pgfplots - 缺少一个条形图

我想制作一个有九个条形图的图表。如您所见，它们在代码中为 (0-8)。不幸的是，它只能制作八个条形图。

答案1

ybar interval=0.8如果我将其更改为 justybar并删除，这对我来说是有效的enlargelimits=0.02。我想你可能需要从工作图开始，更仔细地调整设置，并朝着你想要的方向前进。

答案2

如果要使用该ybar interval样式，则需要为每个图提供一个额外的“虚拟数据点”。这是必要的，因为间隔样式用于绘制范围内的条形图，而不是点，因此为了计算最后一个范围的宽度，您需要提供一个上限。

ybar 区间图

或者，您也可以直接使用ybar样式。在这种情况下，您应该使用enlarge y limits=0.02而不是 ，enlargelimits=0.02以确保没有条形图被从侧面切断。请特别注意结果图中刻度线和垂直分割线之间的差异。
