| /** |
| * 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 |
