Exploding pie example, please...

[scott]

I was excited to read about the interactivity feature that lets you explode a pie slice -- Is there an example somewhere ?

Thanks

Hi Scott,

You can review our "First Look" example and the "Interactivity" one also.

That was great.  I added 3 lines of code and it all just works.  One question:  How can I tell from the chart area click handler which pie slice was clicked - is there a selected item attribute hidden away somewhere ?   Is there some way I can iterate the datapoints in a series and determine its clicked (exploded) state ?

Thanks -

Hi Scott,

Unfortunately, such public API is not introduced with our Q2 version. We will deliver it with the Service Pack. We aim to achieve a more complex approach to allow selection through binding and through code.

We will be glad if you provide more information about your scenario in order to to have it in mind when we improve the interactivity feature.
 
Best wishes,

Hi Sia...  My compliments to your team on your responsiveness and great controls. 

I am implementing a sequence of charts that display the distribution of certain events - say people reporting getting a cold.  There can be any number of related details about the person (continent, country, family size, marital status, whatever).  There can be N charts displayed.  The charts are managed by a CategoryManager that also manages a datagrid displaying the details.  When a chart area item gets clicked in any chart the CategoryManager gets notified so it can update the datagrid.  It would be really cool if the CategoryManager could:

foreach (Chart chart in myCharts)
{
    DataPoint dp = chart.SelectedDataPoint;
    if (dp != null) {
        string columnName = (string) chart.Tag;
        dataGrid.FilterBy(columnName, dp.LegendLabel);
    }
}

Are these links still valid?
All I get is a blank page.

Hi Wayne,

  You are correct, the links point to an older version of the demos. If you go to this link, you will find a blog post about the migration towards RadChartView.

This is the link that will bring you to the online demo of the old version you're looking for: RadChart > First Look

Good luck,
