Multiple Line Graph

[benchew0904]

Anyone can help me with plotting of multiple line graph in php.

 

I have researched on multiple line graph online and  I would like to plot the graph by taking data from my database but the example below is inserting the graph data manually.

Anyone can teach me how to use a for loop inside an array?

 

<?php
//Include the code
require_once 'phplot.php';

//Define the object
$plot = new PHPlot(800,600);

//Set titles
$plot->SetTitle("A 3-Line Plot\nMade with PHPlot");
$plot->SetXTitle('X Data');
$plot->SetYTitle('Y Data');

//Define some data
$example_data = array(
     array('a',3,4,2),
     array('b',5,3,1),  
     array('c',7,2,6),
     array('d',8,1,4),
     array('e',2,4,6),
     array('f',6,4,5),
     array('g',7,2,3)
);
$plot->SetDataValues($example_data);

//Turn off X axis ticks and labels because they get in the way:
$plot->SetXTickLabelPos('none');
$plot->SetXTickPos('none');

//Draw it
$plot->DrawGraph();
?>

You don't make a for loop INSIDE an array, you make an array IN foor loop.

 

 

foreach(range('a', 'g') as $letter) {

$example_data = array(

    array($letter,3,4,2)

);

}

From your example, "array($letter,3,4,2)", is I want to just a for loop for the following data, is it possible?
