Dashboards: where to start?

Good day

I have Dashboard in the menu, but where do I start to set it up?

This might help get you started: https://codereview.tryton.org/269771002/diff/259731002/doc/index.rst

Is there a way to see agreggated data in Dashboard? For example the last 30 days sales grouped by day. I didn’t found it. That info it’s only avalible for me in BaBI, and it doesn’t works with Dashboard.
Thanks.

We have a sales per category (and other reports) related to sale that can probably added to the dashboard.

This can be used as reference for developing customization reports.

And I’ve just remembered there is the Usage of Dashboard module thread that might help too.
