Savefig

When I use ramanspy.plot.peaks it's returns an axes.

ax = ramanspy.plot.peaks(preprocessed_spectrum, prominence=0.08)

ax.savefig('test.png')

AttributeError Traceback (most recent call last)
c:\Users\Maria Clara\OneDrive\Área de Trabalho\MAC\Raman\5A.ipynb Célula 12 line 1

AttributeError: 'Axes' object has no attribute 'savefig'

How to transform ax in a figure?

[dgeorgiev21]

Thank you for reaching out!

The plotting functionality of RamanSPy is built upon matplotlib.

In matplotlib, you can save Figure objects, but not standalone Axes objects.

One way to work around that is as described here:

ax = ramanspy.plot.peaks(preprocessed_spectrum, prominence=0.08)
ax.get_figure().savefig('test.png')

I have left this issue open since the method ramanspy.plot.peaks (as well as ramanspy.plot.spectra and ramanspy.plot.mean_spectra) should ideally take an Axes object(s) as an optional argument(s) to allow better control over the plotting of figures and subfigures. Then, creating and saving a figure would look like:

fig, axs = plt.subplots(...)
ramanspy.plot.peaks(preprocessed_spectrum, prominence=0.08, ..., ax=axs[...])
fig.savefig(...)

Any contributions are more than welcome!
