Re: [SOLVED] change position of x-axis

[Vlăduţ Frăţiman]

After some more test's, seems to be a problem with gnuplot when
working with xzeroaxis and set/unset borders.
With latest patch proposed here , y axis it's draw very thin and it's
different from the width of x axis.
If ai set "linewidth" parameter, seems to be affected only y axis and
x axis remain untouch (because of lw parameter introduced with patch).
Look ok if linewidth it's set to "1", but if u want a different value,
then not work.
I think that it's better to modify this patch to get possibility to
set width of x axis like for y axis.
So line: fputs (plot_stream, "set xzeroaxis lt -1 lw 1;\n");
i change to this: fprintf (plot_stream, "set xzeroaxis lt -1 lw
%f;\n", axis_obj.linewidth);

Now i can set axis width for both of them with any convenient value,
using linewidth parameter and box off.
Alse i attached the patch to see everyone what changes i make.
