Question

这可能是一个错误，但我想我只需要设置我的环境。我在Ubuntu上。我尝试了包easyplot。当我将绘图保存到文件而不是终端时，它工作。我需要修理什么？

λ <Prelude Graphics.EasyPlot>: plot X11 sin

set term x11 persist; plot "plot1.dat" with lines
         ^
line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list

False
λ <Prelude Graphics.EasyPlot>: plot (PNG "test.png") sin
True

然后test.png在第二个命令之后是一个很好的图片，但第一个命令什么都不做。

Answer 1

你可以跑：

$ sudo apt-get install gnuplot-x11

在您的终端。

或者你可以在你的浏览器中找到“apt：gnuplot-x11”而不用引号自动修复你的问题（堆栈交换不让我把它变成蓝色。）

Answer 2

Ubuntu＆amp;的使用版本gnuplot本身会有所帮助。也尝试遵循gnuplot给出的建议。例如，在我的Arch Linux系统上，这个＆＃34;设置术语＆＃34;产生这种反应：

$ gnuplot

可以看出，＆＃34; x11＆＃34;是其他可用的终端类型之一。所以难怪plot X11 sin也有效。

我该如何设置这个包？
