Setting of MarkerStyle does NOT work!

I was able to reproduce the problem on one computer while it works well on another.

Can you try if it works well if you

  • open a terminal window where Slicer.exe is located
  • type set SLICER_OPENGL_PROFILE=core
  • type Slicer.exe to start the application

Copy-paste this to the Python console:

import SampleData
import numpy as np
volumeNode = SampleData.SampleDataLogic().downloadMRHead()
histogram = np.histogram(arrayFromVolume(volumeNode), bins=50)

chartNode = slicer.util.plot(histogram, xColumnIndex = 1)
chartNode.SetYAxisRangeAuto(False)
chartNode.SetYAxisRange(0, 4e5)

chartNode.GetNthPlotSeriesNode(0).SetMarkerStyle(slicer.vtkMRMLPlotSeriesNode.MarkerStyleCircle)
chartNode.GetNthPlotSeriesNode(0).SetMarkerSize(15)

You may also try updating your graphics card drivers. What graphics card and driver version do you use?
