In the context of Markov Chain Monte Carlo, I want to plot the 2D posterior distribution for a parameter estimation problem using corner.corner. The figure that I have now looks like this:

example posterior pdf

In the contour plot, the contours are defined by probability quantiles, such that what is outside the contours has low probability.

I would like to know if it is possible to remove the samples in the background (i.e. the grey dots) outside of the probability contours.

To remove the datapoints outside from contour, you have to plot_datapoints=False in corner.corner command.

I hope it will simply solve your issue.

  • This worked. I saw this kwarg in the corner.hist2d() function in the API documentation, but not for corner.corner. They must have forgotten to write it. – Bremsstrahlung Apr 03 '20 at 16:12
