Hi all,
I got a chart with LineSeries, on which data can be shown properly. Now I want to add 2 lines as threshold. When the users look at the chart they can see easily data under the lower threshhold line is safe, data between two threshold lines means warnning, data hight then the higher threshhold line is dangerous.
For example, all of the data is between 20 and 120, I want to draw the threshhold lines at 53 and 68. How to do it?
Thanks!
