There are two options here: either you can redfine `stackhist` to take a dummy second argument and pass an empty string to it, or you can just reset the y axis label after plotting:". You want to put multiple graphs on one page.

Explanation --- look at your plot to see what the legend is referring then name it accordingly. The facet_grid() function is the one which enables us to draw several graphs side by side. Let's generate some data that could be the result of a hypothetical experiment to evaluate the benefits of a performance optimization in a virtual machine. The facet-grid.
