[flexcoders] How to increase the font size of CategoryAxis labels

[anewgene]

Hi, Group,
    I have made a BarChart to display data with many categories 
(~90). 
I have the verticalAxis as a CategoryAxis. The label for each 
category 
is too small to be readable with the default. How can I force 
increasing the font size for these labels? I notice that there is 
still 
some empty space between labels to allow larger font size without 
overlapping. I searched manual and this forum, but cannot find the 
answer.

The below is my code for "verticalAxis"

<mx:verticalAxisRenderer>
    <mx:AxisRenderer axisStroke="{axis_stroke1}" showLine="true" 
showLabels="true"
         tickPlacement="none" canDropLabels="false" labelGap="0"/>
</mx:verticalAxisRenderer>
<mx:verticalAxis>
   <mx:CategoryAxis
        categoryField="sample"
   />
</mx:verticalAxis>


Thanks in advance.
