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.

Regards,
Ivan
