Stacked line plots do not correctly view-to-interval #866

Closed gosselind1 closed 2 years ago

gosselind1 commented 2 years ago

Steps to reproduce:

  1. Generate two lineplots
  2. Drag one over the other to create a stack
  3. Add an interval graphic
  4. Press enter to zoom in

Expected Behavior: Zooms into a window looking similar to this: image

Actual Behavior: Zooms into a window which only accounts for the first layer (the light blue one in this case) image

Additional comment (from chat):

I think that in the case of view-to-intervals, that it would make sense to translate the interval to graph coordinates (pixels) and then back to each layer's fractional coordinates and then determine the appropriate y-values (in pixels) for that layer - then use the min/max across all layers to figure out y-scaling. x-axis adjustment is obvious and can be done using any layer.
