Question

我有一个列系列图表工作正常。

我有一个我需要添加的功能，我想要将horizontall滚动启用到x轴的绘图区域。

以下是截图：

enter image description here

如果您看到屏幕截图我有六个项目，并且由于项目数量较多，条形图非常薄，所以假设我有20个项目，那么条形图将根本不可见。

那么我们可以让X轴条水平滚动吗？

Answer 1

最后我已经解决了，但我没有对API进行任何更改，而是采用了以下方法。

1）我们可以选择滚动整个图表。

2）使整个条形图滚动，然后删除Y axis值。

3）现在使用Y axis values创建一个使用Grid row definitions的虚拟布局。这将是您的根Grid。

4）现在在根网格中，您可以绘制网格图。

5）现在当您进行n次测试时，您可以滚动图表，但您的Y axis值的虚拟布局保持不变，因此对于用户来说，它看起来像是条形图滚动。
