gnuplot圖例重疊圖

Question

本質上，我遇到的問題是圖例與我試圖繪製的gnuplot圖重疊，如下圖所示。

以下是我使用繪製數據的命令。

> set log y 
> plot "datafile1.txt" using 2:4 with lines, 
    "datafile1.txt" using 2:6 with lines, 
    "datafile2.txt" using 2:4 with lines, 
    "datafile2.txt" using 2:6 with lines 

以下是我用來繪製數據的數據文件1的一部分。

Dimension: 259 Timing: 36111 seconds, 9 seconds 
Dimension: 260 Timing: 37860 seconds, 9 seconds 
Dimension: 261 Timing: 39477 seconds, 6 seconds 
Dimension: 262 Timing: 41215 seconds, 5 seconds 
Dimension: 263 Timing: 41827 seconds, 5 seconds 
Dimension: 264 Timing: 42738 seconds, 11 seconds 
Dimension: 265 Timing: 42972 seconds, 14 seconds 
Dimension: 266 Timing: 44138 seconds, 10 seconds 
Dimension: 267 Timing: 45210 seconds, 11 seconds 
Dimension: 268 Timing: 46508 seconds, 9 seconds 
Dimension: 269 Timing: 51120 seconds, 15 seconds 
Dimension: 270 Timing: 49352 seconds, 6 seconds 
Dimension: 271 Timing: 50456 seconds, 9 seconds 
Dimension: 272 Timing: 52379 seconds, 16 seconds 
Dimension: 273 Timing: 52354 seconds, 16 seconds 

以下是我用來繪製數據的數據文件2的一部分。

Dimension: 269 Timing: 32507 seconds, 2 seconds 
Dimension: 270 Timing: 33064 seconds, 4 seconds 
Dimension: 271 Timing: 33590 seconds, 6 seconds 
Dimension: 272 Timing: 33703 seconds, 3 seconds 
Dimension: 273 Timing: 34616 seconds, 3 seconds 
Dimension: 274 Timing: 36113 seconds, 4 seconds 
Dimension: 275 Timing: 36477 seconds, 4 seconds 
Dimension: 276 Timing: 37000 seconds, 2 seconds 
Dimension: 277 Timing: 37872 seconds, 3 seconds 
Dimension: 278 Timing: 42290 seconds, 6 seconds 
Dimension: 279 Timing: 39862 seconds, 7 seconds 
Dimension: 280 Timing: 40184 seconds, 7 seconds 
Dimension: 281 Timing: 41229 seconds, 4 seconds 
Dimension: 282 Timing: 43221 seconds, 3 seconds 
Dimension: 283 Timing: 42706 seconds, 7 seconds 

任何幫助或建議如何克服這將不勝感激。

Answer 1

如果你想完全關閉它：

gnuplot> set nokey 

如果要移動的傳說，你可以做到這一點與

gnuplot> set key left top 

將它移動到左上角。如果你想給線路中的傳說更有意義的名稱，生成的情節時，使用title關鍵字：

gnuplot> plot "datafile1.txt" using 2:4 with lines title "data", 
.... 

Answer 2

你可以移動圖例的繪圖區域外，那麼他們肯定不會重疊：

gnuplot> set key outside 

看到這裏就傳說或鍵的位置有更多的選擇： http://gnuplot.sourceforge.net/docs_4.2/node192.html

Answer 3

可以通過提供一組座標控制鍵的位置：

set key at 25., 5000. 

這些值對應於數據座標系。或者，你可以指定座標圖：

set key at graph 0.1, 0.9 

（接近頂部偏左的位置）。
