By default, the graph area and the data display area are automatically computed from the drawing area. However, the graph area or the data display area can be fixed by hand. If the graph area is fixed by hand, the data display area will be computed automatically from the fixed graph area. Similarly, if the data display area is fixed by hand, the graph area will be automatically computed from the fixed data display area.

Note: Be careful when you fix the data display area by hand. If the specified data display area is not small enough, the computed graph area can be larger than the drawing area and thus a part of the drawing of the chart may be not visible on the screen.

This can be done by means of the setGraphAreaRelatively or setDataDisplayAreaRelatively methods. In this case, the area that is fixed will be updated if the drawing area is modified (for example when the margins between the drawing area and the chart bounding box are changed).
