I have created a diurnal plot of date vs. time but it is rather messy and I'd prefer to create a heatmap. Something similar has been done here, but it doesn't work as I can't parse the time in as well. I tried this which works for the x-axis but I can't do the y.
Ideally, it would have a legend on the size showing how much data is in each 2D bin. How do I parse the x and y axis in such that numpy.histogram2D/imshow can read it or meshgrid/pcolormesh can be used?
