Plotting Problems

[LuisG]

Did you look at the Measurement Studio examples?

I did it.

I change the function to plot and so I post here the solution.

Now, it works and it plots in real time mode as many chart as I want.

                    GetObjHandleFromActiveXCtrl (panel, control, &ObjHandle);
                    CA_VariantSet1DArray (&dataToPlotY, CAVT_DOUBLE, numberOfTraces, arrValue);
                    CWUIControlsLib__DCWGraphChartXvsY(ObjHandle,NULL,CA_VariantDouble (timestamp),dataToPlotY,CA_VariantBool(0));

I will try to set the chart options now, like the multi scale mode and everything else. I will post here some examples.

Does someone know how to do it?

Thank you in advance.

You can also look at an open-source real-time plotter called LiveGraph. Its functionality os very similar to what you need. See http://www.live-graph.org.
