Grafika:Floor function.svg

Graph of the floor function.

(My first decent-looking gnuplot-generated SVG.)

See Wikipedia graph-making tips.

Generated in gnuplot with the following script:

# Set square 1000×1000 SVG output and filename
# The font size (fsize) sets the size for the circles, too.
set terminal svg enhanced size 1000 1000 fname "Times" fsize 36
set output "floor.svg"

# Set the text value for missing entries in the data file, so we can plot a discontinuous function
set datafile missing "Skip"    

# Set y axis limits so the plot doesn't go right to the edges of the graph
set yrange [-3.5:3.5]
# Set x axis limits so the first and last points are hidden
set xrange [-3.5:3.5]

# No legend needed
set nokey

# Add lightly-colored axis lines
set yzeroaxis
set xzeroaxis

# Plot as lines and also points (circles)
plot "floor.dat" with lines
plot "floor.dat" with points 1 6

# Close the file (so I don't have to close gnuplot to view it)
set output

and data file:

floor.dat

#  X     Y1
   -3    -4
   Skip    
   -3    -3
   -2    -3
   Skip    
   -2    -2
   -1    -2
   Skip    
   -1    -1
   0     -1
   Skip    
   0     0 
   1     0 
   Skip    
   1     1 
   2     1 
   Skip    
   2     2 
   3     2 
   Skip    
   3     3 
   4     3 

Then I opened the resulting SVG file in Inkscape, changed the fill style for the circles (either blue or white fill), brought the plot lines to the top, and then brought the circles to the top (over the lines).
