The problem is that nobody warrants that all the scans will have the same X
axis nor the same number of points.

Have you tried the "Specfile Multiscan" option?

That would be very easy to implement as a ScanWindow plugin (See the
PyMcaPlugins directory for examples). The only difficulty is how to deal
with different number of points (one possibility would be interpolation) or
incompatible ranges (not overlapping X axes).

It is because of all those reasons that I offer that in a format that
allows me to overcome those difficulties. I may add HDF5 export in the near
future.
