Hi:

I'd like to calculate values (e.g. RMS or mean) of regional selected data. Is it possible to use LabTalk script to perform it?

Are there any commands such as:
a = rms(____); (____= the red selected region)
a=



Thank you.

Hello,
We support range notation to specify a range in worksheet, graph, etc.
https://www.originlab.com/doc/labtalk/guide/range-notation
Also we have many built-in functions to use in Labtalk
https://www.originlab.com/doc/LabTalk/guide/Functions#Built-In_Functions

E.g.

range aa=[graph1]layer1!1[10:20];
ma=mean(aa);
ma=;



Thanks, Snow

Hi Snow,

Thank you for the reply.

I wonder if I can select the region I want graphically (using Regional Data Selector), and then calculate the values of the selected region?

In other words, does range notation support graphically selected region?

Thanks,

Hello,
%C refers to current plot. If there is selection, it will refer to that as well

So u don't have to define range.
Just do
ma=mean(%C)
