如何在三元图的 z 轴上插入箭头来指示该轴上元素的递增顺序？

我需要帮助，如何在三元图中的z 轴上插入X_{Bi}和。表示下标，而 则与 LaTeX 中的一样，表示z 轴上的 是从左到右增加的。在下面显示的示例中，我想使用放置在 前面或顶部的 来显示在每个图中从 0 增加到 1.0。 rightarrowsubfiguresX_{Bi}XBirightarrowBirightarrowX_{Bi}X_{Bi}

答案1

能够通过在代码中的\node at (zticklabel cs:0.5) [anchor=north] {$X_{Bi}$}行前插入和在代码中（正如 Jake 今天所建议的那样）成功地将 X_{Bi} 沿 z 轴定位后，我观察到通过在该行的最后一项中添加该项目，得到了回答该问题的预期结果。因此，我现在得到以下结果：\end{ternaryaxis}activate clip=false$\rightarrow$\node
