我尝试为我的心电图创建一个自定义网格，但没有任何效果。
我想得到一个具有特定突出显示线的网格。为了减少我使用的网格线xyMultipleSeriesRenderer.setXLabels(10)和xyMultipleSeriesRenderer.setYLabels(10).
现在我想从 X 轴和 Y 轴每隔四行突出显示，或者使它们比其他行大。
这是我发现的东西。
这几乎是我正在寻找的。但我还需要 y 轴的阈值。
有人有想法吗？我很高兴任何提示！
补充：
是的，突出线条真的很容易。我只是在 (0,20) 处添加一个点，在 (1000,20) 处添加一个点。这对水平线非常有效。
但是如果我想对垂直线做同样的事情，我会得到一条对角线。对于静态折线图，如果我只在 (30,0) 处添加一个点，在 (30,100) 处添加一个点，它就可以工作。但是，如果我对实时折线图做同样的事情，我只会得到这种丑陋的倾斜。谁能给我解释一下？？？我还尝试更改（30,0）和（29,1000）之类的值，但我仍然得到对角线:(
解决方案是添加一些额外的系列，每个系列只包含 2 个点，每个这样的系列都会定义这样一条线。
你好谢谢你的回答。但是我已经有两个系列了。我有一个系列可以生成我的动态图。我试着向你展示我的代码。

所以我没有理由，为什么垂直线不垂直。你有想法吗？
