Question

我正在使用随附的脚本制作带有色条的3D图像。但是我不知道如何改变y轴的方式，使其2/3显示[0,250]，其余1/3显示[250：400]。这样，我想在较低的y值上进行缩放。我尝试了断开轴，但是它不能与污点一起使用，这也不是我想要的。我在考虑多图选项2x1 rowfirst，第一行有额外的空间，但是我做不到。

有人可以帮助我吗？

如果您只询问y轴刻度标签，而不是重新调整轴本身的缩放比例，那么下面是一个示例，该示例将间距为[0：250]的细间距标签与两个额外的300和400标签组合在一起。

set ytics 0, 10, 250
set ytics add (300, 400)
