*
* For additional options configuring the apperance of the chart you may also
* want to check the option classes to configure the respective renderer you
* are using:
*
* - ezcGraphRendererOptions
* - ezcGraphRenderer2dOptions
* - ezcGraphRenderer3dOptions
*
* <code>
* $graph = new ezcGraphLineChart();
* $graph->title = 'Wikipedia articles';

* $graph->options->fillLines = 220;
* $graph->options->lineThickness = 3;
*
* // Add data
* foreach ( $wikidata as $language => $data )

* $graph->data[$language] = new ezcGraphArrayDataSet( $data );
* }
*
* $graph->render( 400, 150, 'tutorial_line_chart.svg' );
* </code>
*
* @property float $lineThickness
* Thickness of chart lines
* @property mixed $fillLines
* Status wheather the space between line and axis should get filled.
* - FALSE to not fill the space at all.
* - (int) Opacity used to fill up the space with the lines color.
* @property int $symbolSize
* Size of symbols in line chart.
* @property ezcGraphFontOptions $highlightFont
* Font configuration for highlight tests
* @property int $highlightSize
* Size of highlight blocks
* @property bool $highlightLines
* If true, it adds lines to highlight the values position on the
* axis.
* @property true $stackBars
* Stack bars
