Multiple Y Items Per X Item

[James]

Is the relationship between X and Y items on a chart 1 to 1?

I have data that looks like this:

Cnt      Date               Week
1         09/23/2009     09/20/2009
1         09/24/2009     09/20/2009
4         09/25/2009     09/20/2009
11       09/28/2009     09/27/2009

I am doing a line chart and would like to have two "X" items from the data above: 9/20/2009 and 9/27/20009. The 9/20/2009 x item would have the three appropriate Y entries. Is it possible to group Y items into X items in this manner?

Thanks.

You can have multiple y-values per x-value. How you implement this is kind of up to you, but to define this all manually you could do:

ChartSeriesItem mySeriesItem = new ChartSeriesItem();

ChartSeries myFirstSeries = new ChartSeries();

mySeriesItem.XValue = x;

mySeriesItem.YValue = y; myFirstSeries.Items.Add(mySeriesItem);

Also, since you are using dates I would recommend looking into this demo since it deals with numerical representations of dates on the axis.

Cool..thanks much, Schlurk.
