I do a lot of work remotely and am currently creating a cgPlot and then writing to a png file, saving a series of pngs to create a movie. But when I do this it can take 20 seconds or so to save 1 png, while if I do this on campus then it only takes 0.5 seconds to save the plot as a png. Is there another and/or more efficient of being able to plot and save the plot as a png when connected remotely through a SSH connection?

Are you displaying the image before you save it? If you are, you should consider using the Z-buffer device to generate generate and save the image without displaying it. An example how to use the Z device is shown below: pro dj_z_test Set_PLOT, 'Z' Device, SET_RESOLUTION=[500,500], DECOMPOSED=1, SET_PIXEL_DEPTH=24 plot, findgen(10) t = tvrd(/TRUE) WRITE_JPEG, "test_new.png", t, /TRUE set_plot, 'win' end
