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

bokeh 库的绘图模块中的circle_cross()函数用于配置和添加 circle_cross 字形到这个图中。

Syntax: circle_cross(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_alpha: This parameter is the fill alpha values for the markers.
• fill_color: This parameter is the fill color values for the markers.
• line_alpha: This parameter is the line alpha values for the markers with default value of 1.0 .
• line_cap: This parameter is the line cap values for the markers with default value of butt.
• line_color: This parameter is the line color values for the markers with default value of black.
• line_dash: This parameter is the line dash values for the markers with default value of [].
• line_dash_offset: This parameter is the line dash offset values for the markers with default value of 0.
• line_join: This parameter is the line join values for the markers with default value of bevel.
• line_width: This parameter is the line width values for the markers 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.

示例 1：

# Implementation of bokeh function
    
import numpy as np 
from bokeh.plotting import figure, output_file, show
    
plot = figure(plot_width = 300, plot_height = 300)
plot.circle_cross(x = [1, 2, 3], y = [3, 7, 5],
          size = 20, color ="green", alpha = 0.6)
    
show(plot)

输出：

示例 2：

# Implementation of bokeh function
   
import numpy as np 
from bokeh.plotting import figure, output_file, show
   
x = [1, 7, 3, 4, 5]
y = [6, 2, 8, 7, 3]
  
output_file("geeksforgeeks.html")
  
p = figure(plot_width = 300, plot_height = 300)
  
# add both a line and circles on the same plot
p.line(x, y, line_width = 2)
p.circle_cross(x, y, fill_color ="red",
               line_color ="green",
               alpha = 0.6, size = 12)
  
show(p)

输出：
