Unable to plot nanometer axis in spectral profile plot

[Former user]

Hi, I have been trying to plot spectral profiles from various multi and hyperspectral images with ENVI and GEOtiff file types. The band number x axis works fine but as soon as I try to plot spectra with the Nanometers axis no plot is drawn and I get the following error message :

AttributeError: 'QComboBox' object has no attribute 'timeseries' 
Traceback (most recent call last):

Version de Python : 3.9.2 | packaged by conda-forge | (default, Feb 21 2021, 05:14:22) [GCC 9.3.0] 
Version de QGIS : 3.18.0-Zürich Zürich, exported 

The wavelength centers informations (with the wavelength unit) are indeed present in the HDR files and are correctly identified by QGIS (same for GEOtiff).

I tried to modify the corresponding python script to print the error-making attribute and all I can confirm is that QComboBox does have a timeseries attribute.

Finally, I have reinstalled the extension and now I do not have any errors poping, but still no plot is drawn :

I currently am on a linux mint distro with QGIS 3.18 beeing installed as a conda package in a separate conda environment (maybe it is relevant ?).

Thank’s, I can confirm the issue!

A fix that works for ENVI files is remove the timeseries variable as an input to the _wavelength method in line 326 in rdpprofileplotwidgetbase.py.

Original lines 323-326:

xvalues = self._wavelength(layer=layer,
    modeRaster=profile.ui.axis().ui.modeRaster().isChecked(),
    modeTimeseries=profile.ui.axis().ui.modeTimeseries().isChecked(),
    timeseries=profile.ui.axis().ui.date().timeseries())

change to:

xvalues = self._wavelength(layer=layer,
    modeRaster=profile.ui.axis().ui.modeRaster().isChecked(),
    modeTimeseries=profile.ui.axis().ui.modeTimeseries().isChecked())

Unfortunately, this does not work for me. A fix would be nice!
