How to crop a spectrum?

[nicocopez]

Is there any way I can crop a spectrum in ramanchada2?

[nicocopez]

I see one possibility would be to do the following (see code below). However, it only works for spe.x and spe.y, but I would get an error if I do spe[condition]. So I could go on working with spe.x and spe.y as numpy arrays, but then I would miss all the advantages of working with spectrum class.

## Cropping
low_end = 580
high_end = 600
condition = np.logical_and (spe.x >= low_end, spe.x < high_end)
plt.plot(spe.x[condition], spe.y[condition])

Thank you Georgi! That worked nicely

Yes, we have such a method in RC2 -- trim_axes
One can specify boundaries in 'x-axis' units or 'bin' index via method parameter.

This example should do the same as yours (unless i have a typo):

low_end = 580
high_end = 600
spe_cr = spe.trim_axes(method='x-axis', boundaries=(low_end, high_end))
spe_cr.plot()

My original answer was as a reply to the second comment. I am posting it again so that it can be marked as an answer
