How do I plot graphics to the image display, xgterm, or any other graphics device?
If the stdgraph environment variable is set to a graphics device for which the CL uses its own built-in kernel (such as xgterm or xterm), PyRAF uses its own built-in graphics window. Since the PyRAF graphics window requires X-windows, you can’t run graphics tasks when remotely logged in without X-windows (e.g. through a terminal emulator.) For most purposes the PyRAF graphics window is preferred. Note that you can run PyRAF in an xgterm terminal window, but the graphics will appear in the standard PyRAF plot window.
