Controller for navigation dimension > 2 is broken

[thomasaarholt]

The navigator for signals with navigation dimension > 2 doesn't work properly. There is a small window but I can't drag the sliders.

Test code:

hs.signals.Signal1D(np.random.rand(5,5,5,5)).plot()

Does this work for you in normal hspy? This has always failed for me.

[thomasaarholt]

Yes, it works fine.

For reference, this is the size of the "navigation sliders" window in the UI. This is where the problem is.

In both HS and UI I can manually step through the 0th and 1st axis (technically, these should be called 1st and 2nd, no?) in the chequers-looking window above, but I cannot step through the 2nd axis in the UI as it is "under". In HS I need to use the slider to access this dimension.

Workaround is to input a number in the text-dialog, but I agree this should be fixed. Hspy way now worked for me, so I think I might have to check if/how this was fixed in traitsui code :)
