Hi, 
  
We have just upgraded from V3.1 to V3.7 and noticed a difference on the bubble chart.  The size of the bubbles are based on the values on the Z data, which we  have the same values for Z, but the bubbles' sizes are way bigger than before.  Is there a way to make a fix size for different bubble values?  In our case, we have five different sizes for bubbles: 
  
value                       size 
<5M                         2 
>5 M  <10M             4 
>10M <15M             8 
>15M <20 M            16 
>20M                        32 
  
Can we make a fix size for each of the value above?  Apparently the Fusion chart now is randomly adjusting the bubble sizes for us.  In one chart, we have 2 set of  Z values: < 5 M, and >5M  <10 M.  In the 3.1 version, the bubble sizes are ok, however in the v3.7, the bubbles are huge.  
  
It will be nice if we can always have a constant size for each bubble size.  Please advice.
