[Solved] XAxis interval by 1 month

Hi,
We are using Rad Charts for silverlight Q1 2013, I have a requirement where we have to show data for 1 day, 1 week,  1month and 365 days [1 year]. I am able to achieve all the intervals otherthan 365 days where I have to divide X-Axis steps by 1 month.        
Could you please let me know, if this feature can be achieved with the version I am using. I will have to show data in dd MMM yyyy format like 01 Jan 2012, 01 Feb 2012...... 01 Jan 2013 e.t.c.,                     Thanks in advance

Hi Sowjanya,

Please, use RadChartView for Silverlight, which is designed to handle this scenario. Depending on the specifics you can use DateTimeContinuousAxis or DateTimeCategoricalAxis. Please, find more details in this help topic.

Hi Ves,
  Thanx for replying. At this point of time, I can't change my chart Since there are other data intervals, bounded to the same chart. I somehow managed to achieve this by first dividing steps by 30 days and changing label to the desired date in the layout updated event, Code snippet attached.

double thirtyDays = 720 / 24d;
  radChart.DefaultView.ChartArea.AxisX.Step = thirtyDays;

if (selectedInterval == EMIntervalEnum.One_Year)
                {
                    // Looping to Cutomize label
                    for (int i = 0; i < houseConsumption.HouseConsumptionChart.DefaultView.ChartArea.AxisX.TickPoints.Count - 1; i++)
                    {
                        radChart.DefaultView.ChartArea.AxisX.TickPoints[i].Label = HouseConsumptionData[i].TimeStamp.ToString("dd MMM yy");
                    }
                }
