1.在一个大的canvas里绘制一个小型的geoMap，设置了roam后只有Map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示例是可以被拖动和缩放的呢？
谢谢！

发现了同样的问题。不过可以通过需要放到区域和整个Map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：
_api.getModel()?.getSeriesByIndex(0).coordinateSystem
_rect
// _chinaMapRect 为整个Map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
