How do I change font on GD graph title, x_label, y

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

Wise Monks, How can I change my Font(appearance) of the linespoints Graph title, X_label and y_label? The /font/arial.tf is not working. Please advise. Regards, Rakhee Here is my code snippet:

$mygraph->set(
    x_label     => 'Log_Date',
    y_label     => $y_label,
    x_label_skip => 30,
    x_labels_vertical => true,
    title       => $title,
    legend_placement => 'BL',
    legend_marker_height => 12,
    dclrs => [ qw(green blue red yellow brown orange) ],
) or warn $mygraph->error;
$mygraph->set_legend(@legend_keys);
$mygraph->set_title_font('/fonts/arial.tf', 24);
my $myimage = $mygraph->plot(\@data) or die $mygraph->error;

`'/fonts/arial.tf'` Are you sure that's where the font is located, i.e. in a directory `/fonts` immediately below the root directory "/" ...? (P.S.: I suppose with "GD graph" you mean GD::Graph)	[reply] [d/l] [select]

$mygraph->set_title_font('/fonts/arial.tf', 24); What do you get if you add this to the top of your program: `print 'Font ', -f '/fonts/arial.tf' ? 'found' : 'not found';` [download] Isn't the usual extension '.ttf', or is that only on Windows? Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

As other have pointed out, it seems likely that you're really asking about the GD::Graph module rather than GD and your problem is probably just that the file pathname in your script to the Arial font file does not match where that font actually lives on your machine.

Which module are you talking about? GD doesn't have a `set_title_font()` method.	[reply] [d/l]

Thank you all Monks. I am using GD::Graph::linespoints I tried $mygraph->set_title_font(GD::gdGiantFont); It does what I want for right now. Also, I don't think my fonts are in /fonts. I need to look for them. Thank u all for the wonderful support. Sometimes it can get lonely in the perl world of debugging. Regards, Rakhee	[reply]

Hi Anonymous Monk, I am using GD::Graph::linespoints I am using following $mygraph->set_title_font(GD::gdGiantFont); $mygraph->set_x_label_font(GD::gdLargeFont); $mygraph->set_y_label_font(GD::gdLargeFont); It works and changes the font for title and labels for me. ~Rakhee	[reply]
