PHP Pie Chart, Line Chart & Bar Chart

Line, bar and pie charts are the most commonly used charts. By default, all charts plotted are line charts when no renderer plugin is specified.

For bar charts, simply use plugin::BarRenderer,

1	$pc->set_series_default(array('renderer'=> 'plugin::BarRenderer', 'rendererOptions'=> array('barPadding'=>6,'barMargin'=>40)));

For pie charts, use plugin::PieRenderer when specify renderer property.

1	$pc->set_series_default(array('renderer'=> 'plugin::PieRenderer', 'rendererOptions'=> array('sliceMargin'=>8)));
