Re: Two questions for GD::Graph

As for the grid, maybe you want long_ticks? (or x_long_ticks and y_long_ticks to set them separately)

I'm not sure if you can print the labels slanted (actually, I'm afraid you can't without hacking the source¹), but for long labels there's x_labels_vertical.

___

¹ the idea would be to change $angle in the following snippet:

        if (defined $text)
        {
            $self->{gdta_x_axis}->set_text($text);

            my $angle = 0;
            if ($self->{x_labels_vertical})
            {
                $self->{gdta_x_axis}->set_align('bottom', 'center');
                $angle = PI/2;
            }
            else
            {
                $self->{gdta_x_axis}->set_align('center', 'right');
            }
            $self->{gdta_x_axis}->draw($x - $self->{axis_space}, $y, $
+angle);
        }

Great! Both of these were exactly what I was looking for. Do you know how I can change the y_long_ticks colour or make the line dotted? Thank you, Kevin	[reply]

I don't think this is configurable, but - as usual - you could modify the sources. In this case, it looks like changing the following snippet (search for `"# Ticks and values for y axes"` in `axestype.pm`) `if ($self->{y_long_ticks}) { $self->{graph}->line( $x, $self->{bottom}, $x, $self->{top}, $self->{fgci} ) unless ($axis-1); }` [download] might have the desired effect... The `->line` method is from the GD module, so check its docs for what parameters are expected. The `$self->{fgci}` argument (foreground color) is presumably what you'd need to manipulate. See also `->setStyle` for dotted/dashed lines.	[reply] [d/l] [select]
