Hi, with the following function i try to add another Plot to an existing Graphpage:

void addplot(string graphname, int plottyp, int MYFORM, int SYSCOLOR, Worksheet *ptrwks, int x1, int y1, string curvelabel)
{
PageBase pb = Project.Pages(graphname);

// Überürüfung ob ein solches Fenster existiert.
if( !pb.IsValid() )
{
printf("%s is not a valid window\n", graphname);
return;
}

GraphPage gp = pb;
GraphLayer gl = gp.Layers(0);


// DataRange für plotten der Messdaten
DataRange grafikdata1;
grafikdata1.Add(*ptrwks,x1,"X");
grafikdata1.Add(*ptrwks,y1,"Y");

int iPlots = 0;

foreach(DataPlot dp in gl.DataPlots)
{
iPlots++;
}
//printf("%d\n",iPlots);

int nPlotIndex = gl.AddPlot(grafikdata1, plottyp);
nPlotIndex = 1;

Tree tr0,tr1;

tr1.Root.Symbol.Size.nVal = 3; // Size of symbol
tr1.Root.Symbol.Shape.nVal = MYFORM;

GraphObject go = gl.GraphObjects("Legend");
go.Text = go.Text + "\n\l(" + (iPlots+1) + ")\c"+ (SYSCOLOR+1) + "(" + curvelabel + ")";

DataPlot dp1 = gl.DataPlots(iPlots);
dp1.SetColor(SYSCOLOR,TRUE);

bool bRet;

if( 0 == dp1.UpdateThemeIDs(tr1.Root))
{
bRet = dp1.ApplyFormat(tr1, true, true);
//printf("Done\n");
}

if(nPlotIndex >= 0)
{
gl.Rescale();
}

}

It does adding a Plot in the right color and edits the legend correctly, but the dp1.ApplyFromat doesnt work. It just changes the symbol to an right arrow.

Can you change the line
DataPlot dp1 = gl.DataPlots(iPlots);

to 
DataPlot dp1 = gl.DataPlots(nPlotIndex);


I assume you want to change the format of the added plot.
