I have been working on this for longer than I want to admit to, but I'm finding no answers, and have no idea how this can be done.

This is MMA version 12.1

I'm trying to change the data size and color of the points in a simple 2D plot.

This is what I have:

I'm just trying to be able to make the points larger/smaller, AND change the color, so they are more prominent, but so far, it's like pulling teeth. Anyone have some suggestions please?

Thank You

Testdata = {{5, 5}, {2, 2}};
ListPlot[
 List /@ Testdata,
 PlotStyle -> {Directive[Red, PointSize[0.02]],
               Directive[Blue, PointSize[0.04]]}
]

plot

  • List /@ to make ListPlot consider the two points as two different plots; your case would be ambiguous otherwise: is {5, 5} to be understood as two ordinate values with implicit abscissae, or a single point?
  • you can't have multiple PlotStyles; instead, have one PlotStyle, with a list of Directives, one for each plot.
