Any graph plotting tool better than GNU plot?
提问by Abhishek
I have used GNU-plot for quite a long time and the thing I didn't like about it the quality of graph it produces.
我已经使用 GNU-plot 很长时间了，但我不喜欢它生成的图形质量。
I admire the ease with which we can plot graphs in gnu-plot, but i wished that the resultant graph was better in terms of quality. For example: the thickness of lines, color quality etc..
我很欣赏我们可以轻松地在 gnu-plot 中绘制图形，但我希望生成的图形在质量方面更好。例如：线条粗细、颜色质量等。
So is there any tool that retains the ease-of-use of GNU PLOT but eliminates the quality issues?
那么有没有什么工具既保留了 GNU PLOT 的易用性又消除了质量问题呢？

If you want another tool than gnuplot, then you are using it wrongly. I agree, the default colors and settings do not look that pretty, but you can so easily tweak it in your definition file ~/.gnuplot
如果您想要其他工具而不是gnuplot，那么您使用它是错误的。我同意，默认颜色和设置看起来不那么漂亮，但是您可以在定义文件中轻松调整它~/.gnuplot
set macros
png="set terminal png size 1800,1800 crop enhanced font \"/usr/share/fonts/truetype/times.ttf,30\" dashlength 2; set termoption linewidth 3"
eps="set terminal postscript fontfile \"/usr/share/fonts/truetype/times.ttf\"; set termoption linewidth 3;
set style line 1 linecolor rgb '#de181f' linetype 1 # Red
set style line 2 linecolor rgb '#0060ae' linetype 1 # Blue
set style line 3 linecolor rgb '#228C22' linetype 1 # Forest green
set style line 4 linecolor rgb '#18ded7' linetype 1 # opposite Red
set style line 5 linecolor rgb '#ae4e00' linetype 1 # opposite Blue
set style line 6 linecolor rgb '#8c228c' linetype 1 # opposite Forest green
Sample script:
示例脚本：
@png
set output "output.png"
plot x ls 1, -x ls 2, x**3 ls 3
And you have quite a nice graph already. Tweak linewidthand fontsizea bit, and you can do better than you would ever obtain with Excel.
你已经有了一个很好的图表。调整linewidth和fontsize一点，你可以做得比你会不会用Excel获取。

You could give R a try. R has different graph plotting libraries. And it's very well explained in this SO question here - Relationship between plotting packages in R
你可以试试R。R 有不同的图形绘图库。这在这个 SO 问题中得到了很好的解释 - R中绘图包之间的关系

You may give a try to ctioga2: http://ctioga2.sourceforge.net. I wrote it because I was unsatisfied with gnuplot. It does not have all gnuplot features, but in terms of graph quality, it does much better.
你可以试试ctioga2：http://ctioga2.sourceforge.net 。我写它是因为我对 gnuplot 不满意。它没有所有 gnuplot 功能，但在图形质量方面，它做得更好。
To migrate from gnuplot, you may be interested in the gnuplot versus ctioga2pages.
要从 gnuplot 迁移，您可能对gnuplot 与 ctioga2页面感兴趣。
