  • 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.
