gnuplot-将鼠标设置为自定义格式

set mouse

的文档显示了可能影响鼠标行为的以下格式，在这种情况下，在左下角显示鼠标指针坐标时使用了正确的格式：

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   ""

但以下两次尝试设置自定义格式的结果是错误的

第0行：错误的选项

：

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'

我也试过从交互式解释器运行它：

└──> 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：

鼠标=%y/参数列表太长/7827416%H:M

而不是坐标

我还注意到了另一个奇怪的行为，这里是上述页面的摘录：

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]

似乎由于某种原因，

set mouse mouseformat X

命令的数字发生了移动：

在我的机器中，以下设置

timefmt

和not

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'

以及以下不带括号的

真实坐标集，例如1.23、2.45

和非

timemt

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'

根据v5.0文档，预定义格式适用于

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"

我举了一个例子：

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

如果我用

设置鼠标格式3

尝试，我也会得到

错误选项

错误。

有几件事：要更改左下角显示的值，请使用

设置鼠标格式

，

设置鼠标格式

更改单击某处时显示的标签的外观。接下来，文档说，这个格式被赋予了

sprintf

，它不理解时间格式，只需要两个格式说明符，用于

x

和

y

。关于转换：在4.6文档中，它说，

为您提供了

timemt

。请注意，您链接的文档来自4.2！你好，克里斯托夫，所以在

格式中没有办法让左下角有%y/%m/%d%H:%m“

格式？恐怕没有。你试过使用

？`这应该给你与轴相同的格式。也许这是一个选项。它给了我
