在C中绘制图表 [英] Plotting Graph in C
问题描述
是否可以将图形绘制为我在C中的程序输出?它可以是简单的图形,例如二次曲线,例如
或两个变量之间的相关性。
谢谢

当然,但不是没有使用标准C的扩展( comp.lang.c中唯一的
主题。请参考OS /实现特定的
新闻组。

不写:void main(...)
不使用gets()
不投回报malloc的值()
不要fflush(stdin)

当然。只需输出一个PostScript格式的文本文件,即绘制
图表。

你可以使用外部程序gnuplot。

再见
Is it possible to plot the graph as an output of my program in C? It can be
a simple graph as quadratic curves for example
or a correlation between 2 variables only.
Thanks

Sure, but not without using extensions to standard C (the one and only
topic in comp.lang.c). Please refer to an OS/implementation specific
newsgroup.

do not write: void main(...)
do not use gets()
do not cast the return value of malloc()
do not fflush( stdin )

Sure. Just output a text file in PostScript format that plots
the graph.

you can use an external program as gnuplot .
