堆叠条形
水平堆叠条形——相同的堆叠 API，交换了坐标轴。
KatuCharts.chart('container', {
chart: { type: 'bar' },
xAxis: { categories: ['Onboarding', '支持', 'Pricing', 'Docs'] },
plotOptions: { bar: { stacking: 'normal' } },
series: [
{ name: 'Agree', data: [62, 71, 44, 80] },
{ name: '中立', data: [22, 18, 31, 12] },
{ name: 'Disagree', data: [16, 11, 25, 8] }
]
});Common errors
- Why does my 条形图 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.
