Yet another basic question.
What is the labtalk command to graph a simple function on an existing plot?
This would be the equivalent to the menu selection of
Graph->Add Function Graph
I want to plot that same function on every open plot window which I assume I can accomplish with the "doc" command.
Just digging into LabTalk and working my way up the learning curve.
Help/hints appreciated.

Mike, again my thanks. Very helpful and more to the point - you taught me more than I asked. Appreciate the time you took to answer the post - I've already incorporated NewFunction into my script and all is well.
Now on to the next challenge ...

Hi Carl,
To find out what the Add Function Graph command does...
> Open the script window.
> Press Ctrl+Shift and select Graph->Add Function Graph
In my Origin 7 SR4 the following shows up in the script window...
Menu id=36120
NewFunction
So one way to run the command is with
menu -e 36120;
That works fine, but menu IDs can change from one version to the next. A more reliable way is to execute the command itself: NewFunction. The syntax for running a section in a script file is run.section(File,SectionName), so NewFunction must either be a macro or an Origin C function. If you open the Programming Guide, go to the Index and type in NewFunction an entry for the NewFunction macro shows up with this definition...
Def NewFunction {
doc -cs F;%B=F$(count+1);create %B -f 10;
def ErrorProc [del %B];set %B;del -m ErrorProc;
};
doc -cs F;// count the number of datasets with names beginning in F. result is saved in the variable count.
%B=F$(count+1); // create a new function name
create %B -f 10; // create a new function with that name and give it 10 rows
def ErrorProc {del %B}; // what to do if the next command results in a command error. (delete the function.)
set %B; // open the plot details dialog for the function
del -m ErrorProc; // clean up
You can use the NewFunction macro in you labtalk script or just use the particular commands that are appropriate for what you want to do.
Hope that helps.
