I appreciate the videos, but would be nice if some of them would dive deeper. I struggle to this day to use nested Variables and I'm pretty and how to reference Query elements in the dashboard views, like tables and graphs, for example.

Suggestion: increase the detail of the explanations, dive deeper, stay calmer, reduce the entertainment clutter: waving of hands, the disturbing 80's gaming sounds and the background music.

i'm trying to use the password element in the business forms to create a login function for the user that will return data that is filtered for that user. can i use variables to store the username as a variable and then use the variable in a query? how will i store, and reference a variable in a query though?

Regarding non labeled fields- when choosing adhoc filter as a variable for the dashboard, i don't see them in the list. Only labeled one. Is there a way to have adhoc filters to all fields?

There's an issue in one of the example. It should be ${names} not ${name]

Hello, I'm interested in creating custom variables for my project. Specifically, I'd like to incorporate a date picker as a variable. I'm planning to develop a panel plugin with this feature. Is there a method to integrate it into the type dropdown within the variable section and display the date picker

I am using the infinity plugin to hit a URL, that returns a JSON. I would like to extract one of the fields in JSON, and insert it into another URL on a click event. Click event will display a detail table of the parent record.

how to use the ad-hoc filters in a query please tell me
I'm looking for it for quite a while now but can't find it

Should I move to code mode for variable mapping for a DB sourced dashboard ? What I need is simply showing date range filter I use in query builder to end users. When I choose between option I can select a date range, but I would like to leave it to dashboard end user (in public view mode). I can do it by coding, but I'm curious if there's any way to map variables to query builder params.

These videos go into exactly as much depth as to not be useful at all.

After the intro I thought, maybe I'll have a good idea how to make easily parameterizable template dashboards for different OSes/exporters, but after watching to the end, I still don't know if that's even possible… :/

Does anybody in the US use this software?

[erlandodk]

Stop the zoom-cuts! It's almost giving me a seizure. It's unbelievably distracting!

This is the first functionality I've attempted. Not only is this video useless and too brief but the UI/UX of your tool is horrid. It's been downhill since this video.
