use command line gnuplot to create two window that plots column V(1), V(2) and mAh(1), mAh(2)
echo "press enter to close"
gnuplot -e \
'set terminal wxt; plot "out.txt" using 1:2 title "V(1)" with lines, "" using 1:6 title "V(2)" with lines; '\
'set terminal wxt 1; plot "out.txt" using 1:5 title "mAh(1)" with lines, "" using 1:9 title "mAh(2)" with lines;'\
'pause -1;'
suppose out.txt and out2.txt with contents TIME SPEED and TIME ACCEL respectively:
gnuplot -e \
'set grid xtics ytics; set grid;'\
'set xlabel "time(us)";'\
'plot "out.txt" title "speed(rps)",'\
'"out2.txt" title "accel(rps2)";'\
'pause -1;'
- plot with lines
plot "out.txt" with lines
- plot with lines and points
plot "out.txt" with linespoint
