filip-707 opened a new issue, #21408: URL: https://github.com/apache/echarts/issues/21408
### Version 5.x, 6.0.0 ### Link to Minimal Reproduction https://jsfiddle.net/us36p2Lk/1/ ### Steps to Reproduce see [https://jsfiddle.net/us36p2Lk/1/](https://jsfiddle.net/us36p2Lk/1/) (or attacheded bug-report.html file) see empty chart. all y-axis are ok notice y-axis on the right 'axis_300', it is the second y-axis on the right its min and max are set to 300, which is fine at bottom of chart, there is a listbox, you can choose a signal to be added (it add 1 or more series to chart) when a serie is added, the 'axis_300' min/max becomes -100/100 it happens to be left y-axis (axis_100) min/max if you add signal C which is linked to 'axis_300', data is displayed accordinging to y-axis wrong value. when zoom is applied (using mouse scroll, or programmatically), y-axis 'axis_300' min/max are restored to 300. the code which add series to chart, does not modify option.y-axis. i expect y-axis 'axis_300' to remaing to min/max 300. Why does it take y-axis[0] min/max temporarily is a mystery. ### Current Behavior when a serie is added, the 'axis_300' min/max becomes -100/100, but min/max are set to -300/300 respectively when zoom is applied (using mouse scroll, or programmatically), y-axis 'axis_300' min/max are restored to 300. ### Expected Behavior the code which add series to chart, does not modify option.y-axis. i expect y-axis 'axis_300' to remaing to min/max 300. ### Environment ```markdown - OS: windows 11 - Browser: Edge 142.0.3595.94 & Chrome 142.0.7444.176 - Framework: pure html + css Html + css generated to simplify debugging, problem observed in a more complex environment. ``` ### Any additional comments? I can see that it happens only to right y-axis 'axis_300' which min/max are greater than left y-axis min/max (-100/100). Also, when zoom is applied, echart corrects the problem automatically, which means the underlying min/max is set correctly. -- This is an automated message from the Apache Git Service.
