I would like to display delta of the two in bar chart.

How do get the delta of result1 and result2 on the chart.

Here is the codes:

<cfchart format="flash" xaxistitle="respondents" yaxistitle="numbers" style="#style#" show3d="yes">

<cfchartseries type="bar" serieslabel="result" >
<cfchartdata item="result1" value="75">
<cfchartdata item="result2" value="80">
</cfchartseries>

</cfchart>

Thank you,

Do you have an idea of how you would 'draw' the delta?

I wanted the delta value to display as labels inside the bar chart.
Can I do that? Thank you.

So to be clear, item 2's label would have the delta between 1 and 2. 3 would be 2 and 3. And item 1 would have no delta.

Right

Yes, as result 1 = 75 and result2 = 80 and delta should display on result2 5 delta.

As far as I know, this is not possible in the Flash style charts in ColdFusion 9. It may be possible in ColdFusion 10 with the HTML based charting, but you would need to use JavaScript to modify the labels dynamically.

Another option would be to use a second series. Like a bar chart of deltas.

How can I make the horizontalbar chart thicker.
