adding dynamic lines or quadrants to bubble chart?

[griff]

hello!

I have a bubble chart which I'm trying to add lines (or coloured squares)
to, so I can group the bubbles into 4 defined-by-cell-value parts of the chart

Currently I have 2 lines crossing the chart which I have to manually move if
values change (they should each cross the axis at the weighted average point)
but as the chart is going to be made into multiple versions I want to
automate as much as possible

I did see Mr Peltier's guide for adding dynamic quadrants to x-y charts (I
don't mind if the bubbles are segmented by rectangles either!) but couldn't
find anything showing me how to do it with bubbles - any ideas?

using XL 2003

Many thanks in advance for any assistance!

Unfortunately bubble charts cannot be combined with other chart types. You
can use custom-sized markers (e.g., large and small circles) for the points
of an XY chart with area or column chart backgrounds:

But this is not natively dynamic. You would have to use VBA and some kind of
event procedures to make the bubbles update when the data changed.

Thanks Jon for the reply - I may not be able to build the chart as I was
asked to, but at least now you've told me it can't be done I need not waste
any more time searching for the magic solution in Excel!

cheers
