I'm not either. Never heard of them. Can you supply more information or context?

There are several questions here:

Are you trying to lay out three axes (one for the image, and then two long skinny ones for histograms?) If so, subplot and axes will help.

Do you have the data and just not know how to do a horizontal bar plot? If so, barh will help.

Do you not know how to gather the data for the histograms? hist will help, as will some indexing into the matrix.

Help us to help you by editing your question (NOT answering it) to reflect this information.
