Though the question may seem strange, sometimes it really can be useful. For example, I have to build a histogram using plt.hist, but I am not going to plot it, only to send the heights of the bars to the front-end side for actual plotting, and since the back-end side is run on an Ubuntu Server instance, I cannot install matplotlib via pip. Is it possible in general? Are there any other options in my particular case?
If you just want the histogram values, then just calculate them directly using something like numpy.histogram.
