Common errors
- Why does my circos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.
FAQ
- How do I create a circos图 chart in JavaScript?
- Install with `npm install katucharts.js`, import the module with `import 'katucharts.js/bio';`, then call KatuCharts.chart(container, { chart: { type: 'circos' }, series: [...] }).
- What are the circos chart types called?
- circos, circosHeatmap, circosComparative and circosSpiral. Note the camelCase. There is no circosChord type — it was documented in error in earlier versions and has never existed.
