Basic Implementation

To render a grouped bar chart, you first have to set up a container in your HTML.

<div id="barChartGrouped"></div>

Next in your script file, you need to import the meistercharts package and create a new instance of a bar chart.

const meistercharts = require('@meistercharts/meistercharts/meistercharts-easy-api')

const chart = meistercharts.createBarChartGroupedFromId('barChartGrouped')

This will render an empty chart with the default styles.

Add data to the chart

To add data to the chart, you need to call the setData- function on the chart instance with your data.

chart.setData({
  categories: [
    { label: 'Monday', values: [2, 20, 30, 40] },
    { label: 'Tuesday', values: [30, 32, 15, 50] },
    { label: 'Wednesday', values: [20, 25, 35, 50] },
    { label: 'Thursday', values: [20, 25, 35, 50] },
    { label: 'Friday', values: [20, 25, 12, 40] }
  ]
})

The setData- function will accept an object of the type BarChartGroupedData.

Customize the chart style

You can customize how the chart looks by calling the setStyle- function on the chart instance.

chart.setStyle({
  barGap: 5,
  barSize: 20
  // ...
})

The setStyle function accepts an object of the type BarChartGroupedStyle.
