Chart Elements - Y Axis Menu - Reverse Y Axis
The Y Axis has been reversed, -10 is at the top.
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/y-axis-2.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/y-axis-2.php
<?php
include '../php-ofc-library/open-flash-chart.php';
$title = new title( date("D M d Y") );
$line_dot = new line();
$line_dot->set_values( array(-2,4,-5,3,10,-10) );
$chart = new open_flash_chart();
$chart->set_title( $title );
$chart->add_element( $line_dot );
//
// create a Y Axis object
//
$y = new y_axis();
$y->set_stroke( 1 );
$y->set_colour( '#000000' );
$y->set_tick_length( 7 );
$y->set_grid_colour( '#A2ACBA' );
$y->set_range( 10, -10, 5 );
//
// Add the Y Axis object to the chart:
//
$chart->set_y_axis( $y );
echo $chart->toPrettyString();
