GnuPlot
=======
A PHP Library for using GnuPlot
This is the output of the `demo/write.php`:
Requirements
============
You need to have a server with `gnuplot` installed and the safe mode
disabled (to be able to run `proc_open()`)
Usage
=====
There is examples in the `demo/` directory.
You can create a graph and populate it like this:
```php
setGraphTitle('Demo graph');
// Adding three points to the first curve
$plot
->setTitle(0, 'The first curve')
->push(0, 4)
->push(1, 5)
->push(2, 6)
;
// Adding three points on the other curve
// (with index 1)
$plot
->setTitle(1, 'The first curve')
->push(0, 8, 1)
->push(1, 9, 1)
->push(2, 10, 2)
;
```
You can then save it to a file, have a look to `write.php` for example:
```php
writePng('out.png');
```
Or render it directly into a browser, you can try `out.php` for
example:
```php
get();
```
Or display it on the screen (useful with CLI scripts), run the
`demo.php` script for example:
```php
display();
```
Or display it, and re-feed it in real time (with CLI scripts), you can
run `realTime.php` for example:
```php
refresh();
```
API
===
* `push($x, $y, $index=0)`, add a point to the $index-nth curve
* `display()`, renders the graph on the screen (asuming you are using
it as a CLI with an X Server
* `refresh()`, same as `display()`, but will replot the graph after
the first call
* `get()`, gets the PNG data for your image
* `writePng($filename)`, write the data to the output file
* `setTitle($index, $title)`, sets the title of the $index-nt curve
* `setGraphTitle($title)`, sets the main title for the graph
* `setXLabel($text)`, sets the label for the X axis
* `setYLabel($text)`, sets the label for the Y axis
* `setXRange($min, $max)`, set the X min & max
* `setYRange($min, $max)`, set the Y min & max
* `setWidth($width)`, sets the width of the graph
* `setHeight($height)`, sets the width of the graph
* `addLabel($x, $y, $text)`, add some label at a point
