I am having issues with the 'alpha' option. This file works fine on my work computer, but crashes matlab on my laptop and I am stuck overseas and desperate! Looking at the problems other users had with 'alpha' maybe it's something to do with opengl?
Thanks for the quick reply, Dee. My data is wavelength reflectance data which is equally spaced from 350-2500nm, so my sampling interval is in nm. On running your suggestion, it appears the scaling itself was apparently not the issue - the data points are sampled 1nm apart, but I want to smooth at the level of 26nm. Is that possible with some call to this function, or what would I need to use something else?
