CFCHARTSERIES seriesLabel not showing on Chart

I am using CFCHART in CF10 to create a basic line graph that will have one or more series'(lines) displayed on it.  Each line is a different color and I'd like to label each line so that the user knows what each graphical implementation of data it represents(i.e. blue for series 1, red for series 2 etc).

I am having no luck getting the label to show despite trying every single possible combination of attribute/label possible.  What am I doing wrong?

<CFCHART name="my_graph" chartheight="150" chartwidth="475" format="png" showborder="no" showxgridlines="no" showygridlines="no">

<CFCHARTSERIES type="line" color="Red" seriesLabel="Test Label">

<CFCHARTDATA item="2010" value="1000" />

<CFCHARTDATA item="2011" value="2000" />

<CFCHARTDATA item="2012" value="3000" />

<CFCHARTDATA item="2013" value="4000" />

</CFCHARTSERIES>

</CFCHART>

Shouldn't serieslabel show on the graph?
