Dimensions
It's important to know that a dimension in CCC is not an MDX dimension. Here it is represented by a subset of atoms. When you want to achieve more advanced results, you can change the behavior of CCC. Well maybe I shouldn't say change the behavior, but help CCC behave in a different way than the default behavior. What we can do is change one dimension, but not change the rest of them; CCC will apply the default options to just those dimensions. Don't forget that these changes are optional and you only want to apply them to change the default behavior of CCC.
When dimensions are not defined, the default dimensions, with the default options, are generated to satisfy the needs of the chart. Anyhow, the data dimensions can be explicitly defined. When defining dimensions, you can define them partially. You will be able to define just one and let the others be automatically generated.
The list of dimension options is defined at: http://www.webdetails.pt/ctools/ccc/charts/jsdoc/symbols...
