Hi,

I am using RadChart for Silverlight 5 and in my chart series i am creating 4 stacked Bar series and a 3 line series runtime in code behind.
I am able to change the Stacked Bar series color.But i am unable to change the color of line series which is alos created in the sam chart control, it is taking the default color only.
Can you please to suggest me a solution to resolve the problem.

I have pasted my code as below for your reference.
private void LoadPlannedChart(Collection<WcfServiceRef.DSR_ProgressData_BO> lstPlannedChartData)
        {
  
            try
            {
                RadChart1.SeriesMappings.Clear();
                var lstlegend = lstResultData.GroupBy(cm => new { cm.ActualDailyExecutionrate, cm.AverageOriginalTargetDailyExecutionRate, cm.AverageRequiredDailyExecutionrate },
                                                        (key, group) => new
                                                        {
                                                            key1 = Convert.ToDecimal(key.ActualDailyExecutionrate),
                                                            key2 = Convert.ToDecimal(key.AverageOriginalTargetDailyExecutionRate),
                                                            key3 = Convert.ToDecimal(key.AverageRequiredDailyExecutionrate)
                                                        });
  
                // RadChart1 = new Telerik.Windows.Controls.RadChart();
  
                SeriesMapping PlannedseriesMapping = new SeriesMapping { LegendLabel = "Planned" };
                PlannedseriesMapping.SeriesDefinition = new StackedBarSeriesDefinition() { ShowItemLabels = false, ShowItemToolTips = true };

Hi,

I reviewed the code, and it looks correct. However, based on the supplied information, it is hard to determine why the style settings are not applied. To further trace the issue, it will be best if you open a formal support ticket, and send us a small working example, demonstrating your setup. I will review it locally, and advise you further. Additionally, you may want to review the other alternatives to styling the series, outlined in this article:
