Responsive Resize

@ioto/use-echarts integrates ResizeObserver, so the chart resizes with its container without manual resize() calls.

Demo

Resize the container width to see the chart adapt.

<template>
  <div :style="{ width: containerWidth + 'px', height: '400px' }">
    <ECharts :options="options" />
  </div>
</template>

How it works

const ro = new ResizeObserver(() => {
  instance?.resize();
});
ro.observe(containerRef);
