带有 PGFPlots 的条形图：两个组，每个组有两个类别和两个条形图

使用\pgfplots，我得到了如下所示的条形图： enter image description here

相反，我希望有类似的东西，这样我就有两个组（“Freie Wiedergabe Tag 1”和“Freie Wiedergabe Tag 2”），分为两个类别（“Erinnert”和“Nicht erinnert”），每个类别有两个条形（“neutral”和“negativ”）。我不知道该怎么做：

答案1

数据点可能不在正确的位置，但除此之外，还有一种实现方法如下所示。我将坐标改为数值 x 值 (1,2,3,4)，而不是符号坐标，并设置xticklabels={Erinnert,Nicht erinnert,Erinnert,Nicht erinnert}。因此，每个类别中的四个数据点\addplot应对应于这些类别，前两个代表第一天，后两个代表第二天。

然后我添加了两个extra x ticks={1.5,3.5}（在两组条形图的中间），带有extra x tick labels={Freie Wiedergabe Tag 1,Freie Wiedergabe Tag 2}。对刻度标签进行了一些垂直移动。
