Hi,
I don't know anything (yet) about making or even using scripts, so I hope someone is willing to help me with the following:
I want to perform a Savitzky-Golay smoothing on all the Y-data in my worksheet (sharing one X-data column) and create a new worksheet with the same X-data column and the adapted Y-data columns. Can someone write a script, tell me how to use it and where I can alter the smoothing parameters if necessary?
Thanks a lot!

Hi Pythe,
This script will duplicate and smooth the active worksheet using SG method. Results will go to the duplicate wks. To execute... copy all lines to the script window, adjust polydeg and pts as desired, then select all lines and press Enter.
polydeg=3; // polynomial degree (1-9)
pts=2; // number of pts to smooth on right and left
%I=%H; // name of active wks
win -d; // duplicate
doc -e W {%R=%H}; // find name of new wks
curve.polydeg=polydeg;
curve.smoothleftpts=pts;
curve.smoothrightpts=pts;
curve.smoothpts=2*pts+1;
curve.x$=%(%I,1);
loop (i,2,wks.ncols) {
curve.data$=%(%I,i);
curve.result$=%(%R,i);
curve.SGSmooth();
};
win -a %R; // active results
