Graph Legend question

One short question:

when using the Legend command for a graph, is it possible to skip a selected trace on the graph from appearing in the legend?
I have always a certain wave on a graph which I would like not to appear in the legend ...

I hope the question makes sense ...

Thanks!

It can be done only programmatically. Here is an example:
Function AddLegend(graphName)
    String graphName        // "" for top graph
   
    if (strlen(graphName) == 0)
        graphName = WinName(0, 1)   // Top graph
    endif
   
    String list = TraceNameList(graphName, ";", 1)
    String legendText = ""
    Variable numItems = ItemsInList(list)
    Variable i
    for(i=0; i<numItems; i+=1)
        String item = StringFromList(i, list)
        if (CmpStr(item,"wave1") == 0)
            continue            // Skip this trace
        endif
        String itemText
        sprintf itemText, "\\s(%s) %s", item, item
        if (i > 0)
            legendText += "\r"      // Add CR
        endif
        legendText += itemText
    endfor
   
    Legend/C/N=MyLegend/W=$graphName legendText
End
