andbjer opened a new issue #15877: URL: https://github.com/apache/echarts/issues/15877
### Version 5.2.1 ### Reproduction link [https://codesandbox.io/s/echarts-visualmap-bug-thlco](https://codesandbox.io/s/echarts-visualmap-bug-thlco) ### Steps to reproduce We use VisualMap in our project to mark the area red when the values are below zero for example. After upgrading to v5.2.1, VisualMap sometimes doesn't draw anything and just displays an empty plot. You can refresh the reproduction to see that it works sometimes and other times not. This seems to be an issue introduced in v5.2.1 as I can't reproduce it when downgrading to v5.2.0. ### What is expected? That the VisualMap specified is always applied and that the plot is drawn into the plot area. ### What is actually happening? VisualMap is not always working and plot is sometimes not drawn at all when providing VisualMap. <!-- This issue is generated by echarts-issue-helper. DO NOT REMOVE --> <!-- This issue is in English.
