    Hi,

     I'm trying to build chart with real time data, where I display some values with a StepLineSeries, and this works fine. However, I want to display the Moving Average of those values as well, and for that I'm using the MovingAverageIndicator but it doesn't work. 

     If I display all the data at once the MovingAverageIndicator works just fine but, if I try to display it with the data being added in real time it doesn't work. Is this some limitation of the indicator or am I doing something wrong?

     Best regards,

    Diogo Duarte

    Hi Diogo,

    It seems that the live data scenario is not handled by the chart's MovingAverageIndicator. I logged an item related to this behavior in our feedback portal. I also updated your Telerik points. 

    To update the data points of the indicator you can reset its Period property when a new item is added in the ItemsSource. For example:
    // add new item
     
    var indicator = chart.Indicators[0] as MovingAverageIndicator;
    var period = indicator.Period;
    indicator.Period = 0;
    indicator.Period = period;

    I hope this helps.
