xticklabels 未对齐

Question

请考虑以下 MWE。相同的代码位于另一个具有较大前言的文档中，因此我遇到的未对齐问题可能xticklabels是由于冲突造成的packages。

第一个屏幕截图显示了 MWE 的结果，第二个屏幕截图显示了使用更大的前导码进行编译时的结果。

笔记：对于 MWE，我没有包括特殊格式（例如颜色、破折号等）。

编辑顺便说一句：如果你看一下数据，dataLevelerConverter2.dat你会看到有一个 Kalenderwoche 42。但是，在第一个屏幕截图中，似乎是xticks从 Kalenderwoche 43 开始的。

Answer 1

在这个具体示例中，Luigi 建议Kalenderwochen直接使用 x 坐标，这是一个好主意。但是，如果Kalenderwochen确实包含标签（数字或其他），则它将不起作用：在 John 的文本标签示例中，xtick={0,...,9}必须明确设置。通常，只需使用，但这仅在第一个图中xtick=data没有 s 时才有效。nan

因此，在极少数情况下，您需要从表中提供标签，但无法使用来xtick=data确保刻度和刻度标签同步，这里有一种xtick from table类似于的样式xticklabels from data：

---

这种方法的缺点是，您总是使用所有刻度和刻度标签，而不是让 PGFPlots 确定适当的刻度数。要解决这个问题，您可以设置

    xticklabel={%
        \pgfmathtruncatemacro\datarow{round(\tick)}%
        \pgfplotstablegetelem{\datarow}{Kalenderwochen}\of{dataLevelerConverter2.dat}%
        \pgfplotsretval%
    }

这将从数据表中获取每个刻度位置的适当刻度标签。

Answer 2

@Luigi 和 @Jake 是对的。

xticklabels 是数字

我想使用Kalenderwochen中的dataLevelerConverter2.dat列xticklabels。由于此列包含数字，因此我可以写

\addplot table [x=Kalenderwochen, y=Nachfrage]

代替

\addplot table [x=Wert, y=Nachfrage]

并删除

xticklabels from table = {dataLevelerConverter2.dat}{Kalenderwochen}

xticklabels 不是数字

如果列Kalenderwochen包含除数字以外的其他信息（例如“第一个数据集”，“第二个数据集”），则必须写入

\addplot table [x=Wert, y=Nachfrage]
xticklabels from table = {dataLevelerConverter2.dat}{Kalenderwochen}
