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 dont see the Brazils contour again, only the surface interpolate and the scale. I dont be able too, delimitate the interpolations area (-75/-30/-35/5).
Whats function I can use?
Best Regards!
