qt6.6.2 上跑,报错找不到属性

[StoneBang]

[MrHulu]

@StoneBang 我没有在Qt6上尝试过，我感觉是x和y与基础属性冲突了，Qt6的检查可能比较严重，你可以使用以下补丁尝试？

按照你的思路,修改完了是可以正常运行了 可是切换tab的时候,报错了.内容如下:

[MrHulu]

@StoneBang 你的环境是什么？我可能需要下载一个Qt6测试一下，这个问题应该不存在的，十分奇怪

[StoneBang]

是我个人问题,修改的时候,yAxis没有被赋值.现在已经跑起来.只是现在效果交互并不是特别多.但是作为自定义qCsutomPlot并且引入到qml中使用,是个对新手很好的启蒙项目.感谢开源

熟悉了可以直接改源码以满足你的交互效果，应该很简单。

我准备关了这个issues了，你是否还有其他问题？
