SreeJonn -
Here is an example for setting the ToolTip FormatString of the X-axis
to 4 digitis, scientific notation. This code piece is in C#, but
the expression is nearly the same syntax in VB.
//turn on tooltips
scatterPlot1.ToolTipsEnabled = true;
//4 digit scientific notation
scatterPlot1.ToolTipXFormat = new FormatString(FormatStringMode.Numeric, "e4");
For the y-axis, the method is scatterPlot.ToolTipYFormat. For
information in regards to the FormatString Class format options, you
can consult the 'NumberFormatInfo Class' in the .NET Framework Class
Library help.
I hope this helps in your application development. Have a great day!
