Amita, in this situation, it is most likely going to require that you post a sample app with your data model and chart with expressions etc. It does not have to be the full set of data, but enough that folks will be able to see how the data model is setup and what you are doing with the expressions. Not sure you are going to get what you need otherwise on this one, as it is a bit difficult to follow without being able to see the other detail. Just wanted to try to move things forward for you. If you have some confidential fields, you can use the Settings\Document Properties\Scrambling tab to scramble those, but if any of those fields are being used in your expressions, that may prove problematic as well.
