Just for clarification: It seems that this only a problem if you want to export 3D data in csv format. For all the 2d data plots it works fine.

Therefore all xy, xz, ... scans will suffer from that error. However, you can still use all the other save functions. The problem is most probably an error in the csv exporter of the pyqtgraph package.

According to the PyQtGraph? documentation, this feature is not completely supported for 3D data:

It looks like that simply the implementation is missing.
