I use gnuplot to out put a png picture. Then the picture has been generate, but I cannot open it. What's the reason? I can open other png pictures on the ubuntu.
#! /usr/bin/gnuplot set terminal emf size 1280,960 font '/usr/common/fonts/simsun.ttc,14' set style data histograms set style fill transparent pattern 1 border set grid set title '有/无多AP协作下，AP吞吐量对比' set output 'BSS吞吐量对比曲线.png' set xlabel 'BSS' set ylabel 'AP 吞吐量/Mbps' #set xtics('BSS1' 0,'BSS2' 1,'BSS3' 2,'BSS4' 3,'BSS5' 4) set xrange [-1:5] set yrange [0:7000] plot 'hewthroughput.txt' using 2:xticlabels(1) title '无多AP协作',\ 'hewthroughput.txt' using 3:xticlabels(1) title '有多AP协作',\ 'hewthroughput.txt' using ($1-1):($2+200):($2) with labels notitle,\ 'hewthroughput.txt' using ($1-0.8):($3+200):($3) with labels notitle 1 Answer
set terminal emf means you're creating an EMF file. That you have set the filename to use .png doesn't mean that it will magically become a PNG file. If you want to make PNG files with gnuplot, use set terminal png.
