How do I hide the box/border surrounding the title in a cfchart? Can that be done with attributes or does it need to pull from an xml style file? The showBorder="yes"/"no"...doesn't seem to have any affect?
Correct - showBorder is for the chart as a whole. And like (almost) always - the chart editor comes to the rescue. Click the Title value in the chart editor opens up a sub editor with a butt load of options for the title:
Notice the style attribute on the right? That handles the border around the title. You can set it to a variety of different styles or just select "None" to get rid of it. The generated XML is:
<title> <decoration style="None"/>Poop </title>
You can also play with the other styles and tweak the color too if you want.
