Generate a heatmap using a scatter data set
If you don’t want hexagons, you can use numpy’s histogram2d function: import numpy as np import numpy.random import matplotlib.pyplot as plt # Generate some test data x = np.random.randn(8873) y = np.random.randn(8873) heatmap, xedges, yedges = np.histogram2d(x, y, bins=50) extent = [xedges[0], xedges[-1], yedges[0], yedges[-1]] plt.clf() plt.imshow(heatmap.T, extent=extent, origin=’lower’) plt.show() This makes a 50×50 heatmap. … Read more
