Hello, I've added some code so that when you open a 1D spectrum and it creates a window (because there is no existing compatible one) then it ought to make a more sane determination of the y axis range. So currently it just used -10^6 to 10^6 and for Varian data, for example, that is woefully wrong. Now it will determine the min and the max of the spectrum and make the range a bit bigger than that. But if you then open subsequent 1D spectra in that window then it doesn't adjust the range further. Perhaps we need a shortcut so that one can "fit spectra in window" for 1D spectra. Wayne
