How to do it...
The following code block plots a collection of polygons that cycle through a given number of sizes and a given list of colors:
- Define the data for plotting a collection of polygons:
nsizes = 50 #number of different sizes to be used to plot the items in the collectionnpts = 100 # number of items in the collectionr = np.arange(nsizes)theta = np.linspace(0, 2*np.pi, nsizes)xx = r * np.sin(theta)
- Offset co-ordinates where the items of the collection would be plotted:
rs = np.random.RandomState([125])xo = rs.randn(npts)yo = rs.randn(npts)xyo = list(zip(xo, yo))
- Define the figure size and attach it to the canvas, and also define an axis on this figure:
figure_manager = backend_agg.new_figure_manager(1, figsize=(8,6))fig = ...
