"Plot Selected Groups" not working after import Larch session using "Read Larch Session"

[rarivera10]

After I import a previously saved Larch session using "Read Larch Session", if I try to plot multiple groups, then nothing plots and I receive an error in the terminal saying:

Traceback (most recent call last):
File "C:\Users\rariv\xraylarch\lib\site-packages\larch\wxxas\xasnorm_panel.py", line 586, in onPlotSel
trace = {'xdata': dgroup.xplot,
AttributeError: 'Group' object has no attribute 'xplot'

This did not happen before updating to 0.9.80 on Windows.

If I open new data files from CSV and I plot multiple groups, then things work normally however.

@rarivera10 Oh, sorry for the trouble. Can you send a session file that shows this?

[rarivera10]

Yes! Github doesn't let me attach a .larix file so I sent the file in an email to newville@cars.uchicago.edu.

@rarivera10

I believe this is fixed in the "development version", which you should be able to install with

   python -m pip install https://millenia.cars.aps.anl.gov/xraylarch/downloads/xraylarch-latest-py3-none-any.whl

On Windows: Open a command terminal (with “cmd” in the Start Menu’s search box). This should put you in a folder like
C:\Users\yourname
There should be a folder called xraylarch there. If not, check the properties of the Desktop icons for where xraylarch is installed. Once that is found, you can then you can type:

     xraylarch\python -pip install https://millenia.cars.aps.anl.gov/xraylarch/downloads/xraylarch-latest-py3-none-any.whl

Downloaded and I receive a new error now:

Traceback (most recent call last):
File "C:\Users\rariv\xraylarch\lib\site-packages\larch\wxxas\xasnorm_panel.py", line 586, in onPlotSel
'ydata': getattr(dgroup, yarray_name) + ix*voff,
AttributeError: 'Group' object has no attribute 'norm_mback'

When normalization is set to mback on a group and I try to plot multiple groups, then I receive this error. However, plotting multiple groups with polynomial normalization works great. Mback works fine when I plot current group, I only see the problem when plotting multiple groups and one of them uses mback for normalization.

Thankfully, I only need polynomial normalization but figured I'd report the mback error as well since I stumbled upon it.

Thank you for your help!! I have enjoyed using Larix and am excited for the improvements you continue to make to the software.

@rarivera10 Thanks for the report and sorry for that. That's clear enough that I'll look into (maybe in a couple of days).

@newville this bug with 'norm_mback' was already reported in #511

@maurov Thanks, that's helpful, and I agree these must be related... hope to fix soon!

[newville]

@rarivera10 @maurov I think this is fixed in the master branch. I fixed the code to check for the arrays from mback, and run that if needed (and be more aggressive about running mback n general), and I wasn't able to make it happen. But, I'm not certain I was trying every possible approach. If you are up for trying as with

 https://xraypy.github.io/xraylarch/installation.html#installing-the-development-version

let me know if this is still happening for you.

[rarivera10]

Everything appears to be working well for me now. Will update if I run into the issue again. Thanks for the fix!
