The chartist library is ~12kb minified, gzipped.

The default css is ~1.4kb minified, gzipped.

Syntax

chartist basically supports three chart types:

<xtal-chart-istic draw line-chart={lineChartDataAndOptions}></xtal-chart-istic>

<xtal-chart-istic draw pie-chart={pieChartDataAndOptions}></xtal-chart-istic>

<xtal-chart-istic draw bar-chart={barChartDataAndOptions}></xtal-chart-istic>

The properties lineChart, pieChart, barChart needs to consist of two properties:

data and options, e.g.:

<xtal-chart-istic draw line-chart='
{
    "data": {
        "labels": ["Mon", "Tue", "Wed", "Thu", "Fri"],
        "series": [
            [5, 2, 4, 2, 0]
        ]
    },
    "options": {
        "width": "600px",
        "height": "300px"
    }
}
'></xtal-chart-istic>

These data and options subproperties are passed to the second and third arguments of chartist api:

this.chart = new Chartist.Pie(
    this._chartTarget,
    this._pieChart.data,
    this._pieChart.options,
    this._pieChart.responsiveOptions,
);

As you can see, there's a third sub property that can be passed in -- responsiveOptions, which are demonstrated frequently in the chartist examples.

"draw" is a boolean attribute / property that allows you to delay or prevent rendering (for example, if element is hidden);
