  #include <Wt/Chart/WAbstractChart>
  Abstract base class for MVC-based charts.
  This is an abstract class and should not be used directly.
  As an abstract base for MVC-based charts, this class manages the model setModel() and provides virtual methods that listen to model changes. In addition, it gives access to generic chart properties such as the title setTitle() and title font setTitleFont(), the chart palette setPalette(), plot area padding setPlotAreaPadding(), and the background fill color setBackground().
  Styling through CSS is not applicable.
  Returns the background of the chart.
  Returns whether chart layout is computed automatically.
  Returns the model.
  If a model was set using setModel(WAbstractItemModel *), then this model will be returned by this call.
  Returns the model.
  Paint the chart in a rectangle of the given painter.
  Paints the chart inside the painter, in the area indicated by rectangle. When rectangle is a null rectangle, the entire painter window is used.
  Implemented in Wt::Chart::WCartesianChart, and Wt::Chart::WPieChart.
  Returns the palette for the chart.
  Returns the internal margin for the main plot area.
  This is either the paddings set through setPlotAreaPadding() or computed using setAutoLayoutEnabled()
  Configures the chart layout to be automatic.
  This configures the plot area so that the space around it is suited for the text that is rendered (axis labels and text, the title, and legend).
  The default value is
  false, and the chart layout is set manually using values set in setPlotAreaPadding().
  Sets a background for the chart.
  Set the background color for the main plot area.
  The default is a completely transparent background.
  Sets the model.
  The model is used by the chart to get its data. Ownership of the model is not transferred, and if a previous model was set it is not deleted.
  The default model is a
  0 model.
  This creates an internal proxy model that presents the WAbstractItemModel as a WAbstractChartModel. Use setModel(WAbstractChartModel *) directly for highest performance (avoiding the overhead of boost::any for numeric data).
  Set an internal margin for the main plot area.
  This configures the area (in pixels) around the plot area that is available for axes, labels, and titles.
  The default is dependent on the chart type.
  Alternatively, you can configure the chart layout to be computed automatically using setAutoLayoutEnabled().
  Set a chart title.
  The title is displayed on top of the chart, using the titleFont().
  The default title is an empty title ("").
  Set the font for the chart title.
  Changes the font for the chart title.
  The default title font is a 15 point Sans Serif font.
  Returns the font for the chart title.
