Plot two datasets together

[alessandropeca]

Is it possible to plot together (with different colors) two different data sets? I think it could be very useful to show the differences in two datasets.

You can do that using the fig argument:

fig = corner.corner(dataset1, ..., color="C0", weights=np.ones(len(dataset1))/len(dataset1))
corner.corner(dataset2, ..., color="C1", fig=fig, weights=np.ones(len(dataset2))/len(dataset2))

If you have different numbers of points you'll need to use the weights argument to re-weight the points to get the same normalization as above, but you can leave that off if they are the same size.

Thank you!

Hi guys, This is an old one, but since it is not closed, I decided to ask my question here, instead of opening a new issue. So, I found this feature to be very useful, and I have succeeded in using it. Now, however, I'm interesting in getting a corner plot with, say, two datasets but with different number of (constrained) parameters, e.g., [a,b,c] for one dataset and [b,c] for the other. So my question is, is there a way to make such a combination? Here is an example of what I have in mind, in case I'm not clear enough with my description above.
