Hello!
Another that I have is this: Is it possible to override the zooming action so that the actual zoom doesn't happen (i.e. chart stays as it is), but instead a list of the points within the zoom window is returned, so that they can be filtered out to create a separate report on them?
Hi,
Please see: http://community.infragistics.com/forums/p/44025/242600.aspx#242600
Hope this helps!

Before I proceed on this, I have a question: will it be possible to highlight somehow the points selected? Currently in our charts we highlight them with blue, but as I have read elsewhere on this forum that with XamDataChart it's not possible to style individual points. So, is that possible, and if yes -- how would I do it?
Any ideas?..
The simplest way would be to engineer it such that the data items had the series color in a property, unless they had a property directly set on them.
For example, if they had one property called ActualBrush, and one called Brush. ActualBrush could check to see if Brush was null and return the value for the series if so, Otherwize the value of Brush. And then you would bind to ActualBrush rather than Brush.
There are other ways to achieve this too, although they would require a bit of a more complex setup. In WPF you could use a PriorityBinding, but I don't believe you have access to that in Silverlight.
Well the data items (read: points) do have a Color property in them. The question is -- how do I access the serie color from inside the point?
OK, so there seems to be no easy way... But how about assigning colors to the series -- is that possible? Like, create a set of random colors and assign them to the series one by one?
Sorry for the delay in reply. You can see which brush a series is using by inspecting ActualBrush.
You can explicitely set the color a series should use by setting its Brush property.
Alternatively you can set the Brushes collection on the chart, to set the series of brushes that the chart should chose from in order to assign to the series in the chart.
There are many ways you could go about this. You could have a back reference from each data point to the series, or to the collection that contains them which could have a reference to the series. Or you could populate a default color property on each item with the color you expect the series to have or that you will manually assign to the series.
But how can I get access to the serie from datapoint, if I assign a list of datapoints to the series' ItemsSource?
