2.如何将视点设置为底部并将y轴薄荷限制到底部值？ （例如附加图像底部）我想将视点设置为底部。我尝试了这个代码，但仍然有一些填充。
XAxis xAxis = mBarChart.getXAxis();
xAxis.setAxisMinValue(0);
I want to trim this padding.
我想修剪这个填充。

int maxCapacity = 100;
LimitLine ll = new LimitLine(maxCapacity, "Max Capacity");
chart.getAxisLeft().addLimitLine(ll);
You can also style the line by:
您还可以通过以下方式设置样式：
ll.setLineWidth(4f);
ll.setTextSize(12f);
2) This method may be useful:
2）这种方法可能有用：
chart.setViewPortOffsets(float left, float top, float right, float bottom);
You can read the documentation here.
您可以在此处阅读文档。
3) This method is what you need:
3）这个方法是你需要的：
lineDataSet.setDrawCircles(false);
Once again, its all available in the documentation.
