Quality Histogram - Cannot start Decorator

I have a stl and an obj File of an object. And I want to use the "Compute curvature principal directions". That works also fine. But I need a scale of the colores. And I found a post to use the "Show Face Quality Histogram". But then I get the following error: CANNOT START DECORATOR: the layer does not contain face quality

Or is there another way to show a scale of the different colors?

What I am doing wrong? How can I fix the problem? Sorry I am new in meshlab.

Thanks for helping.

Best Nick

The filter Compute curvature principal directions store Gaussian or Mean Curvature inside the per-vertex quality, so you have to use the "Show Vertex Quality Histogram" and not per-face.
