<p align="center"><img src="https://code.corpglory.net/chartwerk/grafana-chartwerk-panel/raw/branch/main/src/assets/logo.svg" width="150" height="150" /></div>

**Grafana Chartwerk Panel** renders metrics using Chartwerk libraries. For now, it can render as Gauge. We are working on adding new visualizations.

## Features

- Gauge: dynamic thresholds and min / max
- Gauge: conditional icons displaying
- Gauge: reversed direction

## How to use

1. Create a new panel and select Chartwerk as the visualization
2. Add queries with unique aliases
3. Go to the Options Tab and setup panel:
