Downloads](https://poser.pugx.org/samchristy/piechart/d/monthly)](https://packagist.org/packages/samchristy/piechart) 4 | 5 | A reasonably efficient* class for drawing pie charts with ImageMagick or GD in PHP. Intended as a 6 | learning exercise for using the NetBeans IDE and the Xdebug profiler and debugger. The code is 7 | available under the [GNU GPL v3.0](http://www.gnu.org/licenses/gpl-3.0.html), so feel free to use it 8 | with attribution. I recommend using the Imagick version, `PieChartImagick` over the GD version, 9 | `PieChartGD`. 10 | 11 | ### Demonstration ### 12 | Below is the code required to generate a pie chart and echo it to the client's browser. The example 13 | uses the method `outputPNG()` to tell the browser to render the image. Alternatively, the function 14 | `forceDownloadPNG()` can be used to instruct the browser to bring up the save dialog. 15 | 16 | ### Documentation ### 17 | [View the documentation](http://samchristy.github.com/PieChart/documentation/index.html) 18 | (generated with [ApiGen](http://apigen.org/)). 19 | 20 | #### Installation #### 21 | [Use Composer](https://packagist.org/packages/samchristy/piechart)! 22 | 23 | #### Example Usage #### 24 | ````php 25 | setTitle('Browser Usage Statistics (January - April)'); 32 | // Method chaining coming soon! 33 | $chart->addSlice('Google Chrome', 27, '#4A7EBB'); 34 | $chart->addSlice('Mozilla Firefox', 23, '#DA8137'); 35 | $chart->addSlice('Apple Safari', 11, '#9BBB59'); 36 | $chart->addSlice('Opera', 3, '#BE4B48'); 37 | $chart->addSlice('Other', 5, '#7D60A0'); 38 | 39 | $chart->draw(); 40 | $chart->outputPNG(); 41 | ```` 42 | #### Output #### 43 | ![Pie Chart](src/SamChristy/PieChart/example/example.png) 44 | 45 | *This example took 150ms to execute on my laptop (i3-350M @ 2.27 GHz). 46 | 47 | © Sam Christy 2013 48 | -------------------------------------------------------------------------------- /src/SamChristy/PieChart/documentation/namespace-SamChristy.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | Namespace SamChristy 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 |
