumeration(mouse, hline, vline) )

Whether to consider hover pointer as a point (x/y values), or a span on h or v directions.

names

property type: List ( String )

A list of names to query for. If set, only renderers that have a matching value for their name attribute will be used.

point_policy

property type: Enum ( Enumeration(snap_to_data, follow_mouse, none) )

Whether the tooltip position should snap to the “center” (or other anchor) position of the associated glyph, or always follow the current mouse cursor position.

renderers

property type: List ( Instance ( Renderer ) )

An explicit list of renderers to hit test again. If unset, defaults to all renderers on a plot.

show_arrow

property type: Bool

Whether tooltip’s arrow should be showed.

tooltips

property type: Either ( String , List ( Tuple ( String , String ) ) )

The (name, field) pairs describing what the hover tool should display when there is a hit.

Field names starting with “@” are interpreted as columns on the data source. For instance, “@temp” would look up values to display from the “temp” column of the data source.

Field names starting with “$” are special, known fields:

$index:index of selected point in the data source
$x:x-coordinate under the cursor in data space
$y:y-coordinate under the cursor in data space
$sx:x-coordinate under the cursor in screen (canvas) space
$sy:y-coordinate under the cursor in screen (canvas) space
$color:color data from data source, with the syntax: $color[options]:field_name. The available options are: ‘hex’ (to display the color as a hex value), and ‘swatch’ to also display a small color swatch.

Additional format options safe and Numbro format codes can be included in a post-fix brace block on field names.

[("total", "@total{$0,0.00}"),
 ("data", "@data{safe}")]

Including {safe} after a field name will override automatic escaping of the tooltip data source. Any HTML tags in the data tags will be rendered as HTML in the resulting HoverTool output. See Custom Tooltip for a more detailed example.

None is also a valid value for tooltips. This turns off the rendering of tooltips. This is mostly useful when supplying other actions on hover via the callback property.

Note

The tooltips attribute can also be configured with a mapping type, e.g. dict or OrderedDict. However, if a dict is used, the visual presentation order is unspecified.

behavior

property type: Enum ( Enumeration(select, inspect) )

This tool can be configured to either make selections or inspections on associated data sources. The difference is that selection changes propagate across bokeh and other components (e.g. selection glyph) will be notified. Inspecions don’t act like this, so it’s useful to configure callback when setting behavior=’inspect’.
