AddPlot(curve,IDM_PLOT_SCATTER)

Plot types are defined in oPlotIDs.h. These are the common types...

#define IDM_PLOT_LINE 200 // Line
#define IDM_PLOT_SCATTER 201 // Scatter
#define IDM_PLOT_LINESYMB 202 // Line+Symbol (perhaps your symbol size was 0?)
#define IDM_PLOT_COLUMN 203
#define IDM_PLOT_AREA 204
#define IDM_PLOT_HILOCLOSE 205
#define IDM_PLOT_BOX 206

But if you are using Origin 7, plot types are defined in the file OC_const.h

Yes, the definitions were moved in Origin 7.5 but haven't changed. The ID numbers are the same as those used with LabTalk's "worksheet -p" command.

I don't think there's an Origin C method for changing the symbol size so you need to use LabTalk (set -z)...
void SetSymbolSizes(int symbolSize)
{
	GraphLayer gl = Project.ActiveLayer();
	string strCmd;
	
	foreach ( DataPlot dp in gl.DataPlots )
	{
		strCmd.Format("set %s -z %d;",dp.GetDatasetName(),symbolSize);
		gl.LT_execute(strCmd);
	}
}

You can also try something like the following ...


bool SetSymbolSize(int SymbSize)
{
	GraphPage gP=Project.Pages(-1);
	GraphLayer gL=gP.Layers();
	if(gL.IsValid())
	{
		DataPlot dP=gL.DataPlots(-1);
		Tree tR;
		tR=dP.Curve;
		tR.Symbol.Size.nVal=SymbSize;
		dP.Curve=tR;
		gP.SetShow();
		return (true);
	}
	return (false);
}
