How about this:
//Create a legend for all plots
legend -s;
//Set the legend text
legend.text$="\l(1) description for plot 1
\l(2) description for plot 2
\l(3) description for plot 3";

Hi Oliver:
The help file didn't list all of the object properties, however, you can type
legend.=
in the command window to show the properties for legend object. So to position the legend and add border, try the following scripts:
legend.x = value of x coordinates
legend.y = value of y coordinates
legend.background = 1; // Add border

I'm working on a legend myself, however I am trying to use data from a worksheet to insert into the legend (each worksheet processed has a metadata tag on it). The number of worksheets are variable, and so it has proved rather difficult. So far I am doing something along these lines:
loop (jj, 1, fileCount)
{
%J = Sheet($jj)_J;
%K = %J\l;
}
...(and further down)...
// create the legend
legend -s;
legend.text$ = %K;
legend.background = 1; // add a border
Which obviously does not work. I am finding it difficult to get to grips with the way Origin manipulates strings. Is there a way of doing this that works so that it remains in the same format and there are not too many changes to the rest of the script?

Hi Andrew:
The syntax to specify a legend that includes data sets from a layer is:
\L(LayerNumber.DataPlotNumber,DataPointNumber) DataPlotName
For Example:
\L(1) Data1_B
means the first dataset of the current layer, and name it Data1_B. So may be you can change your scripts as:
loop (jj, 1, fileCount)
{
%J = Sheet$(jj)_J; // Note that $() is used for numeric to string conversion;
%K = "\L($(jj)) %J"; // Need to quote the string because there is space between \L($(jj)) and %J;
}
.....
// Create the legend
legend -s;
legend.text$ = %K;
legend.background = 1;

Thanks for the reply Larry, however when using the code that you provided me instead of getting "1239123_JUL_04_2006_10_20_39" which is an example of the meta-data, I simply get "Sheet1_J" on the legend.

Oh and the code you gave me is also over-writing the contents of %K on each pass so that instead of having several legend metadata tags, I have only one... the last one processed.

Bump.
Does anyone have any idea why this is happening?
Is it not possible to append to a variable in Origin?

Hi Oliver,

%K is overwritten by the line %K = "\L($(jj)) %J". If you want to append to previous %K try this...
%Z="";
loop (jj, 1, fileCount)
{
%J = Sheet$(jj)_J; // Note that $() is used for numeric to string conversion;
%K = "\L($(jj)) %J"; // Need to quote the string because there is space between \L($(jj)) and %J;
if(jj==1) %Z=%K;
else {
%Z=%Z
%K;
};
};
.....
// Create the legend
legend -s;
legend.text$ = %Z;
legend.background = 1;

I am still getting Sheet1_J (Sheet2_J, Sheet3_J, etc.) instead of the contents of Sheet1's J column cell 1 (Sheet2's, Sheet3's, etc.).
Should I be quoting %K = Sheet$(jj)_J; in any particular way? The data is alphanumeric if that helps. Probably with underscores too. Is %K able to manipulate non-numeric data like this?
Also the legend formatting leaves preceding tabs for each new line, is there a way to control this formatting?

Sorry, but this is the first time you've indicated that you want the contents of a cell rather than the column name. Use this...
%J=Sheet$(jj)_J[1]$;
Each new line will start with a plot symbol rather than a tab. If you don't wan't a space between plot symbol and the next letter just remove the space between \L($(jj)) and %J...
%K = "\L($(jj))%J";
...If you don't want a plot symbol just use %K=%J.
