我想将最小值和最大值添加到下图中。到目前为止,我在网上找不到解决方案。
如果可能的话,我想以特定的格式写入我的数据。
谢谢您的帮助,我不太熟悉在 Latex 中进行绘图。
Desired format for "Data1" as an example:
avg min max
2.0 1.5 3.0
2.0 1.5 3.0
2.0 1.5 3.0
2.0 1.5 3.0

欢迎!这添加了误差线。我不确定您想如何提供误差,所以暂时我只是从您的表格中添加了六列,以指示误差线的尺寸(+ 和 -)。

多谢薛定谔的猫!
我无法及时向您提供错误格式。我稍微修改了您的代码以适应我想要的错误格式。这种错误格式更容易从我的数据集生成。我在您的代码中添加了绘制行 N 到 M 的图表,解释如下这里。
再次感谢!
