Add different data to the graph.
Object: line_dot()
Method: line()
- line( int $line_width, string $colour, string $key_text[, int $size] )
Draws a line. This does not have tool tips. This is a bug, and at the moment I'm not sure if it needs fixing.
- line_dot( int $line_width, int $dot_size, string $colour, string $key_text[, int $key_size] )
- line_hollow( int $line_width, int $circle_size, string $colour, string $key_text[, int $key_size] )
To add more than one line of data to the graph, call the method set_data() with each line of data. Then set the line style with line()
For details of how we changed the key text styles, see Line and Key.
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/data-lines.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/data-lines.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(1,2,1,null,null,null,null,null) );
$chart = new open_flash_chart();
$chart->set_title( $title );
$chart->add_element( $line_dot );
echo $chart->toPrettyString();
