I have created a
QCustomPlot line graphs containing multiple
QCPAxisRect which share a common margin (makes them aligned) and aligned vertically.
I have a requirement that I need to draw a vertical line across all the line graphs (i.e. the axis rects) when the mouse hovers hover any one of them i.e. a vertical line will move horizontally based on the mouse's x-position. I have overriden the
QCustomPlot and looping through all the
QAxisRect and adding a
QItemLine with appropriate x,y position. Now, the problem is that I only get the line for the first axis rect, not on any subsequent graphs. How do I make it appear on top of all the rects and not just the first one?
Also, I have to show the a axis value beside the line as a text label. For this, how do I get the x-axis value from x-coordinate ?
