plotting individual path after fitting #417

Closed duoduoss closed 1 year ago

duoduoss commented 1 year ago

Dear @newville :

I was trying to plot each individual path after EXAFS fitting using Spyder. The "plot_paths_k" and "plot_plaths_r" commands didn't work with error message "'FeffitDataSet' object has no attribute 'pathlist'". In the script, I have a "pathlist" or "paths":

"dataset= feffit_dataset(data=thisgroup, pathlist=[ path1, path2, path3], transform = trans)"

The function "plot_chifit(dataset)" works well. If I use "plot_chir" or "plot_chik" to plot the "dataset.paths['path name']", i got the calculated one but not the fitted.

I am wondering how I can fix this, and also whether it is possible to export the fitted chik and chir of individual path for plotting.

Thanks you very much

@duoduoss If you are asking for help with something you did that is not working as you expect, you sort of have to explain what it is that you actually did that is not working as expected. You did not post any such code. You set up a dataset. Apparently you did a fit. And.... I don't know.... something else?

There are lots of examples and fitting with XAS Viewer actually generates a fitting script.

Post actual code of what you did.
