Hello,

I am using Paraview (5.8) to do an animation with different 3D objects. I am wondering if it is possible to create a scale bar (just a line) in Paraview (in micrometers) and to visualize it throughout the video. I did not manage to do it with the color editor. I do not know if it is possible with the ruler?

Thanks in advance,  
Yousr
