Chart error (Invalid parameter)

[Alvin Bruney [MVP]]

Line 3 is failing with an invalid parameter exception. I understand that the
chart utilizes the regional date settings but my date settings are verified
and set to MM/dd/yyyy and my short date format shows up as 04/05/2004 after
a reboot.

Commenting out the groupingunit and groupingunittype lines results in a
successful graph being rendered. Have I possibly overlooked something?

object[] strCategory = {"04/05/2004","04/11/2004"};
string strValue = "291,359";

objChart.Axes[ChartAxisTypeEnum.chCategoryAxis].GroupingUnitType =
ChartAxisUnitTypeEnum.chAxisUnitMonth;
objChart.Axes[ChartAxisTypeEnum.chCategoryAxis].GroupingUnit = 1;

//Add a series to the chart's series collection
objChart.SeriesCollection.Add(0);

//add labels
objChart.SeriesCollection[0].DataLabelsCollection.Add();
objChart.SeriesCollection[0].SetData (ChartDimensionsEnum.chDimCategories,
(int)
ChartSpecialDataSourcesEnum.chDataLiteral, strCategory);

objChart.SeriesCollection[0].SetData (ChartDimensionsEnum.chDimValues,
(int)ChartSpecialDataSourcesEnum.chDataLiteral, strValue);

thanks

I have seen in other posts that it is apparently necessary to set
HasPlotDetails to true before getting the category axis to recognize
timescale. However, I cannot get this to work. Have you done this in
your code?

Let me know if it works for you. I posted a question about this to
this group, but did not get a response.

Thanks.

The issue is that the grouping function family can only be applied after the
axis has been loaded with data, not before.
