GD Graph plot centered

toff has asked for the wisdom of the Perl Monks concerning the following question:

Hi, Thanks for your reply so far before I leap and try using Gnuplot I'd like to describe my problem a bit better. Basically when I plot a graph the picture is positioned exactly at the center of the grid instead of being justified to the left. The alignment command is mis-configered. Looking closely the plot and and the x axis look to be center aligned. This is why I only included the code section that covers setting alignment. Thanks Toff

code snippet
...
$my_graph = new GD::Graph::lines(500,400);

$size = scalar @resTimes;
my $skip = int ( $size / 7 );

$my_graph->set(
        x_label => 'Date',
        y_label => 'Price',
        title =>  'Pair: '.$myFname. '-'.$mySname .' Cor= '.$aCorr . '
+ Per= ' .$aPeriod,
        text => 'Line Graph',

        x_min_value => 0,
        y_min_value => 0,
        box_axis => 1,
        line_width => 1,
        x_label_skip => $skip,
        y_label_skip => 1,
        x_label_position => 1/2,
        y_label_position => 1/2,
        long_ticks => 1,
        transparent => 0,
        t_margin => 10,
        b_margin => 10,
        l_margin => 10,
        r_margin => 15,
);

Usually you will get a better response if you post a working snippet that describes the problem.... if you ask people to flesh out your code to make it run, they just skip to the next node. :-) I can't really say I understand your question, but remember, these GD graph modules are very basic; if you want alot of functionality in your graphs, you should look at the bigger graph modules, like Gnuplot and gnuplot. I usually go right to the Tk::Canvas when I want a special graph.... it gives you total control. I'm not really a human, but I play one on earth. Cogito ergo sum a bum	[reply]
