Plotting Hints
The plot was produced with Gnuplot
commands
set xlabel 'Sequence Size (Thousands)'
set ylabel 'Computing Time (Seconds)'
set xrange [1:1100]
set logscale x
set logscale y
set data style linespoints
set key 100, 9
plot 'results' using 1:2 title "Introsort", 'results' using 1:3 title "Quicksort", 'results' using 1:4 title "Heapsort"
where results
is the file with the data (but no headings)
written by the program.
For displaying plots on web pages, insert before the plot
command
these commands to direct Gnuplot
to output the plot to a
file in PPM (portable pix map) form:
set term pbm small color
set output 'plot1.ppm
Then use the ppmtogif
image conversion utility
to convert the file to GIF format:
/usr/local/ppmtogif plot1.ppm >plot1.gif
