Gnuplot datetime格式不起​​作用

Question

爲什麼以下不起作用？ （在所述柱的底部CF誤差）

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 

數據：

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 

輸出：

Can't plot with an empty x range! 

Answer 1

的問題是在雙引號單引號的內部。你不需要他們兩個。

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

輸出：
