Chart Elements - X Axis Labels 3
Object: x_axis_label( $text, $colour, $size, $rotate )
Parameters
- $text
Label text
- $colour
HTML Hex colour.
- $size
Font size in pixels
- $rotate
String can be one of "vertical" "diaganol" or "horizontal"
Methods:
- set_text( $text )
- set_colour( $colour )
- set_size( $size )
- set_rotate( $rotate )
- set_vertical()
- set_visible()
This overrides any previous attempt to make this label invisible. The parent
object (x_axis_labels) has a 'steps' attribute that makes some labels invisible,
use this to make them visible again.
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]

//
// 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_colour( '#ff0000' );
$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, 'vertical'); // invisible
$tmp[] = new x_axis_label('seven', '#0000FF', 30, 'vertical'); // visible
$eight = new x_axis_label('eight', '#8C773E', 16, 'diagonal'); // would be invisible, but:
$eight->set_visible(); // <-- FORCE this label visible
$tmp[] = $eight;
$tmp[] = new x_axis_label('nine', '#2683CF', 16, 'horizontal'); // 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();
