使用Gnuplot时缺少终端"png“
使用Gnuplot时缺少终端"png“
提问于 2014-04-02 23:22:00
我使用的是Xubuntu 13.10，我是通过手动编译的方式安装gnuplot的。然而，当我测试"plot“的特性时，它得到了一个错误：
$ python PlotSccDistr.py
set terminal png size 1000,800
^
"scc.example.plt", line 16: unknown or ambiguous terminal type; type just 'set terminal' for a list如果我想设置终端png，但我在列表中找不到"png“：
$ gnuplot

png终端不可用的原因是它是一个基于libgd的终端，以及jpeg和gif。对于这些终端，gnuplot需要libgd版本的>= 2.0。为了让它可用，你必须先安装GD Graphics Library：
$ sudo apt-get install libgd2-dev然后安装gnuplot并检查png终端是否存在：
gnuplot> set terminal
Available terminal types:
...
gif GIF images using libgd and TrueType fonts
...
jpeg JPEG images using libgd and TrueType fonts
...
png PNG images using libgd and TrueType fonts
