Bug #81688 for Chart-Graph: Should set font and encoding preliminarily

Subject:

Should set font and encoding preliminarily

The following works well: gnuplot({'title' => 'Google positions', 'xdata' => 'time', 'timefmt' => '%Y-%m-%d', 'x-axis label' => 'Date', 'y-axis label' => 'Position', 'output file' => undef, 'output type' => 'png', 'yrange' => "[$min:$max] reverse", 'extra_opts' => join "\n", ('set encoding utf8', 'set format x "%d-%b-%Y"', 'set ytics 1', 'set xtics 86400', 'set term png font "Arial,12"', 'set key font "/usr/local/lib/X11/fonts/webfonts/arial.ttf"', 'unset mxtics'), }, @graphs); But when I replace 'x-axis label' and 'y-axis label' with strings in Russian language it shows a nonsense in the labels. I am unsure but suppose that extra_opts setting Russian encoding runs after setting the labels and thus has no effect.

The boss commanded me to fix this bug. So I am going to dig into Chart::Graph::Gnuplot code and do it.

No, it is not a Chart::Graph::Gnuplot bug. The following works well: gnuplot({'encoding' => 'utf8', 'title' => 'Позиции Google', 'xdata' => 'time', 'timefmt' => '%Y-%m-%d', 'x-axis label' => 'Дата', 'y-axis label' => 'Позиция', 'output file' => undef, 'output type' => 'png', 'yrange' => "[$min:$max] reverse", 'extra_opts' => join "\n", ('set fontpath "/usr/local/lib/X11/fonts/webfonts"', 'set format x "%d-%b-%Y"', 'set xtics font "/usr/local/lib/X11/fonts/webfonts/arial.ttf"', 'set ytics font "/usr/local/lib/X11/fonts/webfonts/arial.ttf"', 'set ytics 1', 'set xtics 86400', #'set term png font "Arial,12"', 'set term png font "/usr/local/lib/X11/fonts/webfonts/arial.ttf"', 'set key font "/usr/local/lib/X11/fonts/webfonts/arial.ttf"', 'set title font "/usr/local/lib/X11/fonts/webfonts/arial.ttf"', 'unset mxtics'), }, @graphs);
