John,
Thanks for this trick - that's smart. Anyway I think I should explain
bit more about what I'm planning to do as your solution does not solv
this completely.
What I'm planning to do is to create a kind of a custom map, let say o
Europe, that will show the potential of countries.
The potential is calculated by a pivot table from a raw data. Pivo
table is very flexible enabling me to select both countries and year
of comparison (to be precise years are more important than countries a
countries do not change much in Europe

so we may always display jus
all of them). This is also user friendly as it alllows the user t
change the year without understanding all VBA and raw data processin
that is in background. Moreover the pivot chart data is still linked t
the raw data, so once I add, correct, change the raw data I hav
automatically chart updated.
I have thought about having pivot bubble chart as I can set am Europea
map in the backgound of the chart and then use constant X, Y value
that will correspond with the coutries placement on the map. And th
potential will be displayed by the bubble size.
What a surprise when Excel told me that I may not use the bubble chart
So now coming back to your solution.
My pivot has years in rows, countries in columns and potentia
parameters on pages.
Yes, I may take the bubbles size from the table and make regular char
out of it. And below I set two rows with fixed XY positioning.
The pivot tables button allows me to change years and the char
updates. Unfortunately at the same time, if the user change th
countries, the chart will corrupt - the pivot will change, the XY wil
remain constant.
I may not block or hide country button only. If I hide all the button
I won't be able to specify the years
At the end of the day I may instruct the user: "DON'T CHANGE TH
COUNTRIES", but in my experience it does not work :-(
Eh, why Microsoft has blocked bubble chart with pivot.....
So now with much more knowledge, how would you fix it?
Thanks,
Micha
