你能帮我吗?我希望将一行类型更改为点线.我使用这些命令: gnuplot> set terminal png size 750,210 nocrop butt font "/usr/share/fonts/truetype/ttf-liberation/LiberationSans-Regular.ttf" 8 gnuplot> set output "/root/data.png" gnuplot> set xdata time gnuplot> set timefmt "%Y-%m-%d" gnuplot> set format x "%b %d" gnuplot> set ylabel "item1" gnuplot> set y2label "item2" gnuplot> set y2tics gnuplot> set datafile separator "|" gnuplot> plot "/root/results.txt" using 1:2 title "item1" w lines lt 4,"/root/results.txt" using 1:3 title "item2" with lines 但我总是得到洋红色线. 解决方法有几种方法可以使用set命令更改线条颜色:>定义线条样式: set style line 1 linetype 1 linecolor 7 set style line 2 linetype 1 linecolor rgb "#dd7700" plot x linestyle 1,x**2 linestyle 2 您必须明确指定使用哪种线条样式. set style line 1 linetype 1 linecolor 7 set style line 2 linetype 1 linecolor rgb "#dd7700" set style increment user plot x,x**2 >重新定义默认行类型(在4.6.0版中引入): set linetype 1 linecolor 7 set linetype 2 linetype 1 linecolor rgb "magenta" plot x,x**2 请注意,与线型不同,set linetype的重新定义是持久的;他们不受重置的影响.要重置它们,您必须使用set linetype 1 default. 因此,最小的绘图脚本可能如下所示: reset set terminal pngcairo dashed monochrome set output "/root/data.png" set xdata time set timefmt "%Y-%m-%d" set format x "%b %d" set datafile separator "|" set style data lines plot "/root/results.txt" using 1:2 linetype 1,"" using 1:3 linetype 3 (编辑:晋中站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
