gnuplot -设置鼠标鼠标格式自定义格式

Question

set mouse command的文档显示了以下可能影响鼠标行为的格式，在这种情况下，使用正确的格式在左下角显示鼠标指针坐标：

0   real coordinates in  brackets e.g. [1.23, 2.45]
1   real coordinates w/o brackets e.g.  1.23, 2.45
2   x == timefmt                       [(as set by `set timefmt`), 2.45]
3   x == date                          [31. 12. 1999, 2.45]
4   x == time                          [23:59, 2.45]
5   x == date / time                   [31. 12. 1999 23:59, 2.45]
6   alt. format, specified as string   ""

但是，在两次尝试设置自定义格式之后，最终出现了错误line 0: wrong option

gnuplot -p -e 'set datafile separator ",";
            set xdata time;
            set timefmt "%m/%d/%y %H:%M";
            set format x "%d/%H:%M";
            set mouse mouseformat "mouse = %y/%m/%d %H:%M";
            set autoscale xfix;
            plot "rec-center-hourly.csv" using 1:2 every ::3::616 with lines'

gnuplot -p -e 'set datafile separator ",";
            set xdata time;
            set timefmt "%m/%d/%y %H:%M";
            set format x "%d/%H:%M";
            set mouse mouseformat "%y/%m/%d %H:%M";
            set autoscale xfix;
            plot "rec-center-hourly.csv" using 1:2 every ::3::616 with lines'

我也尝试过在交互式解释器中运行它：

└──> gnuplot -p
Terminal type set to 'wxt'
gnuplot> set datafile separator ",";
gnuplot> set xdata time;
gnuplot> set timefmt "%m/%d/%y %H:%M";
gnuplot> set format x "%d/%H:%M";
gnuplot> set mouse mouseformat "mouse = %y/%m/%d %H:%M";
gnuplot> set autoscale xfix;
gnuplot> plot "rec-center-hourly.csv" using 1:2 every ::3::616 with lines

└──> gnuplot -p
gnuplot> set datafile separator ",";
gnuplot> set xdata time;
gnuplot> set timefmt "%m/%d/%y %H:%M";
gnuplot> set format x "%d/%H:%M";
gnuplot> set mouse mouseformat "%y/%m/%d %H:%M";
gnuplot> set autoscale xfix;
gnuplot> plot "rec-center-hourly.csv" using 1:2 every ::3::616 with lines

然后显示图形，但在左下角是：mouse = %y/Argument list too long/7827416 %H:M而不是坐标。

我还注意到了另一个奇怪的行为，这里再次摘录自提到的页面：

1   real coordinates w/o brackets e.g.  1.23, 2.45
2   x == timefmt                       [(as set by `set timefmt`), 2.45]
3   x == date                          [31. 12. 1999, 2.45]

由于某种原因，set mouse mouseformat X命令的数字似乎发生了移位：

在我的机器中，使用的是timefmt而不是date

gnuplot -p -e 'set datafile separator ",";
            set xdata time;
            set timefmt "%m/%d/%y %H:%M";
            set format x "%d/%H:%M";
            set mouse mouseformat 3;
            set autoscale xfix;
            plot "rec-center-hourly.csv" using 1:2 every ::3::616 with lines'

和下面的集合real coordinates w/o brackets e.g. 1.23, 2.45而不是timefmt

gnuplot -p -e 'set datafile separator ",";
            set xdata time;
            set timefmt "%m/%d/%y %H:%M";
            set format x "%d/%H:%M";
            set mouse mouseformat 2;
            set autoscale xfix;
            plot "rec-center-hourly.csv" using 1:2 every ::3::616 with lines'    

Answer 1

根据v5.0文档，预定义的格式用于mouseformat

Use set mouse mouseformat "" to turn this string off again.
The following formats are available:
0 default (same as 1)
1 axis coordinates 1.23, 2.45
2 graph coordinates (from 0 to 1) /0.00, 1.00/
3 x = timefmt y = axis [(as set by ‘set timefmt‘), 2.45]
4 x = date y = axis [31. 12. 1999, 2.45]
5 x = time y = axis [23:59, 2.45]
6 x = date time y = axis [31. 12. 1999 23:59, 2.45]
7 format from ‘set mouse mouseformat‘, e.g. "mouse x,y = 1.23, 2.450"

我给出了一个例子，使用：

set timefmt '%Y-%m-%dT%H:%M:%S'
set mouse mouseformat 3
