:: Home - Gallery - X Axis Labels

Info: Open Flash Chart 2 is out. Version 1.x and these pages will never disappear and the charts will continue working forever, but further development on 1.x has stopped. Take a look at version 2 here Open Flash Chart 2.

Gallery - X Axis Labels

Method: set_x_labels()

set_x_labels( $a )

$a array of strings to label each value of set_data( $a ).

Method: set_x_tick_size()

set_x_tick_size( $size )

$size of X axis label ticks in pixels.

Method: set_x_label_style()

set_x_label_style( int $size[, string $colour=''] [, integer $orientation] [, integer $step] [, string $grid_colour] )

$size integer, size in pixels of the X axis ticks.
$colour string, text colour.
$orientation integer, see X Axis Labels Orientation.
$step integer, see X Axis Labels Step.
$grid_colour, see X Axis Labels Step.

Method: set_x_axis_steps()

set_x_axis_steps( integer $step )

The chart elements will resize themselves to accomodate the X axis labels.

Create the flash object

open_flash_chart_object( 350, 150, 'http://'. $_SERVER['SERVER_NAME'] .'/open-flash-chart/gallery-data-8.php' );
?>

gallery-data-8.php

<?php

// generate some random data
srand((double)microtime()*1000000);

$tmp = array();
for( $i=0; $i<5; $i++ )

$g = new graph();
$g->set_data( $tmp );
$g->set_x_tick_size( 15 );
$g->set_x_labels( array('Mon','Tue','Wed','Thur','Fri') );
$g->set_x_label_style( 25, '#9933CC' );
$g->set_y_max( 10 );
$g->line( 2, '0x9933CC' );

echo $g->render();
?>

Remove X Axis Labels

In the next example I have removed X axis labels, by not calling the set_x_labels() method. The graph was made wider and the x_axis_tick_size() was set to 10 pixels.
