Steps to Reproduce:

Errors on the following code:

	<cfchart
		format="png"
		xAxisTitle="Organisation code"
		yAxisTitle="Hits"
		scaleFrom="0"
		scaleTo="#vTopScale#"
		gridlines="#vChartLines#"
		chartWidth="539"
		chartHeight="#vChartHeight#"
		seriesPlacement="stacked"
		backgroundColor="EFEFEF"
		dataBackgroundColor="EFEFEF"
		rotated="yes">
		<!--- disabled to prevent 'Comparison method violates its general contract! null <br>The error occurred on line 1.' errors --->		
		<cfchartseries type="scatter"
					query="XXX" 
					itemColumn="AAA"
					valueColumn="BBB"
					seriesLabel="Usage limit"
					seriesColor="cc0000"
					paintStyle="light"
					markerStyle="diamond">
				<cfchartseries type="scatter"
					query="XXX" 
					itemColumn="AAA"
					valueColumn="CCC"
					seriesLabel="Usage limit over #numberFormat(val(vTopScale), '_,___')#"
					seriesColor="336699"
					paintStyle="light"
					markerStyle="rcross">
		<cfchartseries type="bar"
			query="XXX" 
			itemColumn="AAA"
			valueColumn="DDD"
			seriesLabel="Total usage hits"
			seriesColor="808080"
			paintStyle="light">
		</cfchartseries>
	</cfchart>

I'm not able to provide a full test case as it appears to depend on the underlying data which I'm unable to supply. Removing certain rows or cfchartseries appears to resolve the error, but I can't work out exactly what's causing the problem

Actual Result:

The error above

Expected Result:

No error and displaying the chart

Any Workarounds:

None
