I have a xy scatter chart with 5 series. Is it possible to have the line
thickness dynamically change when selected? An example is, if you click on a
line you can use the up and down arrows to cycle threw the different parts of
the chart. When scrolling I would like the thickness to change, while select,
and when I go to the next line return to standard formatting.

I know this sound a little out there, but just trying to make the boss
happy. Thank you for your help.
