Andy asks:
Dear Jedi. How can I get the legend to show up on the right of my pie chart. It seems perpetually stuck at the top. I'm using cf7 (and will upgrade to 8 in the next few months).
There is no direct way, but once again, the Chart Editor that ships with ColdFusion comes to the rescue. I loaded it up, selected a Pie chart, and edited the Legend property. I selected Right alignment, and took the generated XML. Now the XML I got had a few extra elements, but I stripped it down to this:
<?xml version="1.0" encoding="UTF-8"?>
<pieChart>
<legend placement="Right"/>
</pieChart>
All together, the code then is:
<cfsavecontent variable="style">
<?xml version="1.0" encoding="UTF-8"?>
<pieChart>
<legend placement="Right"/>
</pieChart>
</cfsavecontent>
<cfchart format="flash" show3d="true" style="#style#">
<cfchartseries type="pie">
<cfchartdata item="Like Pacman" value="75">
<cfchartdata item="Not like Pacman" value="25">
</cfchartseries>
</cfchart>
Here is a screen shot of the default pie chart followed by the modified one. As you can see, the colors change a bit too, but if you don't like the colors you can tweak that as well.

You can also, of course, save the xml as a separate file and reference it in the style attribute to apply the same styles to multiple charts.
Yep - and you could get fancy. You could create an XML block for left aligned - note the differences - and generate the XML on the fly to go back and forth.
Hey Ray,
Where could one find this Chart Editor that you speak of?
Under your coldfusion folder, charting, webcharts.bat.
Thanks I found it after reading the docs a little more carefully. :)
Is this a CF8 only thing? When I try to pass a string to the style attribute, I get an error: "The system cannot find the file specified".
Nope, CF7 added it. Don't forget the PDF reference manual shows the history of tags back to MX.
