How do I change the label text in a legend directly from labtalk? For each column pair to be plotted, I wish to construct a legend string using a subset of text from the first entry in each column (a text entry) rather from the column name. For example, I extract current density Jval and x,y color coordinates xval, yval for the column pair and want to make a legend string that says something like

"Current Density = $(Jval) mA/cm\+(2), x = $(xval),y = $(yval)"

Is there an object method for doing this? I have tried making my own legend using the label command, eg

label -sa -j 0 \L(1) str1 \r\n \L(2) str2;

where str1 and str2 are the new strings as constructed above, but this doesn't quite line up as well as legend.

Any ideas? I'm running Oring 6.1 right now. Thanks!

The legend is merely a text object named "legend". You can access its contents with

%S=legend.text$;

Similarly, you can set its contents with

legend.text$=%S;

where the string variable %S can be anything you want. I'm not sure if you can use escape characters (\n, \r, etc.), by you always use the method I suggested in the Simple MessageBox topic to create multiple lines of text.

Thanks Mike. The legend object is not documented very well for us newbies. I also found a link on the Origin forum (not labtalk - silly me for not searching everywhere) that shows how to make legends with long strings.

Another way that I found to be even easier is to just put the string in the column label before making the legend. You know, something like (for column number ii):

%z = mystring;
mysheet!wks.col$(ii).label$ = %z;

I don't know why I didn't start using column labels earlier to do this. It is easier to give each column a descriptive label than trying to deal with the 11 character column name limit.

Sorry, but for some reason when I posted this topic it got posted twice. I really don't know how it happened.

Cheers!
