I have 2 questions.
1.
I made Drill-down-chart.

that chart rises 2 tooltips.

maybe, One is the default tooltip(Yvalue-label).
Another tooltip is graph.

I want to only graph tooltip.
What must I do?

2.
and SomeTime,I Clicked the value and then are moved to a different graph.
but Tooltip of the previous graph does not disapear.
I use WCF.(maybe, some delay)
I want to remove tooltip.
What must I do?
