带有一个颜色框的Gnuplot多图 [英] Gnuplot multiplot with one colorbox

问题描述

我使用multiplot布局了3,1个地块。这三个图都具有相同的比例，因此我只想在右边距显示一个颜色框。但是，一旦我取消了前两个图的颜色框设置，三个图的大小就会不同。
谁能告诉我如何使用三个具有相同大小的地块来实现此目标吗？

解决方案

您必须设置一个固定的右边距，例如在屏幕0.85处设置边距。这会将图的右边界设置为图像尺寸的85％：<​​/ p>

  set multiplot layout 3,1 
 
在屏幕上设置边距0.85 
图x 
图x 
图x线调色板
未设置多图
设置输出
  

输出为4.6.3：

I have a layout of 3,1 plots using multiplot. All of the three plots have the same scales, so I just want to show one colorbox, on the right margin. However, once I unset the colorbox for the first two plot, the size of the three plot are different. Can anybody tell me how to implement this with the three plots have the same size?

解决方案

You must set a fixed right margin with e.g. set rmargin at screen 0.85. That sets the right border of the plot at 85% of the image size:

set multiplot layout 3,1

set rmargin at screen 0.85
plot x 
plot x
plot x linecolor palette
unset multiplot
set output

Output with 4.6.3:

Generic solution for fixed margins

If you want a layout with one row and three columns, can use the multiplot options margins and spacing to get three plots which have the same width:

set xlabel 'xlabel'
set ylabel 'ylabel'

set multiplot layout 1,3 margins 0.1,0.9,0.1,0.95 spacing 0.05

plot x

unset ylabel
plot x

plot x linecolor palette

unset multiplot
