CF11 CFChart pie, labelformat="percent" not displaying % - coldfusion

Question

How do I display a % with the value. labelForms="percent" doesn't seem to work, its clunky adding it to the item, am I missing a way to format it?:
<CFSET PercentLocked = 0>
<cfset PercentUnlocked = 0>
<cfset PercentOpenQueries = 0>
<cfset PercentOpenErrors = 29>
<cfset PercentClean = 71>
<cfchart
type="pie"
chartWidth="800"
show3d="true"
font="times"
style="blue"
labelformat="percent">
<cfchartseries >
<cfchartdata item="Locked Forms (#Percentlocked#%)" value="#PercentLocked#" >
<cfchartdata item="unLocked Forms (#PercentUnlocked#%)" value="#PercentUnlocked#">
<cfchartdata item="Forms w/Open Queries (#PercentOpenQueries#%) " value="#PercentOpenQueries#">
<cfchartdata item="forms w/Errors (#PercentOpenErrors#%) " value="#PercentOpenErrors#">
<cfchartdata item="Clean forms (#PercentClean#%)" value = "#PercentClean#">
</cfchartseries>
</cfchart>

Googling led to this ZingChart example involving the "plot" attribute. According to the ZingChart pie chart docs, several "tokens" are supported for use in customizing the text/values displayed
%npv - The percentage value of the pie slice (node) relative to the entire pie (sum of all nodes)
%t - The text of the current plot, pulled from the text attribute in the plot/series object
This example displays both the item text and value (as a percentage):
TryCF.com Example
<cfset plot = { "value-box":{
"visible":true,
"placement":"out",
"text":"%t (%npv%)"
}}>
<cfchart
type="pie"
chartWidth="800"
show3d="true"
font="times"
style="blue"
plot="#plot#">
<cfchartseries >
<cfchartdata item="Locked Forms" value="0" >
<cfchartdata item="UnLocked Forms" value="0">
<cfchartdata item="Forms w/Open Queries" value="0">
<cfchartdata item="forms w/Errors" value="29">
<cfchartdata item="Clean Forms" value = "71">
</cfchartseries>
</cfchart>
