Hi,
The easiest way is to loop over all the columns using a script:
int numcols = wks.ncols;
for (ii=2; ii<=numcols; ii++) {
smooth iy:=Sheet1!$(ii) method:=sg npts:=4 polyorder:=2 oy:=Sheet2!<new>;
}
Highlight the entire script in the script window and hit enter to run it. The script above assumes you have your input data in Sheet1, with X data in column 1, and n Y data columns to the right. The output data is sent to Sheet2, and will create a new X for each. If you only care about generating new Y columns, the following will work:
int numcols = wks.ncols;
for (ii=2; ii<=numcols; ii++) {
smooth iy:=Sheet1!$(ii) method:=sg npts:=4 polyorder:=2 oy:=Sheet2!(<autoX>,<new>);
}
Regards,
Vince |
