htr3n opened a new issue #15579: URL: https://github.com/apache/echarts/issues/15579
### Version 5.1.2 ### Reproduction link [https://codepen.io/htr3n/pen/YzQKMrq](https://codepen.io/htr3n/pen/YzQKMrq) ### Steps to reproduce 1. Define a chart with the following options - A-axis with type "category", set `data` to some kind of category such as `["6:00", "6:30", "7:00", "7:30"]` - Y-axis with type "category", set `data` to some sort of category for instance `["A", "B", "C", "D"]` - A series with a list of null input data: `data: [null, null, null, null],` ### What is expected? The chart should not render any values because they are all null. ### What is actually happening? The chart renders the first value at the position of the first Y-axis category. --- Replace `null` with `undefined`, the chart seems to render correctly. <!-- This issue is generated by echarts-issue-helper.
