We will start with a simple line graph.
|

</p><pre class="programlisting"><?php
|

//Include the code
|
|
|
6 |
require_once 'phplot.php';
|
|
|
7 |
|
|
|
8 |
//Define the object
|
|
|

$plot = new PHPlot();
|
|
|
10 |
|
|
|
11 |
//Define some data
|
|
|
12 |
$example_data = array(
|
|
|
13 |
array('a',3),
|
|
|
14 |
array('b',5),
|
|
|
15 |
array('c',7),
|
|
|
16 |
array('d',8),
|
|
|
17 |
array('e',2),
|
|
|
18 |
array('f',6),
|
|
|
19 |
array('g',7)
|
|
|
20 |
);
|
|
|
21 |
$plot->SetDataValues($example_data);
|
|
|
22 |
|
|
|
23 |
//Turn off X axis ticks and labels because they get in the way:
|
|
|
24 |
$plot->SetXTickLabelPos('none');
|
|
|
25 |
$plot->SetXTickPos('none');
|
|
|
26 |
|
|
|
27 |
//Draw it
|
|
|
28 |
$plot->DrawGraph();
|
|
|
29 |
</pre><p>
|
|
|
30 |
|
|
|
31 |
</p><p>
|
|
|
32 |
|
|
|
33 |
And that's it! What we get is the following graph:
|
|
|
34 |
|
|
|
35 |
</p><div class="informalfigure"><div class="mediaobject"><img src="examples/qs1.png" alt="Simple line graph" /></div></div><p>
|
|
|
36 |
</p><p>
|
|
|
37 |
That's a great start, but now we would like to specify the width and height
|
|
|
38 |
of the image, and add some titles.
