API to get current plot area width & height

Subtracting the margins should work, I think

Pixel dimensions of paper coordinates

Trying to get, e.g., two annotations to lay one next to/above/below the other on a figure using xref=‘paper’, but (0,0) and (1,1) in the paper domain correspond to the plottable area, not the entire figure. Since layout.height and layout.width set the pixel size of the figure, I need to figure out how to back out the actual pixel dimensions of the paper coordinates. I tried subtracting out the margins, but that’s still not quite right (see code and image below). Anyone know how I can get the ex…
