发现了同样的问题。不过可以通过需要放到区域和整个地图的坐标宽高比例来设置 zoom 属性进行放大。
_api.getModel()?.getSeriesByIndex(0).coordinateSystem
这个 API 属性中可以拿到 _rect
属性信息:
// _chinaMapRect 为整个地图的 rect 信息
// regionInfo._rect 是某个省份的,可以在 coordinateSystem.regions 获得
const widthPer = _chinaMapRect.width / regionInfo._rect.width
const heightPer = _chinaMapRect.height / regionInfo._rect.height
echarts.setOptions({
series: [{
center: regionInfo.center,
layoutCenter: ['50%', '50%'],
layoutSize: '100%',
zoom: Math.min(widthPer, heightPer)
}]
})
这样可以获得理想的交互效果

1.在一个大的canvas里绘制一个小型的geo地图,设置了roam后只有地图周围可以拖动,周围大部分空表区域都不能拖动
2.在实现点击区域放大某一地区的功能(手动设置center和boundingCoords)后,roam的可拖动区域就变成了被选中的地区,超出范围的也不能拖动了。。。
有什么办法可以设置整个echart实例是可以被拖动和缩放的呢?
谢谢!
