Improve graphs/dashboard empty states

[paolodamico]

Is your feature request related to a problem?

Currently we have two different empty states for when graphs (in trends and dashboards) have no data. Both of these states are not great (either from a UI or UX standpoint [not very actionable in how to fix]).

Describe the solution you'd like

I'd like us to come up with some very useful and visually attractive empty states. Similar to what we did when a query time outs or errors.

Describe alternatives you've considered

Keep the current messages.

Thank you for your feature request – we love each and every one!

What would you want to see here? Aside from something more visual, probably some text about:

• Common troubleshooting steps
• Instructions on how to track events if total number of events in instance == 0?
• Other ideas?

Pasting this for my own reference of other error states:

• Additional common troubleshooting options: extend the search (i.e. remove filters or extend the timeframe).
• If it's action-based, maybe something around checking the action to make sure it's property set up to match the desired events.
• If it's a property aggregate value there might also be something around properties having incorrect types (e.g. numbers formatted as strings), or events not having the correct property.
