Many elements and attributes have been added or renamed since the 4.0 version of PCXML. Changes and additions are indicated in paranthesis next to the appropriate element or attribute.
To maintain backwards compatibility, PopChart Builder saves appearance files in the PCXML 4.0 format by default. Unless you change this behavior, you will be unable to take advantage of many of the latest PCXML features.
You can change the PCXML format that PopChart Builder uses to save its appearance files by selecting Edit > Preferences > Save and checking the Save Using Latest PCXML Format box. However, be aware that you cannot use appearance files saved in the latest PCXML format with previous versions of PopChart Server. The current version of PopChart Server supports previous versions of PCXML.
If you are manually creating your PCXML documents, be sure to specify the version of PCXML you are using by setting the Version attribute of the Chart tag. This ensures that PopChart Server will properly parse your PCXML.
