Chart Elements - X Axis Menu - X Axis Labels 3
We use steps to make some lables visible. We also override this in some of the lables.
This goes into the <head> of the page:
<script type="text/javascript" src="js/swfobject.js"></script>
<script type="text/javascript">
swfobject.embedSWF(
"open-flash-chart.swf", "my_chart",
"550", "400", "9.0.0", "expressInstall.swf",
{"data-file":"gallery/x-axis-labels-3.php"} );
</script>
This writes the chart into a div with id="my_chart",
right click and view source to see it in action,
[the tutorials have more details]

<?php

$title = new title( 'X Axis Labels Complex Example' );

//
// create an X Axis object

$x = new x_axis();
$x->set_stroke( 1 );
$x->set_colour( '#428C3E' );
$x->set_tick_height( 5 );
$x->set_grid_colour( '#86BF83' );
//
// here we place a tick on every X location:
//
$x->set_steps( 1 );
$x_labels = new x_axis_labels();
//
// show every other label
//
$x_labels->set_steps( 2 );
$x_labels->set_vertical();

$x_labels->set_size( 16 );
$tmp = array();
//
// these labels will inherit thier properties from $x_labels
// including 'visible' from the 'steps' value (which, for
// this example is 2) I have noted the inherited visible
// status for each item:
//
$tmp[] = 'one'; // visible
$tmp[] = 'two'; // invisible
$tmp[] = 'three'; // visible
$tmp[] = 'four'; // invisible
$tmp[] = 'five'; // visible
//
// these will override some or all of the
// inherited properties
//
$tmp[] = new x_axis_label('six', '#0000FF', 30, 270); // invisible
$tmp[] = new x_axis_label('seven', '#0000FF', 30, 270); // visible
$eight = new x_axis_label('eight', '#8C773E', 16, 315); // would be invisible, but:
$eight->set_visible(); // <-- FORCE this label visible
$tmp[] = $eight;
$tmp[] = new x_axis_label('nine', '#2683CF', 16, 0); // visible
//
// add the labels to the X Axis Labels object
//
$x_labels->set_labels( $tmp );
//
// Add the X Axis Labels to the X Axis
//
$x->set_labels( $x_labels );
//
// Add the X Axis object to the chart:
//
$chart->set_x_axis( $x );
echo $chart->toPrettyString();
