Class ezcGraphDriverOptions

Class containing the basic driver options.

Most of the options of the driver class, like the width, height and font are set internally by the driver and not really relevant to the user of driver classes. You can configure how strings are automatically shortened, together with the postfix, which is appended to shortened strings, like the following example shows.

Configuration options, which special to the actual drivers are configured in the driver specific extensions of this option class.

  3.    $graph = new ezcGraphPieChart();
  4.    $graph->palette = new ezcGraphPaletteEzBlue();
  5.    $graph->title = 'Access statistics';
  7.    $graph->data['Access statistics'] = new ezcGraphArrayDataSet( array(
  8.        'Mozilla' => 19113,
