Display real time data on Intensity Graph

I am using measurement studio 2015 WPF version. My requirement is to display real time data on a intensity graph . I used uint[,] to store the data and set datasource through binding. When I refresh the data , chart is flickering always .

1. How to avoid flickering effect while updating new data ?

2. what is the best way to display live data on a IntensityGraph ?

Thanks,
