So basically for my axis function I have a function in the form of (t/4e6)*100.
Is there any way I can replace the 4e6 by something like sum(dataset_a)?
Unfortunately they code which evaluates the axis function doesn't do the
dataset substitution, unlike other places which evaluate expressions. I
assume making a new t_new, which is t/t.max() is no use?
I can't think of a workaround for this, as the evaluation code is pretty
strict on what's accepted. Perhaps it's possible to do something
horrible, like add add a python module to the custom dialog to import
veusz, and extract the data out of window.document.data. It would be
nice to remove this limitation.
The next question would be: can I actually also put a text box that essentially
puts this value on the plot somewhere (so basically adding a parameter
calculated based on the data to a text box)?
Again, this isn't possible. It would be a nice feature to allow
expansion of Python expressions within text labels, though.
The only work around would be a Tools Plugin that you would have to
manually run to modify the document to set both of these.
