Enclosing class:

IlvChart
```
public class IlvChart.Area
extends JComponent
```
The component where the graphical representation of charts and scales are displayed. The chart area component is not designed to be instantiated. It is automatically created by the chart and can be accessed by the IlvChart.getChartArea() method. This component is the place where all the drawing operations are performed (the graphical representations of the data themselves, and the decorations). This container also contains the Scales components. We can distinguish two areas within the chart area component:
- the drawing rectangle, where drawings are performed (both charts and scales). All the drawings occurring in the chart area are clipped by this rectangle. The drawing rectangle is equal to the component bounds minus its insets and can be retrieved by the getDrawRect() method.
- the plotting rectangle, the region where data is projected and displayed. The bounds of this rectangle are computed according to the drawing rectangle and the chart area internal margins. It can be retrieved by means of the getPlotRect() method.
The following figure shows the different parts of the chart area:
