Hi, I’m currently struggling building custom widgets.  
There is some nice gauge widgets I found in the community.

when I try to mach what I’ see in the code with the documentation I found that most of the configuration properties are not documented.

so… how do other find these attribute and how to use them?

Thanks Ernst

See here for some advice on basic widgets:

> Honestly, in my experience you could do everything with rows because you can override the default flex settings (for that matter you could do nearly everything with just f7-blocks too). But I think that using the alternating rows and cols if you’re actually building a grid of component is just slightly cleaner and easier code to read. I do all my widget development in the MainUI editor. Nothing else that I’m aware of at the moment is going to give you the autocomplete ([ctrl] + [space]) fea…

However, the gauges you are referring to are charts and the chart system utilizes apache eCharts so the documentation for the complete list of those configurations is found on the eCharts pages.
