Gnuplot中的軸標記命令不起作用？

Question

我有一個看起來不漂亮的多重陰謀，應該將它寫入物理論文。儘管我可以看到很多問題，但最令人沮喪的是Gnuplot似乎完全違背了我在一些子圖上設置的ytics命令。另外，第一個情節的我的軸標籤結束於第二個情節。我如何解決Gnuplot有自己的想法的這些問題，拒絕按照我所說的去做？如果放在plot命令之前

unset xtics 
unset ytics 
unset multiplot 

Answer 1

的ytic設置才能正常工作。這適用於所有設置。它必須出現在圖中，所有的設置都必須在各自的plot命令之前完成：

set ytics 1 
plot x 

這裏是你的腳本的改進版本：

reset 

datadir = 'C:\\Users\\cole1\\Documents\\MATLAB\\' 

set terminal postscript eps enhanced color size 10,5 
set output 'multiplot3.eps' 

set xtics font "Times-Roman, 20" 
set ytics font "Times-Roman, 18" 

set style line 1 lc rgb "red" pt 5 
set style line 2 lc rgb "blue" 

set style data lines 
unset key 

set multiplot layout 4,2 

set label 1 "(a)" at graph 0.01,0.9 
set ytics 1 
set xlabel "Log_{10} current density factor" 
set ylabel "Log_{10} percent efficiency" 
plot datadir.'logefficiency1.txt' ls 1 with lp 

set label 1 "(b)" 
set ytics 0.5 
set xlabel "Frequency (THz)" 
set ylabel "Intensity/freq. interval (arb.)" 
plot datadir.'spectralinfo4009.txt' ls 2 

set label 1 "(c)" 
set ytics 1 
plot datadir.'spectralinfo4018.txt' ls 2 

set label 1 "(d)" 
set ytics 15 
plot datadir.'spectralinfo4027.txt' ls 2 

set label 1 "(e)" 
plot datadir.'spectralinfo4036.txt' ls 2 

set label 1 "(f)" 
plot datadir.'spectralinfo4045.txt' ls 2 

set label 1 "(g)" 
set ytics 30 
plot datadir.'spectralinfo4054.txt' ls 2 

set label 1 "(h)" 
set ytics 300 
plot datadir.'spectralinfo4063.txt' ls 2 

unset multiplot 

的要點是：

1. 使用set multiplot layout 4,2自動更改大小和原點。
2. 如果它們沒有更改，則必須只設置一次xlabel和ylabel。
3. 同樣，只有在設置更改時，您才必須使用set ytics。
4. 通常情況下，如果啓用了自動縮放功能，則不得指定ytics的開始和結束，而只能指定增量。
5. 對於子圖標籤使用相對於實際繪圖的座標（graph 0.01,0.9）。並始終使用相同的標籤ID（1）。然後對於第二個和所有下面的圖，你必須只改變文本，使用舊的座標。然後，您可以在代碼中的一個位置對標籤位置進行微調。
6. 使用set style data lines
7. 使用線型
8. 使用unset key隱藏的傳說。
