How do I create a cascada chart in JavaScript?

Install with `npm install katucharts.js`, then call KatuCharts.chart(container, { chart: { type: 'waterfall' }, series: [...] }).

Why does my cascada chart render as a line chart?

The chart type was not registered. KatuCharts logs "KatuCharts: unknown series type " ", falling back to line" and draws a line chart rather than throwing. Import the module the type belongs to — for example `import 'katucharts.js/bio';` — before creating the chart.

Why do I get "Cannot read properties of null (reading 'appendChild')"?

The container element does not exist when the chart is created. Create the chart after the element is in the DOM: in React that means inside useEffect, not during render.

Why is the chart rendering with zero height?

The container has no height. A div with no content collapses to zero. Give it a height in CSS, or pass `chart: { height: 400 }` in the options.

KatuCharts.chart('container', {
  chart: { type: 'waterfall' },
  xAxis: { categories: ['Start', 'Producto', 'Opex', 'Total'] },

Variaciones

Subtotales y totales

Usa puntos isIntermediateSum e isSum para subtotales y un total final.

KatuCharts.chart('container', {
  chart: { type: 'waterfall' },
  series: [{
    dataLabels: { enabled: true, format: '{point.y}' },
    data: [
      { y: 120 },
      { y: 56 },
      { y: 38 },
      { isIntermediateSum: true },
      { y: -64 },
      { y: -18 },
      { isSum: true }
    ]
  }]
});

Common errors

Why does my cascada chart render as a line chart?: The chart type was not registered. KatuCharts logs "KatuCharts: unknown series type "<type>", falling back to line" and draws a line chart rather than throwing. Import the module the type belongs to — for example `import 'katucharts.js/bio';` — before creating the chart.
Why do I get "Cannot read properties of null (reading 'appendChild')"?: The container element does not exist when the chart is created. Create the chart after the element is in the DOM: in React that means inside useEffect, not during render.
Why is the chart rendering with zero height?: The container has no height. A div with no content collapses to zero. Give it a height in CSS, or pass `chart: { height: 400 }` in the options.
