PySide6（QTChart）如何放大X轴并动态更改Y轴范围

Question

我正试图让我的烛台图表能够滚动进出，这将影响x轴上的日期和y轴上的范围。例如，如果我缩小，则日期应该变宽，范围也随之变宽，同时使所有烛台保持一定程度的集中，并且当我放大y轴范围时，范围应该变紧，从而使烛台集中得更近，而x轴日期之间的距离更小，目前，这是一个最小的工作产品，我有图表工作现在：

我尝试模拟大量数据，以便您可以看到我的问题，所有蜡烛都非常小，因为范围没有正确居中，我在x轴上有一个橡胶垫设置，用于选择特定的x轴值，我只是希望能够动态改变y轴，以匹配当前的最小/最大x轴值，也能够放大和缩小滚轮

以下是它当前的样子：
