Few PRs on pie chart plugin

Hello,

While I’m doing my backend business using Apache Flink as shown in https://berlin.flink-forward.org/kb_sessions/predictive-maintenance-with-apache-flink, I’ve been also implementing interactive dashboards for my customer using Grafana mainly with the official pie chart plugin. A dashboard looks below:


Besides pie chart plugin, I also modify worldmap plugin to show my customer which sensors generate alarms.

Using pie chart plugin, I found some ideas to improve it. So I recently created three PRs for pie chart plugin:

I really hope the PRs to be merged :slight_smile:

Thanks!

p.s. please let me know if I forget to take steps to conduct before creating PRs
