GNUPlot在x2y2轴上绘制标签 [英] GNUPlot Draw label on x2y2 axes

问题描述

我想在使用自动缩放的绘图上放置标签.

I want to place a label on a plot which uses autoscale.

要使标签保持在同一位置，我想使用替代轴，该轴不使用自动缩放来获得绝对位置.

To keep the label at the same position i want to use alternative axis which don't use autoscale to get an absolute location.

如何选择设置标签"语句的使用轴?

How can I choose the uses axis of a "set label" statement?

set y2range [0:10]
set x2range [0:100]
set label "FooBar" at 10, 5

第3行:此处缺少某些内容. "axes x2y2"将不起作用(在图形标签功能中使用)

Line 3: something is missing here. "axes x2y2" wont work (used in plot label functions)

感谢您在这里帮助我:-)

Thanks for helping me out here :-)

推荐答案

可以使用不同的坐标系来放置标签(请参见交互式终端中的help coordinates):

There are different coordinate systems which you can use to place labels (see help coordinates in the interactive terminal):

• first，使用第一个轴(x，y)作为参考
• second，使用第二个轴(x2，y2)作为参考
• screen，相对于画布大小
• graph，相对于地块大小
• character，以字符为单位.

• first, uses the first axis (x, y) as reference
• second, uses the second axis (x2, y2) as reference
• screen, relative to the canvas size
• graph, relative to the plot size
• character, in character units.

因此，获取图内绝对位置的最佳方法是使用graph:

So the best way to get an absolute location inside the plot is with graph:

set label "FooBar" at graph 0.2, 0.2

您还可以混合使用坐标系:

You can also mix the coordinate systems:

set label "FooBar" at graph 0.2, screen 0.5
