Displaying Subscripts with Custom Graphs and Tables

Hi

1. Is there a shortcut way of displaying all subscipts within a custom graph and/or table without having to define each combination individually?

2. Can you have more than 6 variables/subscripts in any one graph or table, and if so how do you add variables?

Many thanks
