如何保持gnuplot-x11圖形視窗打開直到手動關閉？

例如，這會使gnuplot-x11圖形視窗保持打開狀態，直到按下某個鍵：

gnuplot -e "plot \"file\" ; pause -1 \"text\""

如何保持打開直到手動關閉？

使用-por--persist選項：

gnuplot --persist -e 'plot sin(x)'

這將保持視窗打開，直到手動關閉。從手冊頁：

-p,  --persist  lets  plot  windows  survive after main gnuplot program
               exits.

你最好pause mouse close在腳本末尾使用。這樣，您將可以使用滑鼠和各種鍵綁定來控制繪圖，而無需任何額外的輪詢，與--persistor不同reread。

預設鍵綁定包括：

<B1> doubleclick   send mouse coordinates to clipboard (pm win wxt x11)
<B2>               annotate the graph using `mouseformat` (see keys '1', '2')
                   or draw labels if `set mouse labels is on`
<Ctrl-B2>          remove label close to pointer if `set mouse labels` is on
<B3>               mark zoom region (only for 2d-plots and maps)
<B1-Motion>        change view (rotation); use <Ctrl> to rotate the axes only
<B2-Motion>        change view (scaling); use <Ctrl> to scale the axes only
<Shift-B2-Motion>  vertical motion -- change xyplane
<B3-Motion>        change view (azimuth)
<wheel-up>           scroll up (in +Y direction)
<wheel-down>         scroll down
<shift-wheel-up>     scroll left (in -X direction)
<shift-wheel-down>   scroll right
<Control-WheelUp>    zoom in on mouse position
<Control-WheelDown>  zoom out on mouse position
<Shift-Control-WheelUp>    pinch on x
<Shift-Control-WheelDown>  expand on x

Escape          `builtin-cancel-zoom` cancel zoom region
