Question

我试图在gnuplot中以垂直堆叠的模式绘制5个图形。有许多水平（x轴共享）图形。我试图调整他们的解决方案。但不知何故不起作用。这是代码。

set key bottom center

下面给出了4个图表中的一个。代码必须生成5个图表。 Generated image

原始图片如下。我想删除图表之间的空白区域。 Original image

Answer 1

Gnuplot空间不足。您需要修复set size和set origin命令，以便不在绘图区域之外绘图。现在，您的SX=0.25表示每个子图的水平尺寸占可用空间的25％，因此只有4个子图可以适合此设置。然后需要将第五个子图放置在绘图区域之外。

另请注意，通过设置原点和尺寸，您将覆盖已定义的multiplot layout。

通常，在进行这种绘图风格时，最好定义边距而不是尺寸和原点。
