Dashboard

So i have been testing this and got it working but just curious how the dashboard gets populated ? I have already created few categories for both expenses and income but they do not show up on the Income by Category or Expense by Category dashboard ?

What about the Cash Flow on the Dashbard ? mine is empty. What triggers for this to populate properly ?

Thanks for your help

You should try to create some invoices/revenues and bills/payments.

I actually have, I have a few entries. I am mainly using payments and revenue. I do not use Invoices or Billing.  It still shows empty, something i am missing
