无法在 "label" 和 "key" 之间设置不同的字体大小
Unable to have different font size between "label" and "key"
我有两个问题。
1) 我正在尝试为 label 和 key 使用不同的字体大小。奇怪的是，下面的 MWE 无法这样做，尽管从那里的手册来看语法似乎是正确的。
有没有明显的错误？
2) 如何让 Z 轴在最右边的 z 列中也用其 ztics 标记。我没有成功使用 z2tics 完成它。

关于第 2 点：gnuplot 没有 z2 轴（它在 3D 中也没有 x2 和 y2 轴），你不能 select zaxis 的位置。
