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.

class Action(**kwargs)[source]¶

Bases: bokeh.models.tools.Tool

class HoverTool(**kwargs)[source]¶

Bases: bokeh.models.tools.Inspection

toolbar 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
oval
patch

quadratic
ray
text

anchor¶

property type: Enum ( Anchor )

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

formatters¶

property type: Dict ( String , Enum ( TooltipFieldFormatter ) )

Specify the formatting scheme for data source columns, e.g.

tool.formatters = dict(date="datetime")

will cause format specifications for the “date” column to be interpreted according to the “datetime” formatting scheme. The following schemed are available:

“numeral”:	Provides a wide variety of formats for numbers, currency, bytes, times, and percentages. The full set of formats can be found in the `NumeralTickFormatter` reference documentation.
“datetime”:	Provides formats for date and time values. The full set of formats is listed in the `DatetimeTickFormatter` reference documentation.
“printf”:	Provides formats similar to C-style “printf” type specifiers. See the `PrintfTickFormatter` reference documentation for complete details.

If no formatter is specified for a column name, the default "numeral" formatter is assumed.

line_policy¶

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

When showing tooltips for lines, designates 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.

Field names that begin with @ are associated with columns in a ColumnDataSource. For instance the field name "@price" will display values from the "price" column whenever a hover is triggered. If the hover is for the 17th glyph, then the hover tooltip will correspondingly display the 17th price value.

Note that if a column name contains spaces, the it must be supplied by surrounding it in curly braces, e.g. @{adjusted close} will display values from a column named "adjusted close".

By default, values for fields (e.g. @foo) are displayed in a basic numeric format. However it is possible to control the formatting of values more precisely. Fields can be modified by appending a format specified to the end in curly braces. Some examples are below.

"@foo{0,0.000}"    # formats 10000.1234 as: 10,000.123

"@foo{(.00)}"      # formats -10000.1234 as: (10000.123)

"@foo{($ 0.00 a)}" # formats 1230974 as: $ 1.23 m

Specifying a format {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.

logo¶

property type: Enum ( Enumeration(normal, grey) )

What version of the Bokeh logo to display on the toolbar. If set to None, no logo will be displayed.

merge_tools¶

property type: Bool

Merge all the tools together so there is one tool to control all the plots.

toolbar_location¶

property type: Enum ( Location )

Should the toolbar be presented as if it was stuck to the above, right, left, below edge of a plot. Default is right.

tools¶

property type: List ( Instance ( Tool ) )

A list of tools to add to the plot.

class WheelPanTool(**kwargs)[source]¶

Bases: bokeh.models.tools.Scroll

toolbar icon:

The wheel pan tool allows the user to pan the plot along the configured dimension using the scroll wheel.

dimension¶

property type: Enum ( Dimension )

Which dimension the wheel pan tool is constrained to act in. By default the wheel pan tool will pan the plot along the x-axis.
