Make labels for mathematical plot face always the camera In a mathematical plot, the labels (the numers on the tick-marks) for the coordinate axes usually always face the camera like in this plot



I've learned that in Blender, you can achieve this by setting Track To constraints on the text.



Three questions:


Is this the best way to do it for text?
The docu for Track To is rather short. What is the correct setting to make the text face the camera and why?
Is anyone aware of a script that possibly creates such a box, the ticks, and the labels automatically? Maybe this was already done for plotting mathematical surfaces.
I think it's the best way ; unless a script exists that allows billboard rendering for text object, but I don't know any.
Displaying the Axis of the text object helps a lot!


"To" is the axis that points to the target ; for a text object, it's Z.
"Up" is the axis that point upwards ; for a text object, it's Y.
