Styling Using both Relative and Absolute Units


I’d like to better understand how sizing and offsets work for histograms. Right now, I’m defining custom styles for plotting, and I’m curious how the offset units for various elements within a pad work.

For example, in HTML, there are both relative and absolute units, e.g. rem/px. I’m wondering in essence whether I’m able to set and manipulate histogram elements like axis labels according to both of these unit styles fluidly. I wasn’t able to find any documentation on the matter, so any assistance would be greatly appreciated.

Dear @rhillman

Probably @couet can help you better understand the structure of the histogram axes.


Welcome to the ROOT forum.

Can you provide a small demonstrator macro showing what kind of “offset” you are talking about ?
