gnuplot - 缩短多图中图之间的距离

Question

我必须绘制一个包含两列和五行的多重图。我已经绘制了该图，但我发现图之间的距离很大，我想减小它们。我使用了网站 ( http://www.gnuplot.info/demo_canvas/layout.html ) 中的最后一个示例编码(模板)。我尝试调整顶部和底部边距参数。如果我使用较小的值，x 轴的标签就会消失，并且图之间的距离会缩短。所以我必须使用大值。我只是想知道有没有其他方法可以让情节彼此更接近？我已经给出了下面的图的编码供您查看。我很高兴能就这个问题获得一些见解。提前致谢

我知道这是一个老问题，但也许可以用 set size 做一些事情增加每个图的大小(可选地，每个图可能需要 set origin)。否则，最好的选择是使用 set lmargin , set rmargin , set bmargin和set tmargin .

您可以使用set ?margin at ...设置相对于屏幕坐标的边距(而不是您所放置的形式中的字符坐标。这将允许您将绘图准确地放置在您想要的位置。请参阅 http://gnuplot.sourceforge.net/demo/margins.html
