绘图在Octave 4.0.0(Windows 7 64位)中不起作用 [英] Plot doesn't work in Octave 4.0.0 (Windows 7 64-bit)

问题描述

我正试图让Plot在Octave Windows 7(64位)上工作.我尝试过的事情:

I'm trying to get Plot working for Octave Windows 7 (64 bit). Things I have tried:

1. 试图将graphics_toolkit更改为gnuplot或fltk.请参见绘图"窗口无响应
2. 我尝试卸载并重新安装Octave.
3. 我试图在Octave目录中安装最新版本的gnuplot.
4. pkg rebuild -noauto oct2mat(在八度重新启动之前或之后没有帮助)

1. Tried changing the graphics_toolkit to gnuplot or fltk. See Plot window not responding
2. I have tried uninstalling and re-installing Octave.
3. I have tried to install the latest version of gnuplot in the Octave Directory.
4. pkg rebuild -noauto oct2mat (didn't help before or after octave restart)

光标移动到下一行(没有">>"，就像在等待命令运行一样)，但是图形窗口根本没有显示，我必须按Ctr-C几次才能强制八度退出.

The cursor moves to the next line (without ">>", as if waiting for the command to run), but the figure window doesn't show at all, I have to press Ctr-C several times to force Octave to quit.

代码:

x = linspace(0,1,10)
y = x.^2
plot(x,y);

请提出是否可以尝试其他建议.

Please suggest if I can try something else.

八度版本:4.0.0，可在Windows 7 64位专业版便携式计算机上运行.

Octave version : 4.0.0, running on a laptop, Windows 7 64-bit Professional.

推荐答案

我将注释重写为答案. 在Windoze上的GNU Octave中首次进行绘制时，存在长时间的延迟是一个已知的问题: http://savannah .gnu.org/bugs/?45458

I rewrite the comment as answer. A long delay when plotting for the first time in GNU Octave on Windoze is a known problem: http://savannah.gnu.org/bugs/?45458

其原因是fontconfig缓存必须构建一次.之后，绘图应照常进行.

The reason for this is that the fontconfig cache has to be build once. After that plotting should be fast as usual.
