Charts - Line Charts Menu - Advance Line Dot

Add different data to the graph.

Each dot gets its attributes from the line settings. For example, setting:

	$line_dot->set_dot_size( 3 );
actually sets each dots size attribute to 3. You can override these using dot_value( $value, $colour ) (search the PHP source code to see the methods avaible in this object)

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", "200",
"9.0.0", "expressInstall.swf",
{"data-file":"gallery/adv-line-dot.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]

$chart = new open_flash_chart();
$chart->set_title( new title'Advanced dot lines' ) );
$chart->set_y_axis$y );
//
// here we add our data sets to the chart:
//
$chart->add_element$line_dot );

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