I am trying to use
PlotMarkers -> Automatic or its equivalent for
Show[ListPlot[..., PlotMarkers -> Automatic], ListPlot[...] ,...] to make each list plot display a different plot marker shape/type, but it gives the same shape for every list plot. Is there some way to do this, or do I have to give each list plot
PlotMarkers -> "shape" manually?
Any help would be appreciated.
