QPlot: qgimage

qgimage Place an image with data and paper coordinates

Help text:

qgimage(xywh_data, xywh_paper, img) places the image on a location in the graph specified by both data coordinates and image coordinates.
For example: qgimage([5 5 0 0],[0 0 36 72],img) creates an image of 0.5x1" at data location (5,5). qgimage([5 nan 0 5],[0 36 72 0],img) creates an
image 1" wide, 5 data units high, at x=5, 1" below the top of the graph.
Etc.
