You need to update matplotlib to a newer version

You are right, it might be good to allow switching this behavior if needed. I think I should add an option to change this from the current default behavior.

You probably need to change the Euler angle representation used for this plot. This is not related to accuracy of the trajectory. https://github.com/MichaelGrupp/evo/issues/295#issuecomment-649584091 https://github.com/MichaelGrupp/evo/issues/181#issuecomment-507675295

I don't understand - the trajectory file contains a quaternion, not RPY. So if you want to convert it to an Euler representation, you need to choose the order yourself.

I recommend to check first if matplotlib supports this font. If it's possible with matplotlib somehow, then it's also possible with evo.

The solution is only unique if there are >=3 non-colinear points in 3D space. For full details, I would recommend to check the original paper of the algorithm.
