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

散景 是一个Python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 类创建一个新的 Figure 用于绘图。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.diamond()函数

bokeh 库的绘图模块中的diamond()函数用于配置和添加菱形字形到此图。

Syntax: diamond(x, y, size=4, angle=0.0, *, angle_units=’rad’, fill_alpha=1.0, fill_color=’gray’, line_alpha=1.0, line_cap=’butt’, line_color=’black’, line_dash=[], line_dash_offset=0, line_join=’bevel’, line_width=1, name=None, 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 markers.
• y: This parameter is the y-coordinates for the center of the markers.
• size: This parameter is the size (diameter) values for the markers in screen space units.
• angle: This parameter is the angles to rotate the markers.
• fill_color: This parameter is the fill color values for the markers.
• line_color: This parameter is the line color values for the markers with default value of black.1.
• name: This parameter is the user-supplied name for this model.
• tags: This parameter is the user-supplied values for this model.

Return: This method return the GlyphRenderer value.
