android中带有自定义y轴空间问题的折线图

我正在使用Achartengine1.1.0.jar开发折线图

当我画出最后的折线图时，我面临一个问题

绘制的y轴标签在标签和一起绘制的所有标签之间没有垂直间距

我附上了我画的折线图的屏幕截图

在这里，我还附加了代码片段

创建时受保护的void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.activity_main）；
对于（inti=0；i只需替换您的行即可
setYLabels先生（49）

到

mrender.setYLabels（10）

减小SetyLabel的大小时，将增加Y标签之间的间距
