I am plotting 3D meshes of brains with their respective activation maps (see screenshot below). Each vertex has a color value which represents the intensity of activation in that area. I want to plot a single red marker on the vertex with the maximum intensity activation. Using the x,y,z coordinates of the vertex with the maximum intensity, I have tried to plot a single marker with 3d scatter but it gives me the error:
Invalid value of type ‘numpy.float64’ received for the ‘x’ property of scatter3d
Received value: -23.87
Is there a way to plot only one marker given its x,y,z coordinates? Am I missing something? I can plot the vertex with the maximum activation by changing its color on the mesh but I would prefer to get a 3d marker instead.
Your help will be highly appreciated!
