能支持水平条形图吗？也就是说，柱子是水平方向的bar chart.

Is it possible to scroll the chart horizontally ?
Sometimes data could be longer , what to do in that case

测试方法, 长按柱状图显示数据之后,在动画结束之前立即切换界面,此时将会报错

我尝试试了一下 为什么最多只能设置7个数据

I'm currently attempting to modify the source code of your repository to implement chart zooming and dragging through gestures like onScaleStart/onScaleUpdate/onScaleEnd, but I'm encountering some issues with zooming. Could you please add zooming functionality to your codebase, or provide some suggestions on my code? (I can offer some compensation if successful.)

您好!请教一下,为什么x轴我设置了十几条数据还是一直显示7条。恕在下愚钝没找到这个api,望先生不吝赐教。
