});类型特定选项
| 选项 | 描述 |
|---|---|
diverging | 发散色标（负蓝色，正红色）。 |
showLabels | 显示行/列标签。 |
dendrogramRowWidth / dendrogramColHeight | 树状图大小。 |
rowDendrogram / colDendrogram | 层级树对象。 |
变体
发散色阶
设置 diverging: true 得到以零为中心的蓝-白-红色阶。
KatuCharts.chart('container', {
series: [{
type: 'clusteredheatmap', diverging: true,
data: [{ x: 0, y: 0, value: -2.4 }]
}]
});Common errors
- Why does my 聚类热力图 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.

- Install with `npm install katucharts.js`, import the module with `import 'katucharts.js/bio';`, then call KatuCharts.chart(container, { chart: { type: 'clusteredheatmap' }, series: [...] }).
