Origin(1)

I have just begun using Origin in processing experimental data.
Good software!
Here is the example showing how to smooth the data and reset the origion(zero point) by averageing adjacent points.
acturally this is using the X-function.

ii=1;loop(ii,1,4) { smooth iy:=($(ii)) method:=aav npts:=60 oy:=(,$(ii+4));};a=col(5)[1]; col(5)=-(col(5)-a);a=col(6)[1]; col(6)=(col(6)-a);a=col(7)[1]; col(7)=-(col(7)-a);a=col(8)[1]; col(8)=-(col(8)-a);
