我想在用户放大我的图表时调整列宽。你能建议任何方法或选项吗?我搜索了 documentation但我没有找到任何解决方案。到目前为止,我尝试通过更改条形宽度百分比、响应选项和笔划宽度来尝试。笔划有重叠条的副作用,但我需要它们分开

缩放前

Before Zoom

Zoom 之后的实际行为

最佳答案

这不是一个完整的答案,但想分享我的发现。
IMO OP 请求的功能应该是默认行为。

无论如何,我发现通过使用zoomed事件,我们可以找到缩放的x轴范围。
然后从该范围之外的系列中删除数据点并重新绘制图表。
这会导致完全符合预期的行为。
但是,这会破坏缩小到原始系列的能力。

要完成这项工作,我认为您需要实现自定义缩放按钮,
允许跟踪发生的操作、放大或缩小。
这将使您知道重新绘制图表时要包括哪些数据点。
您可以使用 zoomX 方法手动设置缩放级别。

请参阅以下工作代码段了解仅放大功能。
