Limiting values displayed in a bubble chart

[Anonymous]

Can the values displayed in a bubble chart limited?  I have the following bubble chart:

I need to reduce the number of bubbles in the chart.  I have tried 'Dimension Limits' which i think is not the the way to do it.  Let's say i want to show the top 10 values per dimension, what expression can i use for this in the calculated dimension? Can anyone assist?

Regards.
