[Gnuplot-info] Problems with terminal png

[Markus L. <ml...@cf...>]

Hi there,

I`ve got a problem with the png terminal.
When Im using this terminal all lines were plotted with the same width.
Is there a bug or am I doing something wrong.
    reset   
    unset key
    set polar
    set angle degrees
    set trange [0:360]
    unset zeroaxis
    set xrange [-0.002:0.002]
    set yrange [-0.002:0.002]
    set size square
    set output "Curtflux1.png"
    set terminal png transparent
    set grid polar 45 lt -1 lw 0.015
    set xtics axis nomirror
    set ytics axis nomirror
    unset border
    set xlabel "kg/s"
    set xtics ("0"
0,""0.00025,"0.0005"0.0005,""0.00075,"0.001"0.001,""0.00125,"0.0015"0.0015,""0.00175,"0.002"0.002)
    unset ytics 
    plot 'valve1fluxmod.dat' using 1:2000 w l lw 4 lt 1

I hope somebody could help me. Im not really used to gnuplot but trying
to get.
Regards,
Markus

Hard to tell, because you didn't include information about:

1) which version of gnuplot you're talking about
2) compiled how ("show version long" output would help)
3) running on what kind and version of operating system

At least the "+GD_PNG" terminal of a current version of gnuplot, using a 
current version of libgd and libpng, is quite capable of producing lines 
of different widths.
