GNUPLOT可以动态准备索引标签吗? [英] Can GNUPLOT dynamically prepare index labels?

问题描述

我正在GNUPLOT中绘制一个多图，并且为了节省空间，我只在其中一个图上绘制了轴标签.对于其他情节，我使用

I'm plotting a multiplot in GNUPLOT and in order to save space, I only plot the axis labels on one of the plots. For the other plots, I overwrite the tics-labels using

set ytics ("" -20, "" -15, "" -10, "" -5, "" 0, "" 5, "" 10, "" 15, "" 20)

对于这样的小规模，它可以手动执行.我可以使用内置的gnuplot(for循环)动态编写此范围"吗?

For a small scale like this, its doable manually. Can I use a gnuplot built-in (for-loop) to dynamically write this "range"?

推荐答案

是的，可以这样

numtics = 8

set macros

ticstring = '('

do for [i=0:numtics] {
    ticstring = ticstring.'"" '.(-20 + i*5).', '
}

ticstring = ticstring.'"" 20)'

set ytics @ticstring

在您的情况下，可能更简单的命令是

What may be simpler in your case would be the command

set ytics format "" 5

每5个抽签中会有一个空白标签.

Which will put a tic every 5 with a blank label.
