Chart.js	ChartBuddy
type: 'bar'	chartType: 'clusteredBar' (or stacked variants)
type: 'line'	chartType: 'line'
data.labels + datasets[].data	seriesData 2D array (+ isDataTransposed: true)
options.indexAxis: 'y'	orientation: 'horizontal'
options.plugins.legend	legend: { visible, colors }
options.plugins.title	title: { visible, text }
new Chart(ctx, config)	new Insight(el, { chartData })

Example mapping

Chart.js:

new Chart(ctx, {
  type: 'bar',
  data: {
    labels: ['Q1', 'Q2'],
    datasets: [{ label: 'Revenue', data: [100, 112] }],
  },
  options: { indexAxis: 'y' },
});

ChartBuddy:

new Insight('#chart', {
  persist: false,
  chartData: {
    chartType: 'clusteredBar',
    orientation: 'horizontal',
    isDataTransposed: true,
    seriesData: [
      ['', 'Q1', 'Q2'],
      ['Revenue', 100, 112],
    ],
    title: { visible: true, text: 'Revenue' },
    subtitle: { visible: false, text: '' },
    legend: { visible: false },
  },
});
