求助： 双轴折柱混合图表，柱状图不显示。

[Yon Xu]

BizCharts Version: "bizcharts": "^4.1.16",
Platform: React
Mini Showcase(like screenshots):
模仿这个例子做的：https://bizcharts.taobao.com/product/BizCharts4/demo/414

从后端拿到数据后，柱状图不显示，但是如果本地定义同样的数据，却可以显示 (用state的data不显示；用data1却可以)。
请问这是为什么？

const data1 = [
        {city: 'Melbourne (C)', sentiment: 0.40320021514051374, mean_aud: 69.078},
        {city: 'Sydney (C)', sentiment: 0.42084360449192, mean_aud: 77.84},
        {city: 'Adelaide (C)', sentiment: 0.4243085880640466, mean_aud: 74.843},
        {city: 'Perth (C)', sentiment: 0.4495846876128567, mean_aud: 90.6},
        {city: 'Brisbane (C)', sentiment: 0.41321651725074704, mean_aud: 68.058}
    ];
