bokeh.models.plots¶

Models for representing top-level plot objects.

class Plot(**kwargs)[source]¶

Bases: bokeh.models.layouts.LayoutDOM

Model representing a plot, containing glyphs, guides, annotations.

above¶

property type: List ( Instance ( Renderer ) )

A list of renderers to occupy the area above of the plot.

aspect_scale¶

property type: Float

A value to be given for increased aspect ratio control. This value is added multiplicatively to the calculated value required for match_aspect. aspect_scale is defined as the ratio of width over height of the figure.

For example, a plot with aspect_scale value of 2 will result in a square in data units to be drawn on the screen as a rectangle with a pixel width twice as long as its pixel height.

Note

This setting only takes effect if match_aspect is set to True.

background_fill_alpha¶

property type: NumberSpec

The fill alpha for the plot background style.

background_fill_color¶

property type: ColorSpec

The fill color for the plot background style.

below¶

property type: List ( Instance ( Renderer ) )

A list of renderers to occupy the area below of the plot.

border_fill_alpha¶

property type: NumberSpec

The fill alpha for the plot border style.

border_fill_color¶

property type: ColorSpec

The fill color for the plot border style.

center¶

property type: List ( Instance ( Renderer ) )

A list of renderers to occupy the center area (frame) of the plot.

extra_x_ranges¶

property type: Dict ( String , Instance ( Range ) )

Additional named ranges to make available for mapping x-coordinates.

This is useful for adding additional axes.

extra_y_ranges¶

property type: Dict ( String , Instance ( Range ) )

Additional named ranges to make available for mapping y-coordinates.

This is useful for adding additional axes.

frame_height¶

property type: Int

The height of a plot frame or the inner height of a plot, excluding any axes, titles, border padding, etc.

frame_width¶

property type: Int

The width of a plot frame or the inner width of a plot, excluding any axes, titles, border padding, etc.

hidpi¶

property type: Bool

Whether to use HiDPI mode when available.

inner_height¶

property type: Int

This is the exact height of the plotting canvas, i.e. the height of the actual plot, without toolbars etc. Note this is computed in a web browser, so this property will work only in backends capable of bidirectional communication (server, notebook).

Note

This is an experimental feature and the API may change in near future.

inner_width¶

property type: Int

This is the exact width of the plotting canvas, i.e. the width of the actual plot, without toolbars etc. Note this is computed in a web browser, so this property will work only in backends capable of bidirectional communication (server, notebook).

Note

This is an experimental feature and the API may change in near future.

left¶

property type: List ( Instance ( Renderer ) )

A list of renderers to occupy the area to the left of the plot.

lod_factor¶

property type: Int

Decimation factor to use when applying level-of-detail decimation.

lod_interval¶

property type: Int

Interval (in ms) during which an interactive tool event will enable level-of-detail downsampling.

lod_threshold¶

property type: Int

A number of data points, above which level-of-detail downsampling may be performed by glyph renderers. Set to None to disable any level-of-detail downsampling.

lod_timeout¶

property type: Int

Timeout (in ms) for checking whether interactive tool events are still occurring. Once level-of-detail mode is enabled, a check is made every lod_timeout ms. If no interactive tool events have happened, level-of-detail mode is disabled.

match_aspect¶

property type: Bool

Specify the aspect ratio behavior of the plot. Aspect ratio is defined as the ratio of width over height. This property controls whether Bokeh should attempt the match the (width/height) of data space to the (width/height) in pixels of screen space.

Default is False which indicates that the data aspect ratio and the screen aspect ratio vary independently. True indicates that the plot aspect ratio of the axes will match the aspect ratio of the pixel extent the axes. The end result is that a 1x1 area in data space is a square in pixels, and conversely that a 1x1 pixel is a square in data units.

Note

This setting only takes effect when there are two dataranges. This setting only sets the initial plot draw and subsequent resets. It is possible for tools (single axis zoom, unconstrained box zoom) to change the aspect ratio.

Warning

This setting is incompatible with linking dataranges across multiple plots. Doing so may result in undefined behaviour.

min_border¶

property type: Int

A convenience property to set all all the min_border_X properties to the same value. If an individual border property is explicitly set, it will override min_border.

min_border_bottom¶

property type: Int

Note

This is a minimum. The padding region may expand as needed to accommodate titles or axes, etc.

min_border_left¶

property type: Int

Minimum size in pixels of the padding region to the left of the central plot region.

Note

This is a minimum. The padding region may expand as needed to accommodate titles or axes, etc.

min_border_right¶

property type: Int

Minimum size in pixels of the padding region to the right of the central plot region.

Note

This is a minimum. The padding region may expand as needed to accommodate titles or axes, etc.

min_border_top¶

property type: Int

Minimum size in pixels of the padding region above the top of the central plot region.

Note

This is a minimum. The padding region may expand as needed to accommodate titles or axes, etc.

outer_height¶

property type: Int

This is the exact height of the layout, i.e. the height of the actual plot, with toolbars etc. Note this is computed in a web browser, so this property will work only in backends capable of bidirectional communication (server, notebook).

Note

This is an experimental feature and the API may change in near future.

outer_width¶

property type: Int

This is the exact width of the layout, i.e. the height of the actual plot, with toolbars etc. Note this is computed in a web browser, so this property will work only in backends capable of bidirectional communication (server, notebook).

Note

This is an experimental feature and the API may change in near future.

This property can be manipulated by hand, but the add_glyph and add_layout methods are recommended to help make sure all necessary setup is performed.

reset_policy¶

property type: Enum ( ResetPolicy )

How a plot should respond to being reset. By deafult, the standard actions are to clear any tool state history, return plot ranges to their original values, undo all selections, and emit a Reset event. If customization is desired, this property may be set to "event_only", which will suppress all of the actions except the Reset event.

Return whether this plot is in a given row of a GridPlot.

Parameters

row (int) – index of the row to test
gridplot (GridPlot) – the GridPlot to check

Returns

bool

select(*args, **kwargs)[source]¶

Query this object and all of its references for objects that match the given selector.

There are a few different ways to call the select method. The most general is to supply a JSON-like query dictionary as the single argument or as keyword arguments:

Parameters: selector (JSON-like) – some sample text
Keyword Arguments: kwargs – query dict key/values as keyword arguments

Additionally, for compatibility with Model.select, a selector dict may be passed as selector keyword argument, in which case the value of kwargs['selector'] is used for the query.

For convenience, queries on just names can be made by supplying the name string as the single parameter:

Parameters: name (str) – the name to query on

Also queries on just type can be made simply by supplying the Model subclass as the single parameter:

Parameters: type (Model) – the type to query on
Returns: seq[Model]

Examples

# These three are equivalent
p.select(selector={"type": HoverTool})
p.select({"type": HoverTool})
p.select(HoverTool)

# These two are also equivalent
p.select({"name": "mycircle"})
p.select("mycircle")

# Keyword arguments can be supplied in place of selector dict
p.select({"name": "foo", "type": HoverTool})
p.select(name="foo", type=HoverTool)
