Gnuplot y-scale使用多點時

Question

我使用perl腳本解析出一些天氣數據，然後用gnuplot在3行乘2列顯示中繪製這些數據。除最後一張「累計降雨量」圖外，我的所有圖表似乎都能正常工作。該圖實際上是正確繪製的，但y尺度似乎使用「Minute Rainfall」圖的設置。有人可以看看我的gnuplot代碼，看看我可能會出錯嗎？謝謝你的幫助。

最後情節的規模是好的，但使用從以前的劇情ytic設置。只需在最後一個劇情中使用set ytics auto即可。

順便說一句：要在最後x上顯示24:00 -tic，請使用set xtics add ("24:00" "24:00")。

和許多你的設置是多餘的，請參閱下面的腳本減少：

set terminal wxt size 1500,750 
set size ratio 0.25 

unset key 
set xdata time 
set timefmt "%H:%M" 
set xrange ["00:00" : "24:00"] 
set xtics add ("24:00" "24:00") 
set format x "%H:%M" 
set xlabel "Time of Day" 
set style data lines 
set grid
