This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Real-tetration.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

Plotting with gnuplot

It is possible to plot this in gnuplot with following commands:

set grid
set xr[-4:4]
set yr[-5:15]
set yzeroaxis linetype 7 linewidth 1.5
set xzeroaxis linetype 7 linewidth 1.5
tet(a,n)=(n<0)?((n<-1)?(log(tet(a,n+1))/log(a)):(1.0+((2*log(a))/(1+log(a)))*n-((1-log(a))/(1+log(a)))*n**2)) :(a**tet(a,n-1.0)) 
e=exp(1)
set xtic 1
set ytic 1
plot tet(e,x)

Above commands can be used to make an .svg version of the plot.
