Detailed Description

Base class for chart layout computing.

Library: ilvcharts

This class is responsible for computing the layout of the chart. It computes the position of the following areas within the bounding box of the chart: the drawing area, the graph area, and the data display area. The drawing area is the maximum area where the drawing can be performed for a given chart. The graph area contains all the curves, scales, and labels of the chart. The data display area is the area where the data is displayed: no data points can be displayed outside of this area.

The following figure shows an example of these areas:

In this figure, the bounding box of the chart is the largest rectangle. The drawing area, graph area, and data display area are positioned within the bounding box. For this particular chart, the drawing area and the graph area are equivalent so they appear as the same rectangle (the second largest rectangle in the figure). You can see that the curves and scales are contained within this area. The smallest rectangle is the data display area containing all the data points of the chart.

By default, these three areas are automatically computed from the bounding box of the chart. The drawing area is computed by specifying a margin from the left, right, top, and bottom sides of the bounding box. The graph area and the data display area are then computed from the drawing area so that the graph area takes up the maximum amount of available space. However, the graph area or the data display area can be set by hand, thus allowing them to have a fixed position.

◆ setBottomMargin()

		IlBoolean	updateLayout = `IlFalse`
	)

Sets the bottom margin between the chart bounding box and the drawing area.

If the pointer to the associated chart is defined and updateLayout is equal to IlTrue, the layout is updated. This means that the different areas that must be updated are recomputed. Otherwise, if updateLayout is equal to IlFalse, the IlvChartLayout::invalidate method is simply called to specify that the layout must be updated. The layout will then be recomputed at the time of the drawing.

Parameters

m	The new bottom margin between the chart bounding box and the drawing area.
updateLayout	A Boolean indicating whether the layout must be updated immediately.

◆ setChartGraphic()

void IlvChartLayout::setChartGraphic ( IlvChartGraphic * chart )

chart The new chart graphic that is associated with the current object.

Note: This method should not be used directly by the user.

◆ setDataDisplayArea()

void IlvChartLayout::setDataDisplayArea	(	const IlvRect &	dataDisplayArea,
		IlBoolean	updateLayout = `IlFalse`
	)

Sets the data display area.

By default, the drawing area, the graph area, and the data display area are automatically computed from the bounding box of the chart. The drawing area is computed by specifying a margin from the left, right, top, and bottom sides of the bounding box. The graph area and the data display area are then computed from the drawing area so that the graph area takes up the maximum amount of available space. However, if you use this method to set the data display area by hand, the data display area is considered as fixed and will no longer be computed automatically.

If the pointer to the associated chart is defined and updateLayout is equal to IlTrue, the layout is updated. Only the graph area is recomputed since the data display area is fixed. The computation is performed from the data display area and does not take into account the drawing area.

Note: Be careful. If the specified data display area is not small enough, the computed graph area can be larger than the drawing area.

Otherwise, if updateLayout is equal to IlFalse, the IlvChartLayout::invalidate() method is simply called to specify that the layout must be updated. The layout will then be recomputed at the time of the drawing.

Parameters

dataDisplayArea	The new fixed area where the data for the associated chart are displayed.
updateLayout	Indicates whether the layout must be updated immediately.

Note: The specified data display area must be expressed in the same coordinate system as the bounding box of the associated chart.

◆ setDataDisplayAreaRelatively()

void IlvChartLayout::setDataDisplayAreaRelatively	(	IlvPos	leftMargin,
		IlvPos	rightMargin,
		IlvPos	topMargin,
		IlvPos	bottomMargin,
		IlBoolean	updateLayout = `IlFalse`
	)

Sets the data display area relative to the drawing area.

Sets the area where the data for the associated chart are displayed, by using margins relative to the drawing area. The left, right, top, and bottom margins between the drawing area and the data display area are set to leftMargin, rightMargin, topMargin and bottomMargin, respectively. By default, the drawing area, the graph area, and the data display area are automatically computed from the bounding box of the chart. The drawing area is computed by specifying a margin from the left, right, top, and bottom sides of the bounding box. The graph area and the data display area are then computed from the drawing area so that the graph area takes up the maximum amount of available space. However, if you use this method to set the data display area by hand, the data display area is considered as fixed and will no longer be computed automatically.

Note: If the drawing area is modified (for example, by changing the layout margins), the data display area will be updated since it is defined by using margins relative to the drawing area.

If the pointer to the associated chart is defined and updateLayout is equal to IlTrue, the layout is updated. Only the graph area is recomputed since the data display area is fixed. The computation is performed from the data display area.

Note: Be careful. If the specified data display area is not small enough, the computed graph area can be larger than the drawing area.

Otherwise, if updateLayout is equal to IlFalse, the IlvChartLayout::invalidate() method is simply called to specify that the layout must be updated. The layout will then be recomputed at the time of the drawing.

Parameters

leftMargin	The left margin between the drawing area and the data display area.
rightMargin	The right margin between the drawing area and the data display area.
topMargin	The top margin between the drawing area and the data display area.

The drawing area is computed by specifying a margin from the left, right, top, and bottom sides of the bounding box. The graph area and the data display area are then computed from the drawing area so that the graph area takes up the maximum amount of available space. However, if you use this method to set the graph area by hand, the graph area is considered as fixed and will no longer be computed automatically.
