### Version 4.8.0 ### Reproduction link [https://echarts.apache.org/examples/zh/editor.html?c=bar-background](https://echarts.apache.org/examples/zh/editor.html?c=bar-background) ### Steps to reproduce showBackground为空或为false的情况下，修改为true再setOption，会导致图表crash。 可在示例中先将showBackground修改为false，再修改为true，控制台报错。 ``` TypeError: Cannot read property 'useStyle' of undefined at kf._update (echarts.min.js?_v_=1595472244966:22) at kf.execute (echarts.min.js?_v_=1595472244966:22) at e._renderNormal (echarts.min.js?_v_=1595472244966:22) at e.render (echarts.min.js?_v_=1595472244966:22) at jh.progress (echarts.min.js?_v_=1595472244966:22) at ac (echarts.min.js?_v_=1595472244966:22) at jh.qh.perform (echarts.min.js?_v_=1595472244966:22) at echarts.min.js?_v_=1595472244966:22 at e.<anonymous> (echarts.min.js?_v_=1595472244966:22) at Array.forEach (<anonymous>) ``` ``` TypeError: Cannot read property 'useStyle' of undefined at DataDiffer._update (BarView.js:201) at DataDiffer.execute (DataDiffer.js:112) at ExtendedClass._renderNormal (BarView.js:251) at ExtendedClass.render (BarView.js:109) at Task.progress (Chart.js:281) at doProgress (task.js:217) at Task.push../node_modules/echarts/lib/stream/task.js.taskProto.perform (task.js:157) at echarts.js:1474 ``` ### What is expected? 正常显示柱子背景 ### What is actually happening? 图表报错。 <!-- This issue is generated by echarts-issue-helper.
