OK it also took me some time to figure this. First: you need to plot your image first, then use add_scale Second: add_scale expect a value (unitless) which is expressed in the same unit as the plot. Can you try:

test = spm.SXM(test_file).get_channel('[P8]_Lockin_X')
test.show()
test.add_scale(1)
plt.show()
