I have one container, in that it has two object(bar chart, and line chart), and my need is "When I select the any value from the Bar chart, it will activate the second line chart"
Not using containers. It's possible to hide the bar chart and show the line chart when you select a value in the bar chart. You can use the Conditional Show option on the Layout tab of the properties window of the objects. The expression you need can make use of the getselectedcount function.
