[Erp5-dev] Where is Resource_getInventoryHistoryChart?

[Łukasz Nowak]

Hello,

I was trying to play with ZGDChart and PyChart widgets, but only
example I found is on Delivery_viewInventory form, but there is no
Resource_getInventoryHistoryChart in ZODB, and simulation tool refer
to it.

So:
- where is it?
- how may I play with above widgets?

Thanks,
Luke
