Multiple Lines on a line chart.

[Saaed Bhatti]

How can I show multiple lines on a line control? They way I have it setup, it showes all the lines but draws them all based on the last data provided.

basically this is what I have

foreach

 

(var item in coll)

 

{
 

 

SeriesMapping seriesMapping = new SeriesMapping();

 

 

ItemMapping itemMapping = new ItemMapping();

 

 

ItemMapping itemMapping2 = new ItemMapping();

 

 

// StackedSpline Chart

 

seriesMapping =

new SeriesMapping();

 

seriesMapping.SeriesDefinition =

new StackedSplineSeriesDefinition();

 

seriesMapping.LegendLabel = pt.PlanName;

itemMapping =

new ItemMapping();

 

itemMapping.DataPointMember =

DataPointMember.YValue;

 

itemMapping.FieldName =

"Count";

 

seriesMapping.ItemMappings.Add(itemMapping);

 

 

ItemMapping itemMapping3 = new ItemMapping();

 

itemMapping3.DataPointMember =

DataPointMember.XCategory;

 

itemMapping3.FieldName =

"Name";

 

 

seriesMapping.ItemMappings.Add(itemMapping3);

 

 

this.chartPlanCaseCount.SeriesMappings.Add(seriesMapping);

 

 

 

 

this.chartPlanCaseCount.ItemsSource = item;

 

}

Hi Saaed Bhatti,

It seems that for all the SeriesMappings you add an ItemMapping for YValue with FieldName set to "Count", so you will get all the series showing the data from the "Count" property/column.

Just a side note -- you can move the ItemsSource assignment outside the loop.

Hey Ves,
Thanks for your response.

If I want to show 6 series, won't have i have to set the itemsource 6 times as well? How will it map the data to the series being drawn on the map?

Thanks
Saaed.

Hello Saaed,

You can find a thorough description of the databinding capabilities provided by RadChart here: http://www.telerik.com/help/silverlight/radchart-populating-with-data-data-binding-support-overview.html. I think you will find it useful.
