custom style of line series in chart area

[Gui]

I want to show data using RadChart which is dynamic and has multiple line series. And also each series has  its own style depending on its value (in my app, I want to show nornal and dash lines in chart area). But I have the problem that in chart area, it can set only one style lineseries(normal or dash) but I want to show both. So anyone can suggest me how to do this.

Thank you

Hello Gui,

Take a look at the attached sample. It shows how to create two Line Series where one of the lines is dashed. To be able to show Line as dashed you should create custom Style (as shown in the attached project). This help topic explains styling via Styles in more detail- http://www.telerik.com/help/wpf/radchart-styling-and-appearance-styling-chart-series.html.
The chart is bound using  a list of business objects. In order to map to such kind of business objects, you have to create a new instance of SeriesMapping. Each SeriesMapping has ItemMapping property. For each ItemMappings the following properties are set - DataPointMember and FieldName which specifies from where the data should be taken. You can find more information about this in our help article -

All the best,
