### 🚑 Any additional [like screenshots]

* **G2Plot Version**: 2.3.35
* **Platform**: mac os

Open the linked CodeSandbox minimal reproduction first and inspect its heatmap data and axis configuration. Trace how the value 15 is mapped to the horizontal coordinate in the chart implementation. Done means the value renders at its intended coordinate and the other heatmap cells remain correctly positioned.
