我如何增加刻度之间的间距，使第一个刻度更靠近轴，并从 pgfplot 中删除空白？

Question

问题标题说明了一切，我的图看起来不太好看。我想增加每个 xtick 之间的间距，使第一个 xtick 更靠近 y 轴，并删除图右侧没有 x 刻度的那个空间。

如果可能的话，请说明如何设置每个图例的颜色/绘图，因为每个图例列都有很多共同点，所以我想让同一列中的每个图例具有相同的颜色但不同的绘图。我不知道是否有人会理解这一点，但我试过了。

输出如下：

我的代码很长，但它在这里：

Answer 1

要删除左右边缘的空白区域，可以设置enlarge x limits=false。

要影响绘图样式，您可以提供类似于选项的选项red, mark=*，\addplot [...]也可以设置cycle list采用绘图样式列表的选项。
