 **Grafana Chartwerk Panel** renders metrics using ChartWerk libraries. For now, it can render as a line and a series of bars. We are working on adding new visualizations.

## Features

- 2 types of visualizations:
  - line-chart
  - bar-chart
- ability to make panel's time range independent of dashboard's (doesn't work in Grafana 7).
- ability to display template variables inside the panel.
- "Charge" mode: green color for positive graph's slope, red color for negative graph's slope.
- confidence interval (for line).
- customizable X-axis labels.
- customizable grid interval.
