Did you mean:

window, win, 100, 100

Or, will this get you started?

plots, [0,100,100,0], [0,0,100,100], /device

The device keyword forces the operation to occur in pixel space.
Since your coordinate axes don't seem to matter to you, this is
probably the best option. Note you can get the display size in pixels
from the !D system variable, in case you need to scale accordingly.
