C# 滚动不适用于ZedGraph

我在ZedGraph中有一个折线图。 数据每秒都来自串行端口。 图表正在运行。 但不要在X轴上滚动（滚动），并在左角被压缩。 我需要图表从右向左滚动，日期和时间显示在X轴上

对于自动滚动，当新数据输入时（或计时器超时），您必须手动滚动：

谢谢，这对我有帮助。然而，我需要的图形是从右向左移动，就像在这个视频中一样。你必须将添加的代码放入“timer1_Tick”函数中，而不是构造函数中。因为每次，当新数据进来时，你必须更新最小值和最大值1。5分钟后轻松停止计时器。2.您必须创建一个csv文件，检查日期并将其填入csv文件的列中。导致跳转的原因是，zedgraph每次都会自动重置basetic。不久前我也遇到过同样的问题，但我不知道解决办法了。。。我认为这与此有关，我必须更改zedgraph的源代码以实现此行为。查看源代码通常是一个好主意，这样您就可以更好地理解zedgraph在做什么。关于您的excel问题：评论不是提出全新问题的地方。提出一个新问题，更多的人会注意到它。
