Thanks for Demo and Quick Response.
Your given solution is working from our side and made demo as per our requirement (http://jsfiddle.net/oh2gs300/10/)
But, We have some question to implementation some features. so can you please help us to resolve it.
1. How can we show Threashold line in Legend with title like (Recall, Preceision etc. in demo)
2. How can we set Title for X axis. we tried to put (facetAxis: { title: { enabled: true, text: 'Trainning Sets'}}) but all the X value gone.
3. How can we stop drildown in chart (when we click on chart, everytime it drilldown in it.)
4. How can we change Line Type for different series (Dashed, Solid, Dotted etc..)
