[EpiData-list] help

Hello, I'm in the process of learning how to use EpiData Analysis. I'm going through the instructions in the Tiramisu example. I've run into a problem. I'm trying to create the epicruve/histogram. The graph window (Editing Chart) is not showing up. I looked through comments on the [EpiData-list] and found a recommendation: insert (set graph edit=on) in the command line. I tried this but received this message (graph edit not supported). How do I turn on the (editing chart) window?

Thanks,

Sandy
