Any idea how to do that? My code is like this: void AutoPlot(int ncol) { Worksheet wksData; // Declare Worksheet (Layer) object Column col; // Declare Column object int iColNum; string strColName; wksData = Project.ActiveLayer();// get the active layer, which is the fitted worksheet for (iColNum=1;iColNum<=ncol;iColNum++) { // *** Use Worksheet class Columns collection to get second column and check column name *** //col = wksData.Columns(iColNum); // Get second column in worksheet (0 based index) //strColName = col.GetName(); // Get column name to check (just for fun) //creat a graph GraphPage grphData; bool bRetG = grphData.Create("PCH2"); // use the "PCH2" template for graph // Point to active layer in current graph page GraphLayer grphLayer = grphData.Layers(); // Declare a curve object using x,y columns of worksheet Curve crvData(wksData, 0, iColNum); Curve crvFit(wksData,0,iColNum+ncol*2); // Plot data curve to active layer int nPlot = grphLayer.AddPlot(crvData, IDM_PLOT_LINESYMB); int mplot = grphLayer.AddPlot(crvFit, IDM_PLOT_SCATTER); grphLayer.Rescale(); } } Thanks a lot Yu [/quote]   Check here to include your profile signature.
