Request for a longer tutorial

I am fairly new to Grafana. I know how to make dashboards and add panels, but the README leaves out a lot of setup details for this plugin. Here is a list of questions I have.

• I only have InfluxDB installed. Do I need to install MySQL like you showed in your pictures
• What information does the MySQL database need to contain for this plugin to work?
• You showed yourself setting the "button_text" and "time_from" in your database queries. Do I need to have that information also in the database? Or do you just make a query to an empty database and provide all the information in the grafana query?
