Hello all,

How can I change the font size of texts in a vtkCubeAxesActor? Modifying TextProperty doesn’t work for me

vtkSmartPointer axesActor = vtkSmartPointer::New();  
axesActor-\>SetXTitle(“X”);  
axesActor-\>GetTitleTextProperty(0)-\>SetFontSize(30);  
axesActor-\>GetLabelTextProperty(0)-\>SetFontSize(30);

my vtk version is 9.1.0

Any help is appreciated!
