| Charts | 2019-03-06 | Guide to Chart.js usage in Congo | Congo includes Chart.js for powerful charts and data visualisations. |
|
Congo includes support for Chart.js using the chart shortcode. Simply wrap the chart markup within the shortcode. Congo automatically themes charts to match the configured colorScheme parameter, however the colours can be customised using normal Chart.js syntax.
Refer to the [chart shortcode]({{< ref "docs/shortcodes#chart" >}}) docs for more details.
The examples below are a small selection taken from the official Chart.js docs. You can also view the page source on GitHub to see the markup.
