Hi,
I am trying to set the polaraxis environment to perform an antenna
radiation pattern graphic. The data are in degree and dB (so the y range
is -30:0).
I did that with theses gnuplot code :
set polar
set angle degrees
set size square
set grid polar
unset key
set trange [-pi:pi]
set rrange [-30:0]
set yrange [-30:30]
set xrange [-30:30]
set xtics axis nomirror
unset ytics
unset border
# {\312} degree symbol in postscript
set label "0{\312}" at 27,1
set label rotate by 30 "30{\312}" at 22,14
set label rotate by 60 "60{\312}" at 12,23
...
set label rotate by -30 "-30{\312}" at 22.5,-12
set term postscript eps enhanced mono size 8cm,8cm "Helvetica" 11
set output "graphic.eps"
plot "radiation_pattern.dat" w l lw 2
The coordinates are in a file with the index 0 is the x (degree) and the
index 1 is the y (radius) and are like this :
0 00
-1 00
-2 -01
-3 -02
-4 -04
-5 -07
...
-337 -22
-338 -24
-339 -30
-340 -30
...
-357 -02
-358 -01
-359 00
Do you think it's possible to plot a such graphic with pgfplots and how to do
this ?
Thanks,
Béatrice.
