It would be nice if there was an option to let TGaxis behave in "NDC" coordinates, as if it were a TLegend. In order to follow the zooming of the primary axes.
According to couet, the inherited function TGaxis::SetNDC() exists but does not yet behave correctly.

Additional context
An alternative / workaround is to have a TTimer modifying the axes every 0.5 seconds to reflect zoom updates. Or to connect the Modified() signal with a modify-slot.
Just for the record, I currently use this fully functional workaround with the signal-slot mechanism:
