Does anybody have a routine to turn scatter plot points "on" or "off" on a
chart using, say, a mouse action, that would grab the point and put it into
a second series, thereby changing the color and/or symbol? This would be a
great benefit to removing outliers when adding trendlines.

I've tried writing a little VBA , but didn't get anywhere since I can't seem
to get Excel to identify the X-Y point locations outside of the actual values
(row-column would be better) which, if you deal with 10,000+ pairs doesn't
help much.

Thanks for any help in advance.
