小弟利用gnuplot画图,必须使用multiplot命令,在网上看到好多资料,但为什么我总是不成功呢,我的意思就是在同一张图里同时画多个图,代码如下 set te png small color picsize 420 180 set multiplot set size 0.5,0.5 set origin 0.0,0.5 plot sin(x) set size 0.5,0.5 set origin 0.0,0.0 plot 1/sin(x) unset multiplot set output '1.png' replot 结果能出来,但不是2张图,谁能告诉我那错了

我以前在Sco Unix下用c/c++开发过一段时间的程序。已经有三年没有编程了。现在想再重新熟悉一下。 我现在用的是linux,有什么工具推荐用来开发c/c++吗?另外如果我想所学的东西能够以后移植到其他的UNIX比如solaris。有什么建议吗? 谢谢
