Question

以下为什么不起作用？（比较帖子底部的错误）

set terminal dumb
set style data lines

set datafile separator ","
set timefmt "%Y-%m-%d %H:%M:%S"

set xdata time
set xrange ['"2014-12-01 00:00:00"':'"2014-12-03 00:00:00"']

set format x "%m-%d\n%H:%M"

plot "<cat" using 1:2

数据：

2014-12-02 13:59:35,1
2014-12-02 13:59:57,2
2014-12-02 14:00:37,3
2014-12-02 14:00:43,4
2014-12-02 14:01:03,5
2014-12-02 14:01:22,6
2014-12-02 14:01:32,7
2014-12-02 14:01:37,8
2014-12-02 14:02:27,9
2014-12-02 14:04:18,10

输出：

Can't plot with an empty x range!

Answer 1

问题在于单引号内的双引号。你不需要他们两个。

set xrange ['2014-12-01 00:00:00':'2014-12-03 00:00:00']
plot "<cat" using 1:2

输出：
