Problem with sum spectra for bruker M4 tonado .BCF file

[Divyadeep00]

import hyperspy.api as hs

import scipy
# Load your data (replace with actual data loading code)
data = hs.load('MS-1b_S.bcf')
data= data[4]
data.plot()
roi = hs.roi.RectangularROI(left=110, right=125, top=55, bottom=65)

s_roi = roi.interactive(data, recompute_out_event=None, color='C1')
s_roi = roi(data)
roi_sum = hs.interactive(s_roi.sum, recompute_out_event=None)
roi_sum.plot()

I am using above code to view the spectrum at my roi, while doing so, I encounter a flat XRF spectra shown in image

both orange and red are nearly (even when they overlap) the default eds signal navigator gives a spectrum but the sum plot is giving a flat signal, is it a but or I am doing something wrong.

By any chance, do you have any NaN in your data? If so, you should use https://hyperspy.org/hyperspy-doc/dev/reference/api.signals/BaseSignal.html#hyperspy.api.signals.BaseSignal.nansum

but if the reason is the NaN value than default view eds viewer should also show flat, but it is showing signals

[ericpre]

No, the default pointer doesn't take the sum.

[Divyadeep00]

but the provided image both have same pixel, size, default pointer is giving values but sum pointer not, as you can see in the provided image also.

[Divyadeep00]

in this image both pixcel is overlap

Have you tried to use nansum instead of sum as suggested above? e.g. try to adapt your example above to use roi_sum = hs.interactive(s_roi.nansum, recompute_out_event=None).
