Hi Arthur,
If you are okay to do manually, you can follow the Yuki's way. If you want to do programmatically,
you can run the following simple script when the graph window is active. /////////////////////////////////////////////////
layer -b s -2; //if plots are grouped, and layer can have offset plots
doc -e DY { //loop over plots
range rp=%C; //data range of the picked plot
y_offset=-1*rp[1]; //Offset is the 1st value of the curve
//y_offset=-1*min(rp); //if you want to set the minimum in curve as offset
set %C -sy (y_offset); //if you want to set offsets without data change
//rp=rp+y_offset; //instead, if you want to update the source data
}
layer -ax; //rescale Y axis
/////////////////////////////////////////////////Note that this script works only when the plots are grouped, and won't change the original data,
but only presents plots with offset.
Hope this helps.
