Hi Wenli & Shen, Many thanks for your quick reply. I will try your suggestions.
Just to re-iterate our chart will be a mix of 2 colors (green and red) where the red bars will be very less in numbers. Example if there are 100 data points coming in from a stream 2 or 3 will be in red as they will exceed a threshold value on Y-Axis (lest say 90%). Hope that makes my query clearer.
