在Perl中使用Gnuplot用不同颜色的实线

Question

I am trying to create a chart with two conditions :-

1) Solid lines 
2) Different colors .

Here is my code snippet :-

my $set = Chart::Gnuplot::DataSet->new(
        xdata => "words",
        ydata => "bits",
        title => "wordsvsbits",
        type => "matrix",
        font => "arial, 20",
        width => 7,
        style => "linespoints",
        linetype => "solid",
        imagesize  => "1.5,1.5",
        );

When i do this , I get solid lines with only one colour . If I dont give linetype , 1st line is a solid (Red color), 2nd line is dashed with different color and 3rd line is also dashed with a new color . Here I want to get new color for each line , but they should all be solid lines . Kindly , please help me .

Answer 1

Until version 4.6. this is controlled by set termoption solid . In Perl this should work with

my $chart = Chart::Gnuplot->new(
    termoption => "solid",
);

and without specifying the linetype .
