创建下图
在你开始之前：对于\begin{tikzpicture}...\end{tikzpicture}这个问题中的每一个，我都使用真实的\input{path/picNumber.tex}内容\begin{tikzpicture}...\end{tikzpicture}。对于这个问题，我使用它只是\begin{tikzpicture}...\end{tikzpicture}为了更好地理解。
如您所见，x 轴的标签发生了偏移。为什么？仅当我在 x 轴刻度之间引入自定义单位长度时，才会出现这种情况，例如unit length = 10em per .5 units。我在 x 轴刻度之间使用自定义单位长度来拉伸图形的宽度，因为实际上我有数千个数据点，如果我在 x 轴刻度之间保留标准单位长度，那么我的图形只会变成黑框，因为数据量太大。
如何让移位的标签居中？
提前感谢您的帮助和努力！
答案1
键label={[<options>]<text>}key 将轴的标签设置为<text>。此文本将放置在节点内，并且<options可以使用 > 来配置此节点的呈现方式。您必须说node style来设置节点的样式。
在此示例中，节点向右移动了10em，相当于 0.5 个单位，从 0.25 移动到 0.75。
