* **G2Plot Version**: 2.4.16
* **Platform**:

Start with the linked CodeSandbox reproduction at index.ts and reproduce the dual-axis chart's box-selection interaction using G2Plot 2.4.16. Investigate the behavior before and after resetting the selection; done means every data line remains on or above the X axis.
