Hi,

I have a need to have a movable slider on line charts. The way it should work is as follows:

1. Slider/Cursor should be parallel to Y-axis i.e. vertical axis

2. When user moves this slider, corresponding/intersecting Y values on all graphs show up in labels just like a stock ticker chart.






Thanks,
