While integrating Fusion Charts with AwareIM, support has helped me learn how to use a rule to put an apostrophe in a Plain Text attribute.
For example, I needed to build the following in an attribute:
<set label='2004' value='37800' />
By using the ` above the ~ on the keyboard, the following rule accomplished the desired result:
BOname.result=<set label='
+BOname.label+' value='
+BOname.NbrValue+' />
I hope this might help shorten the learning curve for others.
