Warning: There is a bug when using the on-show animation. It screws up the tooltips.
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", "300", "9.0.0", "expressInstall.swf",
{"data-file":"gallery/candle-chart.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/candle-chart.php
<?php
include '../php-ofc-library/open-flash-chart.php';
$title = new title( date("D M d Y") );
$data = array();
for($i=0; $i<31; $i++ )
{
$high = (sin($i/2)*4) + 16;
$open = $high - 4 - (sin($i/2)*2);
$close = $high - 4 -(cos($i/2)*2);
$low = $high - 8;
if( abs($open-$close) < 0.3 )
{
// force a Doji
// (http://en.wikipedia.org/wiki/Candlestick_chart)
$open = $close;
}
$data[] = new candle_value(
number_format($high, 2),
number_format($open, 2),
number_format($close, 2),
number_format($low, 2));
}
$candle = new candle('#9933CC');
$candle->set_values($data);
$candle->set_tooltip('#x_label#<br>High: #high#<br>Open: #open#<br>Close: #close#<br>Low: #low#');
//$candle->set_on_show(new bar_on_show('drop', .9, 0));
$y = new y_axis();
$y->set_range( 0, 40, 10);
$chart = new open_flash_chart();
$chart->set_title( $title );
$chart->add_element( $candle );
$chart->set_y_axis( $y );
echo $chart->toPrettyString();
