In this chapter, we will discuss Bokeh Rectangle Oval and Polygon. It is possible to render rectangles, ellipse,s, and polygons in a Bokeh figure. The rect() method of the Figure class adds a rectangle glyph based on x and y coordinates of the center, width, and height. The square() method on the other hand has a size parameter to decide dimensions.

The ellipse() and oval() methods add an ellipse and oval glyph. They use a similar signature to that of rect() having x, y,w, and h parameters. Additionally, the angle parameter determines rotation from horizontal.

Example Of Bokeh Rectangle Oval and Polygon

The following code shows the use of different shape glyph methods −

from bokeh.plotting import figure, output_file, show
fig = figure(plot_width = 300, plot_height = 300)
fig.rect(x = 10,y = 10,width = 100, height = 50, width_units = 'screen', height_units = 'screen')
fig.square(x = 2,y = 3,size = 80, color = 'red')
fig.ellipse(x = 7,y = 6, width = 30, height = 10, fill_color = None, line_width = 2)
fig.oval(x = 6,y = 6,width = 2, height = 1, angle = -0.4)
show(fig)
