[Gnuplot-info] ionsphere's maps using Gnupot (again)

[Wesley R. <wes...@ya...>]

Dear,
   
  Thanks for answer my e-mail!
   
  With Gnuplot I am using this cookbook down:
  set xtics 5
  set ytics 5
  set mxtics 5
  set mytics 5
  set nogrid
  set xlabel "Longitude"
  set ylabel "Latitude"
  cd 'c:\bolsa'
  set title "mapa da ionosfera"
  #set surface
  set view map
  #set contour base
  set cntrparam levels incremental 50, 15, 300
  set clabel
  set dgrid3d 60,60,2
  set pm3d explicit
  set cbrange [0:80]      #scale size
  set yrange [-35:5]
  set xrange [-75:-35]
  set palette define ( 0 "blue", 1 "green", 2 "yellow", 3 "red" ) 
  splot 'brazil2pts.txt' using 1:2:0 with lines, 'map.dat' using ($4):($3):($5) with pm3d   
   
  Using this cookbook, I don’t see the Brazil’s contour again, only the surface interpolate and the scale. I don’t be able too, delimitate the interpolation’s area (-75/-30/-35/5).
  What’s function I can use? 
   
  Best Regards!
