Another date formating issue

i want date appear in mmm-dd format - keep getting full odbc date format

my query:
<cfquery name="monthlychart" datasource="2onboard">
select distance, time, walkdate
from bockwalk
where month(walkdate)=#month(now())# , year(walkdate)=#year(now())#
</cfquery>

my cfchart:
<cfchart format="swf"
style="/xml/dailydistancegraphs.xml"
chartheight="175"
chartwidth="575"
showlegend="no"
showborder="yes"
show3d="no"
foregroundcolor="000000"
scalefrom="0"
yaxistitle="mileage">
<cfchartseries type="bar"
query="monthlychart"
valuecolumn="distance"
itemcolumn="walkdate"
seriescolor="ff0000">
</cfchartseries>
</cfchart>
