README
A reasonably efficient* class for drawing pie charts with ImageMagick or GD in PHP. Intended as a
learning exercise for using the NetBeans IDE and the Xdebug profiler and debugger. The code is
available under the GNU GPL v3.0, so feel free to use it
with attribution. I recommend using the Imagick version, PieChartImagick
over the GD version,
PieChartGD
.
Demonstration
Below is the code required to generate a pie chart and echo it to the client's browser. The example
uses the method outputPNG()
to tell the browser to render the image. Alternatively, the function
forceDownloadPNG()
can be used to instruct the browser to bring up the save dialog.
