The page hangs in the introduction.
It may be lack of any requirement on my machine?

Must be like a Pop up

Thank you!

Hello Natália,

Can you please revisit the page, and confirm whether the exception persists, or you are able to access the example as expected. It may have been a temporary issue, since the page is working as expected on my end.

Kind regards,

Ok ..
I can now access.

However, I would like the chart to be viewed in another window.

Thanks...

Hi Natália,

The additional data is shown in a tooltip - can you please specify if you need this to be in a separate window, or if you have another behavior in mind. Any additional information will help me better address the question at hand.

Sincerely yours,

Hello

I need it in a separate window.
Where I can insert buttons to export the contents, for example.

Thanks

Hi Natália,

Most of the logic in the example to which I referred previously, is handled in the following method:

private void ChartItemToolTipOpening(ItemToolTip2D tooltip, ItemToolTipEventArgs args)
       {
           RadChart chart = new RadChart();
           chart.Height = 200;
           chart.Width = 300;
           chart.DefaultView.ChartLegend.Visibility = System.Windows.Visibility.Collapsed;
           chart.DefaultView.ChartArea.AxisX.LayoutMode = AxisLayoutMode.Inside;
           string axisItemLabel = RadChart1.DefaultView.ChartArea.AxisX.TickPoints[args.ItemIndex].Label;
           chart.DefaultView.ChartTitle.Content = string.Format("Quarterly Preview: {0}", axisItemLabel);
           chart.DefaultView.ChartArea.AxisY.DefaultLabelFormat = "C";
           DataSeries series = new DataSeries();
           series.Definition = new LineSeriesDefinition();
           series.Definition.ShowItemLabels = false;
           SeriesExtensions.FillWithSampleData(series, 4, (int)args.DataPoint.YValue);
           string[] quarters = new string[] { "Q1", "Q2", "Q3", "Q4" };
           for (int i = 0; i < chart.DefaultView.ChartArea.AxisX.TickPoints.Count; i++)
               series[i].XCategory = quarters[i];
           for (int i = 0; i < series.Count; i++)
               quarterlyRevenues[i] = series[i].YValue;
           chart.DefaultView.ChartArea.DataSeries.Add(series);
           tooltip.Content = chart;
       }

Essentially, instead of showing a tooltip with the data, you can open a window:

http://demos.telerik.com/silverlight/#Window/Silverlight/PopupManager

which can contain additional information on the chart.
I hope this gets you started properly.

Thanks Yavor,

It is possible another chart within that window?

[Yavor]

Hi Natália,

Indeed, you can dynamically create the control:

and add it to another container. Let me know if any specific issues arise.
