chartist-plugin-legend

Implements a legend for Chartist charts.

Demo

Install

$ npm install chartist-plugin-legend --save

As styles are very different with each project, no CSS is included. You can copy paste this to use as base:

.ct-legend {
    position: relative;
    z-index: 10;

    li {
        position: relative;
        padding-left: 23px;
        margin-bottom: 3px;
    }

    li:before {
        width: 12px;
        height: 12px;
        position: absolute;
        left: 0;
        content: '';
        border: 3px solid transparent;
        border-radius: 2px;
    }

    li.inactive:before {
        background: transparent;
    }

    &.ct-legend-inside {
        position: absolute;
        top: 0;
        right: 0;
    }

    @for $i from 0 to length($ct-series-colors) {
        .ct-series-#{$i}:before {
            background-color: nth($ct-series-colors, $i + 1);
            border-color: nth($ct-series-colors, $i + 1);
        }
    }
}

Usage

require('chartist-plugin-legend');

new Chartist.Bar('.ct-chart', data, {
        stackBars: true,
        plugins: [
            Chartist.plugins.legend()
        ]
    },
});
