Origin 8 SR4

Hi there,

working more and more with this very useful DataRange class which simplifies a lot, I now could isolate a little problem:

I would like to plot Y data against X data coming from a different row range:


Worksheet wks("Book1");
DataRange dr;
dr.Add("X", wks, 0, 0, 9, 0);
dr.Add("Y", wks, 10, 1, 19, 1);
	
GraphPage gp;
gp.Create("Origin", CREATE_VISIBLE);
GraphLayer gl = gp.Layers();
gl.AddPlot(dr, IDM_PLOT_LINE);
gl.Rescale();


It seems that OriginC takes the row range of the Y data, ignoring the one specified when adding the X data.

Is this is limitation, bug, or my mistake? However, it would be a great feature getting this done. Thus, one could save a lot of storage needed for duplicated data collected in additional worksheets.

Thank you for having a look at this problem,

Michael

Thank you for your quick response. This would be really great! Most of our application projects consist of collecting different data from different worksheets which cannot be plotted directly (because of formatting reasons or data manipulation like reduction or simple calculations). Since DataRange has such a good perfomance we use it quite often (in earlier OC days we added a temporary worksheet containing redundant data only for graph creation). Adaption of the plotting code would make this tool even more convenient.
