[Ruth]

Hi,

Is it possible to have a drill down option for  horizontal bar chart in WPF ?

If yes please provide me the sample code.

Thanks,
Ramya

Hi Ruth,

I have attached a sample project that demonstrates how you can achieve this using RadCartesianChart (which is part of RadChartView). The project includes a generic view model class, which can be used as a base for implementing drill down scenarios. The requirements are that your data should be hierarchical and that each class representing items of a given level should implement the ITreeNode interface.
For example of how to provide data to this view model, you can look at the TestDrillDownChartDataSource.cs file along with the TestDrillDownClassHierarchy.cs file. There you will find a classes that represent:

• Sales for a particular Continent
• Sales for particular Company from a particular Continent (each Continent has a list of Companies)
• Sales for a particular car Model, manufactured by a particular Company
• And an enumeration representing the different levels of this hierarchy

To use the GenericDrillDownChartViewModel class, you need to provide the top level ItemsSource, DataPointBindings for each drill level, functions that return the next and the previous member of the DrillLevelEnum (so the view model know which binding to choose) and finally the start drill level.

I hope this helps!
