GraidleChart Create Graphic Charts

Php-mysql Course

- GraidleChart contains a free PHP graphing class that creates and displays several types of graphical diagrams: vertical or horizontal bar, line, spider, or pie graphs for incorporation into a website or application.
You must create an array (or several arrays) of numeric values (data points), and optional, another array with names /numbers for the other axis, in the same order to be associated with the values from the first array. Then you can use graidle class to generate a PNG chart of your data.
GraidleChart can auto adjust the scale and axis of the graph with positive and /or negative numbers.

1. Simple vertical bars that show the number of points of five names.

<?php
include('graidlechart/graidle.php');

// array with data points for each name
$data = array('N_1'=>12, 'N_2'=>23.5, 'N_3'=>8, 'N_4'=>9.8, 'N_5'=>21);

// set 2 numeric arrays, one with names (for x-axis), another with the points (y-axis)
$names = array_keys($data);
$points = array_values($data);

// create object of graidle class (define Title)
$graph = new graidle('Number of points');
$graph->setColor('#a7b8ed');
$graph -> setValue($points,'b'); // set series values, type of graph (b=bar)

$graph -> setSecondaryAxis(1,0); // display secondary x-axis grid
$graph -> setWidth(300); // graphic chart width
$graph -> setHeight(180); // graphic chart height
$graph -> setXValue($names); // add the names to x-axis
$graph->setDivision(10); // set division on scale axis
$graph->setBgCl('#efefef'); // background color
$graph -> setExtLegend(); // to show values to each bar

$graph -> create(); // create chart
$graph -> carry(); // outputs the graph

/*
 To save the chart, use carry2file() method, with: 'dir_name', 'file_name' (without extension)
 Ex.: save "graphic_chart_1.png" in directory "charts/"
 $graph->carry2file('charts/', 'graphic_chart_1');
*/
?>

Result:
2. Graphic chart with two lines that show the progress of the accesses, and visitors number in a week.

<?php
include('graidlechart/graidle.php');

// array with number of accesses, and visitors in a week
$acc = array(1200, 1558, 1678, 1500, 1625, 1480, 998);
$vis = array(310, 288, 350, 305, 455, 282, 255); 

// create object of graidle class (define Title)
$graph = new graidle('Accesses & Visitors');
$graph->setColor('#a7b8ed');
$graph -> setValue($acc,'l', 'Accesses'); // set line (l=line) for accesses (adding with legend)
$graph -> setValue($vis,'l', 'Visitors'); // set line for visitors

$graph -> setSecondaryAxis(1,0); // display secondary x-axis grid
$graph -> setWidth(450); // graphic chart width
$graph -> setHeight(180); // graphic chart height
$graph->setBgCl('#fefeff'); // background color

$graph -> create(); // create chart
$graph -> carry(); // outputs the graph
?>

Result:
3. Pie graphic chart that represents the number of tourist, by countries.

<?php
include('graidlechart/graidle.php');

// array with number of tourists, by countries
$data = array('USA'=>5500, 'Brazil'=>3000, 'France'=>2800, 'Spain'=>3700, 'Italy'=>1400); 

// set 2 numeric arrays, one with countries (for legend), another with tourists number
$cnt = array_keys($data);
$tor = array_values($data);

// create object of graidle class (define Title)
$graph = new graidle('Representation tourists 2012');
$graph->setColor('#a7b8ed');
$graph -> setValue($tor,'p'); // set pie chart (p=pie)

$graph -> setLegend($cnt); // to add a legend
$graph -> setExtLegend(2); // to display percentage, and numbers
$graph -> setWidth(420); // graphic chart width

$graph -> create(); // create chart
$graph -> carry(); // outputs the graph
?>
