+ Whether to apply transition animation when resize, including `duration` and `easing`, the default `duration` is 0, that is, no transition animation is applied.

**Tip:** Sometimes charts may be placed in multiple tabs. Those in hidden labels may fail to initialize due to the ignorance of container width and height. So `resize` should be called manually to get the correct width and height when switching to the corresponding tabs, or specify width/heigth in `opts` explicitly.

**Tip:** 有时候图表会放在多个标签页里，那些初始隐藏的标签在初始化图表的时候因为获取不到容器的实际高宽，可能会绘制失败，因此在切换到该标签页时需要手动调用 `resize` 方法获取正确的高宽并且刷新画布，或者在 `opts` 中显示指定图表高宽。
