What's New in DXperience v2009 vol 3
DXCharts for WPF
Support for Common DevExpress WPF Visual Themes
In previous versions, DevExpress Charts for WPF maintained its own set of styles defining the appearance of points, borders, shadows, and other elements. With this release, we've added support for standard DevExpress WPF themes. This change allows you to create visually consistent applications when using DevExpress WPF controls. If your application’s theme is modified, DXCharts used within your application will be automatically synchronized to match all DevExpress controls used within the project.
Empty Points
Much like the XtraCharts Suite, DXCharts is now capable of processing data points that don't have a corresponding series value. This often takes place when you have several characteristics to measure and measurements are carried out against slightly different argument sets. Though arguments differ slightly, you can still store these measurements within a single data table and compare them in a single chart. Empty points are displayed either as gaps or as missing bars and points, depending on the series type.

Axis Enhancements
The following axis-related improvements have been introduced in v2009 vol 3:
- Axis Titles. You can now display text next to chart axes.
- Reversed Axes. Toggling this option for any 2D axis will change its direction, so that all corresponding series are also mirrored.
- Templates for Axis Labels. You can fully customize the appearance of axis labels.
Custom Draw for Series and Series Points
Two newly introduced custom draw events allow you to modify individual Series and Series Points. For example, the following image demonstrates how to change bar and label color based upon the current series point value.

SeriesPoint.Tag Property
You can now associate any arbitrary object with a series point by placing it into the Tag property. The important fact here is that if you bind a chart to data, you don't need to manually fill the Tag property for all series points. By default, this property contains a reference to the underlying data object (e.g. DataRowView) which corresponds to this series point. This feature is invaluable when creating drill-down charts, and also when it's necessary to display custom information for every series point in a legend.

True Date-Time Value Axis
Previously, only numerical Y-axes were supported. With v2009 vol 3 release, you can also display charts with date-time values, as shown below.
