The subroutine _thaw doesn't localizes $\ prior to writing data to the
temporary file. That is the following code doesn't work as expected:
use Chart::Gnuplot;
$\ = "\n";
my $chart = Chart::Gnuplot->new(output => "test.png");
my $data = Char::Gnuplot::DataSet->new(xdata => [0..10], ydata =>
[0..10], style => "lines");
$chart->plot2d($data);
In this example all lines in temporary data file will be separated by
blank lines and gnuplot will not join corresponding points. As the
result, the output doesn't contain any line.
Possible solution: add "local $\ = undef;" at the beginning of _thaw
subroutine.
