在gnuplot中垂直堆疊的多插槽

Question

我想在gnuplot中垂直堆疊模式中繪製5個圖形。有許多水平（x軸共享）圖。我試圖調整他們的解決方案。但不知何故不起作用。這是代碼。

unset multiplot 

它給出了一個下面4個圖。代碼必須生成5個圖。 Generated image

原始圖像如下。我想刪除圖形之間的空白區域。 Original image

Gnuplot空間不足。您需要修復您的set size和set origin命令，以便您不在繪圖區域外繪圖。現在，您的SX=0.25意味着每個子圖的水平尺寸佔用可用空間的25％，因此只有4個子圖可以適合此設置。然後需要將第五個子圖放置在繪圖區之外。

還要注意，通過設置原點和大小，您將覆蓋已定義的multiplot layout。

通常，在做這種繪圖風格時，定義邊距而不是大小和原點可能是一個更好的主意。
