Flex line charts: baseAtZero

baseAtZero... this little property helped save me a lot of code. The client didn't like that the charts were sometimes so squished because the charts always started at 0 but none of the data was close to the zero range. I was going to loop through the data in each chart and set the min and max... but then I discovered this property.


<mx:verticalAxis>
<mx:LinearAxis id="vaxis" baseAtZero="false"/>
</mx:verticalAxis>


All it does basically is stop the chart from forcing the vertical axis start at 0, and therefore starts it based on the data.
