Hi everyone,

is it possible to set the 'substitution level' for an existing label via labtalk? I only found ways to do this while creating a label, not when modifying an existing one.

'Substitution level' is available via right-click, then programming control, and then setting 'Link to (%, $), Substituion' to 1, 2,... This was called differently in older versions of Origin.

Origin Ver. and Service Release (Select Help-->About Origin): 8.6.0G SR3, Operating System: Windows XP

Regards,
Johannes

I couldn't find a LabTalk means of doing this, but here is an OriginC function you can use:

void SetLevel(string strObj, int iLevel)
{
GraphLayer gl= Project.ActiveLayer();
if(gl.IsValid())
{
GraphObject go = gl.GraphObjects(strObj);
if(go.IsValid())
{
if(go.GetObjectType() == "Text")
{
Tree tr;
BOOL bRelative = TRUE;
tr = go.GetFormat(FPB_ALL, FOB_ALL, TRUE, bRelative);
tr.Root.LinkToVars.nVal = iLevel;
go.ApplyFormat(tr, TRUE, bRelative);
}
else
printf("%s is not a Text object.\n", strObj);
}
else
printf("%s is not a valid object in active layer\n",strObj);
}
else
printf("GraphLayer not active.\n");
}

For example, with a graph active and a layer with the Legend active, you can shut off substitution with:
SetLevel(Legend,0)
and turn it back on with
SetLevel(Legend,1)

Thanks a lot, it works.

BTW, is there a document describing the use of the different substitution levels? 0=off, 1=on, 2=? ?

Johannes
