In this chapter, we will discuss Bokeh – Circle Glyphs. The figure object has many methods using which vectorized glyphs of different shapes such as circles, rectangles, polygon, etc. can be drawn.

Methods are available for drawing Bokeh circle glyphs −

circle()

The circle() method adds a circle glyph to the figure and needs x and y coordinates of its center. Additionally, it can be configured with the help of parameters such as fill_color, line-color, line_width, etc.

circle_cross()

The circle_cross() method adds circle glyph with a ‘+’ cross through the center.

circle_x()

The circle_x() method adds circle with an ‘X’ cross through the center.

Example

The following example shows the use of various added to the figure −

from bokeh.plotting import figure, output_file, show
plot = figure(plot_width = 300, plot_height = 300)
plot.circle(x = [1, 2, 3], y = [3,7,5], size = 20, fill_color = 'red')
plot.circle_cross(x = [2,4,6], y = [5,8,9], size = 20, fill_color = 'blue',fill_alpha = 0.2, line_width = 2)
plot.circle_x(x = [5,7,2], y = [2,4,9], size = 20, fill_color = 'green',fill_alpha = 0.6, line_width = 2)
show(plot)
