Qt Chart: Getting Intersection Point of multiple qlineseries and a vertical marker line on mousemove event

[abhishek.cs006]

Hello All,

I am implementing Qt chart application where i have multiple Qlineseries Graphs with mutiple Y axis. I have a vertical marker which moves on mouse move event along x axis. ( X axis is common for all lineseries).

I want to get the intersection point of vertical marker and qlineseries graphs so that i can retrieve the y axis value for each graph.

Please Help me.

Thanks
