Origin Ver. and Service Release (Select Help-->About Origin): Origin 8.6
Operating System: Windows 7
How can I differentiate multiple Y columns? I am not good at executing labtalk scripts, so an example script to put into the command line would be very helpful.
Thanks in advance. |

Hi davidandersoniii,
As you are using Origin 8.6, you can use the "Repeat This Analysis" method discussed at:
http://www.originlab.com/forum/topic.asp?TOPIC_ID=10768
Although above page is regarding the Smoothing, differentiation is the same thing.
Does it work as you like?

Sorry, It's actually 8.0724. I tried what you recommended, but when I left click that column, nothing happens. The repeat analysis option is not available.

Hi davidandersoniii,
Here is a sample script, which can take care both designation patterns of XYYYY.. and XYXYXY...
nc=wks.ncols;
inc=1; //Default pattern XYYY..
if(nc>=3) {if(wks.col3.type==4) inc=2;} //Detect XYXY...
for(ii=2; ii<=nc; ii=ii+inc) {
//smooth iy:=wcol(ii) method:=aav npts:=4; //Smoothing
differentiate iy:=wcol(ii) order:=1; //Differentiate
}
Tip: Here "differentiate" is the name of x-function for differentiation. ("smooth" is for smoothing.)
I don't remember the names of all x-functions, but it is easy to get - when you press the small triangle button at
the upper right corner of analysis tool, choose "Generate Script" flyout, then you get the corresponding script
(x-function) command based on the options you chose in the dialog box in the Script window. (Please see the screenshot.
Here "-r 2" is a general option to set the recalculation mode, 1=Auto, 2=Manual, 0=None).
Once you get the command name, you can learn the detail options from "Help: X-Functions" menu.
Hope this is helpful.
