Setting General Properties of a Chart Layout Object
The following properties are defined for a layout object:
Property | Methods | Default Value |
|---|---|---|
Areas Computation Properties | ||
Graph and Data Display Areas Automatically Computed | isAutoLayout setAutoLayout | IlvTrue |
Graph Area Automatically Computed | isAutoGraphArea setAutoGraphArea | IlvTrue |
Data Display Area Automatically Computed | isAutoDataDisplayArea setAutoDataDisplayArea | IlvTrue |
Areas Positioning Properties | ||
Drawing Area Defined by: Margins Between the Chart Bounding Box and the Drawing Area | getLeftMargin setLeftMargin getRightMargin setRightMargin getTopMargin setTopMargin getBottomMargin setBottomMargin | 0 0 0 0 |
Graph Area Defined by Hand Using: Margins Between the Drawing Area and the Graph Area A Rectangle Corresponding to the Graph Area | getGraphAreaRelatively setGraphAreaRelatively getGraphArea setGraphArea | |
Data Display Area Defined by Hand Using: Margins Between the Drawing Area and the Data Display Area A Rectangle Corresponding to the Data Display Area | getDataDisplayAreaRelatively setDataDisplayAreaRelatively getDataDisplayArea setDataDisplayArea | |
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. |
You can fix the graph area or the data display area by hand in two ways:
By specifying margins relative to the drawing area 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).
By setting the rectangle corresponding to the area to be fixed directly This can be done by means of the setGraphArea or setDataDisplayArea methods. In this case, the area that is fixed does not depend on the drawing area and is not updated when the drawing area is modified.
