Multiple Series Binding to Charts

[Adwait]

I have an object that I have some data in. The object has the following properties

Description
Amount
Date

I want to plot a chart where Date would be in X axis and Amount will be on Y (which is easy). If I just set the ItemsSource and the X and Y properties, this works fine.

However for each distinct description I want to show a new series. But I want to keep this dynamic. so if there is Series 1 and Series 2 in Description, then only two would show, if there is more than 2 then all would show. How is this doable?

Hi Adwait,

You have opened this thread with the old RadChart as a product. We suggest you do not use it, but use the new ChartView instead. It is much faster, it resolves many of the limitations of the old charting component, it is very flexible and easy to set up.

It seems that you require grouping functionality, where a single items source is grouped into several objects, where each object has a Key the Description, and an associated list of items. The chartview does not provide grouoing capabilities out-of-the-box.

I think that the best way to go here is to declare an additional property in you view model SeriesModels which hold the grouped data. You can then use a SeriesProvider which will dynamically create as many series as SeriesModels you have.

Hello Adwait,

The ChartView is part of our wpf suite and Silverlight suite. The ChartView is not a control, it is a code name for a set of controls - RadCartesianChart, RadPolarChart, RadPieChart and ChartDataSource. Do look at the provided links where you will see this in work.
