For plotting larger areas (say, Europe or the whole globe), it can be best to switch to cell shading for a faster plot. For small areas (e.g. the size of a small country), grid shading will give the most accurate results, but this can be slower for larger areas.

Keep an eye on memory usage

...

The memory used during an on-screen interactive plot is released when the window is closed. But if you plot to a file (e.g. PNG, PDF, PS) the memory will not be released and you may have to kill the uPlotBatch process in order to release it.
