Creating charts from multiple tables

[#1]

Hello,

I'm using one scheme that contains multiple tables.

I would like to create charts with information from many tables all together, but when I do it, the display that I get s empty.

How can I do it?

Thank you.

Could you show us some data and/or your script?

Something tells me that data is either not ending up in your data model or that the data in the key fields does not match.
