Can you post a screen shot/example of what this looks like? Maybe also a test (our plotting "tests" are just making sure you can call the functions)? |

In this example sigma is continuous and gamma discrete
Densityplot is already included in our tests (see #2741) |

ups! I just notice a problem (with the xticks) |

Better to set density=None to True.

That will only change the scale of y. But that scale is not plotted, the yticks are set to an empty list.

This is how it looks like with the fix
