在下图中，我需要有透明的标记，但不能有线穿过它们。例如，三角形是透明的，但里面有一条线，而圆圈是白色的，但不透明，所以当它们与其他标记重叠时，我看不到后面的标记（例如，第四个红色圆圈覆盖了它后面的蓝色 +）。我该怎么做？我试过和fill，opacity但似乎都没有用。

答案1
我想，要实现这一点，你需要让情节标记节点，使得 Ti钾Z 可以\pgfpointshapeborder在内部使用（参见 pgfmanual 第 1031 页）在边界处停止绘图。据我所知，这对于普通的绘图标记是不可能的。因此，这个答案提供了一种新样式，spare node marks您可以将绘图标记形状传递给它。它（滥用）用于show path construction绘制线段。在目前的形式下，它仅限于直线，但也可以让它适用于曲线。在你的代码中，我替换了
\addplot [color=red, mark=triangle, mark options={solid, red,fill=white, fill opacity=0}]
经过
\addplot [color=red,spare node marks={regular polygon,regular polygon sides=3,inner sep=2pt}]
结果是
如您所见，三角形内的蓝线没有消失，红色情节线也没有穿过情节标记。答案也有一种spare marks风格（我的第一次尝试），但由于缺乏合适的\pgfpointshapeborder坐标而受到影响。
