Python Bokeh - Plotting Diamond Dots on a Graph

Last Updated : 03 Jul, 2020

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 dots on a graph. Plotting diamond with dots on a graph can be done using the diamond_dot() method of the plotting module.

plotting.figure.diamond_dot()

Syntax : diamond_dot(parameters) Parameters :

x : x-coordinates of the center of the diamond dot markers

y : y-coordinates of the center of the diamond dot markers

size : diameter of the diamond dot markers, default is 4

angle : angle of rotation of the diamond dot markers, default is 0

angle_units : unit of the angle, default is rad

fill_alpha : fill alpha value of the diamond dot markers

fill_color : fill color value of the diamond dot 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

default is solid

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.

Python3

# importing the modules from bokeh.plotting import figure, output_file, show     # file to save the model output_file("gfg.html")     # instantiating the figure object graph = figure(title = "Bokeh Diamond Dot Graph")   # the points to be plotted x = [-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5] y = [i ** 2 for i in x]  # plotting the graph graph.diamond_dot(x, y, size = 25, fill_color = None)   # displaying the model show(graph)

Output :

Example 2 :In this example we will be plotting the diamond dots where the sizes are in proportion to their values and various other parameters.

Python3

# importing the modules from bokeh.plotting import figure, output_file, show     # file to save the model output_file("gfg.html")     # instantiating the figure object graph = figure(title = "Bokeh Diamond Dot Graph")   # name of the x-axis graph.xaxis.axis_label = "x-axis"    # name of the y-axis graph.yaxis.axis_label = "y-axis"   # the points to be plotted x = [-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5] y = [i ** 2 for i in x]   # size of the diamonds size = [i * 2 for i in y]   # angle of the diamonds angle = 10  # fill color value fill_color = "yellow"  # color of the line line_color = "red"  # name of the legend legend_label = "Sample Dashes"    # plotting the graph graph.diamond_dot(x, y,                   size = size,                   angle = angle,                   fill_color = fill_color,                   line_color = line_color,                   legend_label = legend_label)     # displaying the model show(graph)
