How can I obtain crosses as plot markers in a ListPlot?

I know how to obtain circles, disks, squares, using Graphics, like PlotMarkers -> {Graphics[{Red, Thick, Disk[]}, ImageSize -> 10]}. But I can't think of any way to obtain a cross this way, other than actually drawing the cross, which seems overkill. Is there a simpler way? I just need some advice on the best way to do this without too much work.

  • $\begingroup$ @Ruud3.1415 Nice! That works. To get some more fine control, you can do something like PlotMarkers -> Graphics[{Black, FontSize -> 20, Text["+"]}] $\endgroup$

Using PlotMarkers -> "+" is not a good solution, because the text is aligned with its foot at the point, not the centre of the cross.

If you want the centre of the cross to have a precise position in the plot, you can use:

cross = Graphics[{Line[{{-1,0},{1,0}}], Line[{{0,-1},{0,1}}]}] 
ListPlot[data, PlotMarkers -> {cross,0.05}]

This would be a simple solution:

ListPlot[{1, 2, 3, 4}, PlotMarkers -> Style["+", {Black, FontSize -> 20}]]

    $\begingroup$ Alternatively: ListPlot[{1, 2, 3, 4}, PlotMarkers -> Style["✚", Medium]]. $\endgroup$ Sep 6, 2017 at 13:09
  • $\begingroup$ @J.M. that would be a more aesthetic solution, I edited mine $\endgroup$
