Hi Mark, I'm not sure I understand what you're running into. Are you trying to overlay on a previous plot in the viewport, or are plots in other viewports disappearing? The mp_demo script makes a whole batch of map projection plots in viewports; take a look at that script and see if it helps you. (find it with the Unix command Fgo mp_demo.jnl) Ansley Mark.Collier@csiro.au wrote:
