BubbleChart: y-axis expands to huge values when yaxis:max is not set

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open the attached file chart-bubbles.html
2. Open the attached file chart-bubbles-200.html

What is the expected output? What do you see instead?
The output from chart-bubbles.html should be relatively similar to what is seen 
in chart-bubbles-200.html.  The only difference between the charts is that 
chart-bubbles-200.html restricts the y-axis maximum to 200.  The y-axis maximum 
in chart-bubbles.html should not be up as high as 700,000,000 as the largest 
y-value in the datasets is 184.7.

What version of the product are you using? On what operating system?
Tested with flotr r301 from flotr-svn, Firefox 6.0, Google Chrome 13.0.782.112 
m, Google Chrome 15.0.855.0 canary, on Windows 7 x64.
