10.0.0-beta2 ​

2026-05-20

  • 🆕 New Features

    • Support multiple y-axes. Multiple y-axes can be created in the same pane, and indicators can be bound to a specified y-axis through yAxisId.
    • Add instance methods overrideXAxis(options) and overrideYAxis(options) for independently configuring the x-axis and y-axis.
    • The chart now supports automatically listening to container size changes and calling resize().
    • Add the text type to indicator figures, allowing indicator figures to draw text directly.

  • 👉 Changes

    • In the chart method init(ds, options), options.layout has been changed from an array structure to an object structure, with basicParams and panes added:
      • basicParams supports configuring barSpaceLimitMin, barSpaceLimitMax, yAxisPosition, yAxisInside, paneMinHeight, and paneHeight.
      • panes is used to configure pane layout, and pane content supports specifying a y-axis configuration for an indicator through { indicator, yAxis }.
    • The instance method createIndicator(indicator, isStack?, paneOptions?) has been changed to createIndicator(indicator, options?), and options supports isStack, pane, and yAxis.
    • setPaneOptions(options) no longer includes axis configuration. Use overrideXAxis(options) or overrideYAxis(options) for axis configuration.
    • Add yAxisId to the filter parameter of convertToPixel(value, filter?) and convertFromPixel(coordinate, filter?).

  • 🐞 Fixed the parameter type error of the instance API setZoomAnchor.

  • 💄 Optimized the build process. The build tool has been changed from rollup to Vite, and type-check has been added.
