DateTime values on X axis

[javier]

Hi there,

I have a RadChart which one I use to represent discret double values.
So I create as many ChartSeries as I need and I added items -by using ChartSeries.AddItem(Value, String) -.
For my need, every single value added to the ChartSeries has a corresponding DateTime value, so I need to add DateTime values to the X Axis.

The problem is that while I create the ChartSeries I can't add a DateTime value, a ChartSeriesItem  only has double on X and Y axis.

I also tried to add the DateTime x axis values by using the RadChart.PlotArea.XAxis.AddItem(Date.ToString()), but that makes no sense because only recieves string, not DateTime values.

So how can add a DateTime value to the X Axis which match a value at the ChartSeries ?

And hoh can add a ToolTip to the  ChartSeriesItem?, I tried ChartSeriesItem.ActiveRegion.Tooltip  but I don't see it, so I think it does not work.


Thanks a lot,

Hello javier,

In order to set DateTime as value, please, use DateTime.ToOADate(). Also, note, that you need to set
RadChart.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.LongDate;

You are correctly setting the tooltip and it should be working. Please, provide more details on thie issue so that we can further assist you.
