I figured out a way by using the vtkAxesActor class directly.
An example script:
from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()
renderView1 = GetActiveViewOrCreate('RenderView')
sphere1 = Sphere()
sphere1.Radius = 1.0
sphere1Display = Show(sphere1, renderView1)
sphere1Display.SetRepresentationType('Outline')
import vtk
renderer = renderView1.GetRenderer()
axes = vtk.vtkAxesActor()
#axes.SetAxisLabels(0) # 0/1 to turn off/on axis labels
transform = vtk.vtkTransform()
transform.Translate(-1.0, -1.0, -1.0)
transform.Scale(0.75, 0.75, 0.75)
axes.SetUserTransform(transform)
tprop = vtk.vtkTextProperty()
#tprop.SetFontSize(6) # seems to be overriden by vtkCaptionActor2D
tprop.SetBold(1)
tprop.SetItalic(0)
tprop.SetColor(1.0, 1.0, 1.0)
tprop.SetOpacity(1.0)
tprop.SetFontFamilyToTimes()
for label in [
axes.GetXAxisCaptionActor2D(),
axes.GetYAxisCaptionActor2D(),
axes.GetZAxisCaptionActor2D(),
]:
# set Positoin2
label.SetWidth(label.GetWidth() * 0.5)
label.SetHeight(label.GetHeight() * 0.5)
label.SetCaptionTextProperty(tprop)
renderer.AddActor(axes)
Interact()
