Python中的 bokeh.plotting.figure.annular_wedge()函数

Bokeh是Python中的数据可视化库，提供高性能的交互式图表和绘图，输出可以在笔记本、html 和服务器等各种媒体中获得。 Figure 类创建一个用于绘图的新 Figure。它是 Plot 的子类，使用默认轴、网格、工具等简化绘图创建。

bokeh.plotting.figure.annular_wedge()函数

bokeh 库绘图模块中的ring_wedge()函数用于将 AnnularWedge 字形添加到图形中。

Syntax: annular_wedge(x, y, inner_radius, outer_radius, start_angle, end_angle, direction=’anticlock’, *, end_angle_units=’rad’, fill_alpha=1.0, fill_color=’gray’, inner_radius_units=’data’, line_alpha=1.0, line_cap=’butt’, line_color=’black’, line_dash=[], line_dash_offset=0, line_join=’bevel’, line_width=1, name=None, outer_radius_units=’data’, start_angle_units=’rad’, tags=[], **kwargs)

Parameters: This method accept the following parameters that are described below:

x: This parameter is the x-coordinates for the center of the annular wedges.
y: This parameter is the y-coordinates for the center of the annular wedges.
inner_radius: This parameter is the inner radii of the annular wedges.
outer_radius: This parameter is the outer radii of the annular wedges.
start_angle: This parameter is the angles to start the annular wedges.
end_angle: This parameter is the angles to end the annular wedges.
direction: This parameter is the direction to stroke between the start and end angles.
fill_alpha: This parameter is the fill alpha values for the annular wedges.
fill_color: This parameter is the fill color values for the annular wedges.
line_alpha: This parameter is the line alpha values for the annular wedges with default value of 1.0 .
line_cap: This parameter is the line cap values for the annular wedges with default value of butt.
line_color: This parameter is the line color values for the annular wedges with default value of black.
line_dash: This parameter is the line dash values for the annular wedges with default value of [].
line_dash_offset: This parameter is the line dash offset values for the annular wedges with default value of 0.
line_join: This parameter is the line join values for the annular wedges with default value of bevel.
line_width: This parameter is the line width values for the annular wedges with default value of 1.
mode: This parameter can be one of three values : [“before”, “after”, “center”].
name: This parameter is the user-supplied name for this model.
tags: This parameter is the user-supplied values for this model.

Other Parameters: These parameters are **kwargs that are described below:

alpha: This parameter is used to set all alpha keyword arguments at once.
color: This parameter is used to to set all color keyword arguments at once.
legend_field: This parameter is the name of a column in the data source that should be used or the grouping.
legend_group: This parameter is the name of a column in the data source that should be used or the grouping.
legend_label: This parameter is the legend entry is labeled with exactly the text supplied here.
muted: This parameter contains the bool value.
name: This parameter is the optional user-supplied name to attach to the renderer.
source: This parameter is the user-supplied data source.
view: This parameter is the view for filtering the data source.
visible: This parameter contains the bool value.
x_range_name: This parameter is the name of an extra range to use for mapping x-coordinates.
y_range_name: This parameter is the name of an extra range to use for mapping y-coordinates.
level: This parameter specify the render level order for this glyph.

Return: This method return the GlyphRenderer value.
