Hi,
Delphi 5.
I'm working with National Instruments ActiveX controls and specifically
their CWGraph.ChartY function.
I'd like to chart two traces but I can't figure out how to make up a two
dimensional array to pass to the function.
Here's what I have to plot one trace:
ClippedArray : array of Variant; // Definition.
...
ClippedArray := VarArrayCreate([0,SAMPLE_SIZE],varVariant); //
Creation.
...
ClippedArray[k] := data; // data added to array.
...
FilteredDataGraph.chartY( ClippedArray ); // Data displayed on chart.
Since National Instruments doesn't really support Delphi I can't find
anything that points me in the right direction.
Any suggestions?
Thanks
John
