/**
* Class for bar charts. Can make use of an unlimited amount of datasets and
* will display them as bars by default.
* X axis:
* - Labeled axis
* - Boxed axis label renderer
* Y axis:
* - Numeric axis
* - Exact axis label renderer
*
* <code>
* // Create a new line chart
* $chart = new ezcGraphBarChart();
*
* // Add data to line chart
* $chart->data['sample dataset'] = new ezcGraphArrayDataSet(
* array(
* '100' => 1.2,
* '200' => 43.2,
* '300' => -34.14,
* '350' => 65,
* '400' => 123,
* )
* );
*
* // Render chart with default 2d renderer and default SVG driver
* $chart->render( 500, 200, 'bar_chart.svg' );
* </code>
*
* Each chart consists of several chart elements which represents logical
* parts of the chart and can be formatted independently. The bar chart
* consists of:
* - title ( {@link ezcGraphChartElementText} )
* - legend ( {@link ezcGraphChartElementLegend} )
* - background ( {@link ezcGraphChartElementBackground} )
* - xAxis ( {@link ezcGraphChartElementLabeledAxis} )
* - yAxis ( {@link ezcGraphChartElementNumericAxis} )
*
* The type of the axis may be changed and all elements can be configured by
* accessing them as properties of the chart:
*
* <code>
* $chart->legend->position = ezcGraph::RIGHT;
* </code>
*
* The chart itself also offers several options to configure the appearance. As
* bar charts extend line charts the the extended configure options are
* available in {@link ezcGraphLineChartOptions} extending the
* {@link ezcGraphChartOptions}.
*
* @property ezcGraphLineChartOptions $options
* Chart options class
*
* @version //autogentag//
* @package Graph
* @mainclass
