Y軸右側的冗餘空間

Question

我試圖用GNU Plot繪製一些實驗數據的圖，但是我不知道如何去除Y軸和第一個樣本之間的冗餘填充/空間（左側第一樣品）：

代碼：

set terminal pngcairo size 800,800 enhanced font 'WenQuanYiZenHei,12' 
set title "All Elements" 
set xlabel "Sample" 
set ylabel "Element Amounts" 

set ytics nomirror 
set style fill transparent solid 0.5 noborder 
plot data u 2:xticlabels(1) w histograms title "K",\ 
    data u 3:xticlabels(1) w histograms title "Ca",\ 
    data u 4:xticlabels(1) w histograms title "Mg",\ 
    data u 5:xticlabels(1) w histograms title "Fe",\ 
    data u 6:xticlabels(1) w histograms title "Mn",\ 
    data u 7:xticlabels(1) w histograms title "Zn" 

數據：

| Sample |  K | Ca | Mg |  Fe | Mn | Zn | 
|--------+-------+-------+------+--------+-------+------| 
| -Ca 1U | 58800 | 4800 | 2700 | 222.5 | 28.0 | 30.0 | 
| -Ca 2U | 59000 | 5475 | 3200 | 105.5 | 29.5 | 35.0 | 
| -Mg 1U | 57600 | 12275 | 2900 | 92.0 | 45.5 | 37.0 | 
| -Mg 2U | 57200 | 13850 | 3200 | 266.0 | 59.5 | 39.0 | 
|--------+-------+-------+------+--------+-------+------| 
| -Ca 1D | 19700 | 1100 | 3400 | 1708.0 | 79.0 | 48.5 | 
| -Ca 2D | 20900 | 1025 | 3300 | 1812.0 | 102.5 | 54.5 | 
| -Mg 1D | 23200 | 3175 | 3200 | 312.0 | 49.5 | 61.0 | 
| -Mg 2D | 21800 | 4325 | 2300 | 2136.0 | 86.5 | 55.5 | 

Answer 1

這是因爲數據中的標題行。您可以跳過它

plot data every ::1 u 2: ... 

或者只是在將數據提供給gnuplot之前將其刪除。
