There is one method I know of that you might consider to get player-controlled zooming, should you want that; use a map window. You can even add one to the Charts Window. For an example of the later, you’ll find one in the last two versions of the Flying Colors module.
I don’t use a zoom tool there but I just checked and you can add one (E.g. below). You’ll still want to prepare the image appropriately but this might help too.
In this example, the Turn Track & Sequence of Play is a map, everything else is simple chart components.
