show condition for chart

[#1]

Hi,

In my current app's having two charts one is "LineChart" and second is "ScatterChart".

Now what i am trying to reach is

When i select the data point value that lied in LineChart then it should display the scatterchart.

It should not be like while selecting the caption of the linechart or anyother other place in linechart object, displaying the scatterchart. That should strict condition like when selecting datapoint value lied in linechart then only scatter should display.

Ex: in attached image, if user select any value that having in linechart like 0.013636 or 0.009091 or 0.0004545.... then only should display the scatter chart.

how can i work on it ?

Thanks & Regards
