isoview - set scales for isometric plot (do not change the size of the window)
This function is obsolete, use preferably the frameflag=4 plot2d option which enable window resizing.
isoview is used to have isometric scales on the x and y axes. It does not change the size of the graphics window. The rectangle xmin, xmax, ymin, ymax will be contained in the computed frame of the graphics window. isoview set the current graphics scales and can be used in conjunction with graphics routines which request the current graphics scale (for instance strf="x0z" in plot2d).
