obsidian-tracker VS obsidian_dataview_example_vault

Hey there... not sure if this is the best spot to ask, but... I'm interested in developing a plugin / webapp inspired by Obsidian-Tracker: (https://github.com/pyrochlore/obsidian-tracker/tree/master)

But you could have a look at the progress bar plugin as well as the tracker plugin.

nothing works and I don't know where to look. Also in the example vault no queries with this structure are available.

This is a very helpful Dataview Vault that someone made available to install. It has many working Dataview examples you can past into your own notes.

Here's a bunch of examples of how to use it - in addition to the documentation linked above.

This is a very helpful training vault full of use case examples you can copy into your own notes (link)

Here it is: https://github.com/s-blu/obsidian_dataview_example_vault

Many working examples with documentation exist in this downloadable Dataview vault (link). Simply install the vault and explore it's list of examples.

I learned more from this post that I read a couple weeks ago than I’ve learned from a year of Googling or reading plug-in instructions. This person deserves a big thank you from me and my much easier life: https://github.com/s-blu/obsidian_dataview_example_vault

I'm certain you can do this without dataviewjs. I'm still learning the ins and outs myself, but I would look at the Dataview Examples Vault for similar queries.
