大家好，我想删除此图中的黑线，该怎么做？

答案1

为此，您只需添加draw=none到情节选项即可。

我对你的情节做了一些其他改进：

extra x ticks您可以使用和，而不必使用另外两个轴来使刻度标签显示在所有侧面extra y ticks。您可以ticklabel通过设置来独立于正常刻度来设置这些额外刻度的选项extra x tick style={<options>}。

除了使用\addplot绘制垂直线之外，您还可以使用

after end axis/.append code={
    \draw ({rel axis cs:0,0}-|{axis cs:0,0}) -- ({rel axis cs:0,1}-|{axis cs:0,0});
}

这将确保线始终跨越图的整个高度，而不管轴限制如何。

您可以xticklabels使用 来更改颜色条的，方式类似于更改额外的 x 刻度的colorbar style={xticklabels={...}}。
