Python Bokeh – Plotting Diamond Crosses on a Graph

Bokeh is a Python interactive data visualization. It renders its plots using HTML and JavaScript. It targets modern web browsers for presentation providing elegant, concise construction of novel graphics with high-performance interactivity. Bokeh can be used to plot diamond with crosses on a graph. Plotting diamond with crosses on a graph can be done using the diamond_cross() method of the plotting module.

plotting.figure.diamond_cross()

Syntax : diamond_cross(parameters) Parameters : 

• x : x-coordinates of the center of the diamond cross markers
• y : y-coordinates of the center of the diamond cross markers
• size : diameter of the diamond cross markers, default is 4
• angle : angle of rotation of the diamond cross markers, default is 0
• angle_units : unit of the angle, default is rad
• fill_alpha : fill alpha value of the diamond cross markers
• fill_color : fill color value of the diamond cross markers
• line_alpha : percentage value of line alpha, default is 1
• line_cap : value of line cap for the line, default is butt
• line_color : color of the line, default is black
• line_dash : value of line dash such as :
  • solid
  • dashed
  • dotted
  • dotdash
  • dashdot
• line_dash_offset : value of line dash offset, default is 0
• line_join : value of line join, default in bevel
• line_width : value of the width of the line, default is 1
• name : user-supplied name for the model
• tags : user-supplied values for the model

Other Parameters : 

• alpha : sets all alpha keyword arguments at once
• color : sets all color keyword arguments at once
• legend_field : name of a column in the data source that should be used
• legend_group : name of a column in the data source that should be used
• legend_label : labels the legend entry
• muted : determines whether the glyph should be rendered as muted or not, default is False
• name : optional user-supplied name to attach to the renderer
• source : user-supplied data source
• view : view for filtering the data source
• visible : determines whether the glyph should be rendered or not, default is True
• x_range_name : name of an extra range to use for mapping x-coordinates
• y_range_name : name of an extra range to use for mapping y-coordinates
• level : specifies the render level order for this glyph

Returns : an object of class GlyphRenderer

Example 1 :In this example we will be using the default values for plotting the graph. We have provided the size and fill_color attributes to make the glyph visible. 

Output : Example 2 :In this example we will be plotting the diamond crosses with dotted lines alongside other parameters and the size of the diamond crosses are in proportion to their values. 

Output :
