![设置 xstep 和 ystep pgfplots](https://linux22.com/image/268087/%E8%AE%BE%E7%BD%AE%20xstep%20%E5%92%8C%20ystep%20pgfplots.png)
我有这个 MWE。我的问题是如何在轴上设置 xsep 和 ystep,以便它们正确显示,而无需事先知道值的范围:xtick={0,0.1,...,1}
,ytick={80,85,...,120}
。例如,对于x
,我希望只有类似的东西xstep=0.1
。

您仍然可以强行按照评论中给出的想法行事。但您的工作流程非常有趣,尽管我不知道您为什么要这样做。compat=newest
如果将来的版本决定更改您使用的选项,也会破坏您的代码。
在这里,我们将最小值和最大值声明嵌入到自定义样式中,并在样式中临时进行少量计算。这可能有点过头了,但可以将其作为概念证明。我仍然认为手动方法会更容易,但这只是我的观点。
