Thank you Omar that helped to get outline of my line chart and now I am able to have two spark points at start and end point. But when I implemented this I ran into some other issues.
1) Can we fix the label hover as shown in below image and disable rest of the hover from march 17 to jan 18.
If i am pointing my mouse on feb 17 then I am getting two hover values of risk. One for Red dot and other for blue line.(63 & 63). I want only red dot hover value and rest of them I want to disable. Any option to do that in qlik sense.
