Add different data to the graph.
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()
Note: Please, make your charts pretty! This ugly chart simply shows
how to set all of the parameters.
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-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/data-lines-2.php
<?php
include '../php-ofc-library/open-flash-chart.php';
// generate some random data
srand((double)microtime()*1000000);
$data_1 = array();
$data_2 = array();
$data_3 = array();
for( $i=0; $i<9; $i++ )
{
$data_1[] = rand(1,6);
$data_2[] = rand(7,13);
$data_3[] = rand(14,19);
}
$default_dot = new dot();
$default_dot->size(5)->colour('#DFC329');
$line_dot = new line();
$line_dot->set_default_dot_style($default_dot);
$line_dot->set_width( 4 );
$line_dot->set_colour( '#DFC329' );
$line_dot->set_values( $data_1 );
$line_dot->set_key( "Line 1", 10 );
$default_hollow_dot = new hollow_dot();
$default_hollow_dot->size(5)->colour('#6363AC');
$line_hollow = new line();
$line_hollow->set_default_dot_style($default_hollow_dot);
$line_hollow->set_width( 1 );
$line_hollow->set_colour( '#6363AC' );
$line_hollow->set_values( $data_2 );
$line_hollow->set_key( "Line 2", 10 );
$star = new star();
$star->size(5);
$line = new line();
$line_hollow->set_default_dot_style($star);
$line->set_width( 1 );
$line->set_colour( '#5E4725' );
$line->set_values( $data_3 );
$line->set_key( "Line 3", 10 );
$y = new y_axis();
$y->set_range( 0, 20, 5 );
$chart = new open_flash_chart();
$chart->set_title( new title( 'Three lines example' ) );
$chart->set_y_axis( $y );
//
// here we add our data sets to the chart:
//
$chart->add_element( $line_dot );
$chart->add_element( $line_hollow );
$chart->add_element( $line );
echo $chart->toPrettyString();
