Hello,

I need to replace a letter in several text objects in multiple graphs. All labels I'm interested in share a partial name, which is Temp (Temp1, Temp2, etc.).

This would be the script for 4 labels:
loop (i,1,4)
{

string name$ = Temp$(i);
string lab$ = %(name$).text$;
lab2$ = Substitute(lab$,°,º,1)$;
%(name$).text$=lab2$;

}
}

Which works. My problem is, the number of TempX labels is variable, so I would need a way to count how many there are to tailor the loop command.

I think it should be relatively obvious, but I have been unable to find out how.

Thank you.

Please refer to this page to loop over all graph objects:
https://www.originlab.com/doc/LabTalk/guide/Looping-Over-objs#Looping_Over_Graphic_Objects

And your code can be:

doc -e P
{
    doc -e LW
    {
        doc -e G
        {   
            if(left("%B", 4)$ == "Temp")
            {
		%B.text$ = Substitute(%B.text$,°,º,1)$;
            }            
        }
    }
}

Sorry, my mistake. I did look into doc -e command (several times, actually) but totally missed G option.

Thank you, this works flawlessly.
