Charts - Area Charts Menu - Area Hollow Chart

Make an area chart.

Note to self: I must write a tutorial on how to use point objects

Documentation: area_hollow, inherits from area_line.

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/area-hollow.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]

gallery/area-hollow.php
<?php


$data 
= array();

for( 
$i=0$i<6.2$i+=0.2 )
{
  
$tmp sin($i) * 1.9;
  
$data[] = $tmp;
}

include 
'../php-ofc-library/open-flash-chart.php';

$chart = new open_flash_chart();
$chart->set_title( new title'Area Chart' ) );

//
// Make our area chart:
//
$area = new area();
// set the circle line width:
$area->set_width);
$area->set_default_dot_style( new hollow_dot() );
$area->set_colour'#838A96' );
$area->set_fill_colour'#E01B49' );
$area->set_fill_alpha0.4 );
$area->set_values$data );

// add the area object to the chart:
$chart->add_element$area );

$y_axis = new y_axis();
$y_axis->set_range( -22);
$y_axis->labels null;
$y_axis->set_offsetfalse );

$x_axis = new x_axis();
$x_axis->labels $data;
$x_axis->set_steps);

$x_labels = new x_axis_labels();
$x_labels->set_steps);
$x_labels->set_vertical();
// Add the X Axis Labels to the X Axis
$x_axis->set_labels$x_labels );



$chart->add_y_axis$y_axis );
$chart->x_axis $x_axis;

echo 
$chart->toPrettyString();
To see the data produced : gallery/area-hollow.php, then 'view source'.
