gnuplot：如何旋转标题

我使用以下命令旋转绘图：

set xtic rotate
set y2tic rotate 
plot ... rotate

---

但是，标题在右侧保持垂直。如何将其旋转到顶部？

如果我正确理解了问题，可以使用

set y2label

而不是

set title

set margins 8,8,4,4
set link x2

unset xtics
set xrange [-3:11]
set yrange [*:*] reverse
set yzeroaxis
set ytics rotate by -90
set x2tics -2,2,10
set x2tics rotate by -90  offset 0,1
unset key

set ylabel "I'm really the y label" offset 1,0 rotate by -90
set y2label "This is y2label turned sideways" offset 1,0 rotate by -90
set y2label font ",20"


plot [u=-10:10] '+' using (10.*sinc($1)):($1) with lines

如果我正确理解了这个问题，也许可以使用

设置标签

而不是

设置标题

set margins 8,8,4,4
set link x2

unset xtics
set xrange [-3:11]
set yrange [*:*] reverse
set yzeroaxis
set ytics rotate by -90
set x2tics -2,2,10
set x2tics rotate by -90  offset 0,1
unset key

set ylabel "I'm really the y label" offset 1,0 rotate by -90
set y2label "This is y2label turned sideways" offset 1,0 rotate by -90
set y2label font ",20"


plot [u=-10:10] '+' using (10.*sinc($1)):($1) with lines

哦，有轴抽签和标签。哦，有轴抽签和标签。
