c# and Excel Charts

[R102oy]

I am trying to programmitically add some functionality to excel chart that I
am creating, one thing I am trying to do is to have the tool-tip/bubble show
up for every time series being plotted by moving the mouse in the x-axis of
the chart(line chart). Say I have 3 time series data and I created a line
chart, so X-axis is a time line and say y-axis is share price, we will have
three lines for 3 time series, if I place the mouse on any one time series,
it gives me information about that point of that time series(with a pop-up or
tool tip, I heard people are calling it bubble), it doesn't show me anything
about the other 2 time series at the same point. I want to be able to see
that tool tip/bubble for all the 3 time series as I move my mouse along
x-axis.

Does anyone have any code snippets or direct me where I can get help
regarding this.

Thanks
