Hi,
I have a graph with multiple spectra on it and wish to smooth all the curves in the graph. How do I do this without having to go through the curves one by one? I'm not overly keen on programming in C but will if it's the only way.
Thanks,
Jim |

This wiki shows how to choose the method and modify the options:

For any of the new XFunctions, you can get help by typing:
name -h
or
help name
in the Command Window or Script Window.
As in
smooth -h

Hi Shirley,
Thanks for the script. The script runs and creates new 'smoothed' plots but the plots are only smoothed fractionally. Is there a way to specify which smoothing method is to be used (i.e. Savitsky-Golay, FFT filter) and the point of window in the script?
Thanks,
Jim |

Hi Jim,
Origin cannot smooth multiple curves at one time From GUI.
You can copy the following script to command windows and execute it.
int n;
layer -c;
for (n=1;n<=count;n++)
{
smooth iy:=!$(n);
}
Please make sure that the graph window is active when you execute the script.
