Hi, I would like to produce a scatter plot with roughly 200 mio points. Because the points are so numerous I rather need a point density plot.
I use numpy. Right now I loop over the individual data points and make a where query on a meshgrid. ind = where((x_grid == x_points[i]) & (y_grid == y_points[i]) ) counter_grid[ind] += 1 This is really slow. I'm sure there's a better solution already out there. Kind regards! -- http://mail.python.org/mailman/listinfo/python-list
