Detailed Description

Holds the two-dimensional data of a QCPColorMap plottable.

This class is a data storage for QCPColorMap. It holds a two-dimensional array, which QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a color, depending on the value.

The size of the array can be controlled via setSize (or setKeySize, setValueSize). Which plot coordinates these cells correspond to can be configured with setRange (or setKeyRange, setValueRange).

The data cells can be accessed in two ways: They can be directly addressed by an integer index with setCell. This is the fastest method. Alternatively, they can be addressed by their plot coordinate with setData. plot coordinate to cell index transformations and vice versa are provided by the functions coordToCell and cellToCoord.

A QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if allocated) has the same size as the data map. It can be accessed via setAlpha, fillAlpha and clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on the first call of setAlpha. clearAlpha restores full opacity and frees the alpha map.

This class also buffers the minimum and maximum values that are in the data set, to provide QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value that is greater than the current maximum increases this maximum to the new value. However, setting the cell that currently holds the maximum value to a smaller value doesn't decrease the maximum again, because finding the true new maximum would require going through the entire data array, which might be time consuming. The same holds for the data minimum. This functionality is given by recalculateDataBounds, such that you can decide when it is sensible to find the true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience parameter recalculateDataBounds which may be set to true to automatically call recalculateDataBounds internally.

◆ alpha()

unsigned char QCPColorMapData::alpha	(	int	keyIndex,
		int	valueIndex
	)

Returns the alpha map value of the cell with the indices keyIndex and valueIndex.

If this color map data doesn't have an alpha map (because setAlpha was never called after creation or after a call to clearAlpha), returns 255, which corresponds to full opacity.

◆ cellToCoord() [1/2]

void QCPColorMapData::cellToCoord	(	int	keyIndex,
		int	valueIndex,
		double *	key,
		double *	value
	)		const

Transforms cell indices given by keyIndex and valueIndex to cell indices of this QCPColorMapData instance. The resulting coordinates are returned via the output parameters key and value.

If you are only interested in a key or value coordinate, you may pass 0 as key or value.

Note: The QCPColorMap always displays the data at equal key/value intervals, even if the key or value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes, you shouldn't use the QCPColorMapData::cellToCoord method as it uses a linear transformation to determine the cell index.

◆ coordToCell() [1/2]

Transforms plot coordinates given by key and value to cell indices of this QCPColorMapData instance. The resulting cell indices are returned via the output parameters keyIndex and valueIndex.

The retrieved key/value cell indices can then be used for example with setCell.

If you are only interested in a key or value index, you may pass 0 as valueIndex or keyIndex.

Note: The QCPColorMap always displays the data at equal key/value intervals, even if the key or value axis is set to a logarithmic scaling.

◆ recalculateDataBounds() [1/2]

void QCPColorMapData::recalculateDataBounds ( )

Goes through the data and updates the buffered minimum and maximum data values.

Calling this method is only advised if you are about to call QCPColorMap::rescaleDataRange and can not guarantee that the cells holding the maximum or minimum data haven't been overwritten with a smaller or larger value respectively, since the buffered maximum/minimum values have been updated the last time. Why this is the case is explained in the class description (QCPColorMapData).

Note that the method QCPColorMap::rescaleDataRange provides a parameter recalculateDataBounds for convenience. Setting this to true will call this method for you, before doing the rescale.

◆ setAlpha()

void QCPColorMapData::setAlpha	(	int	keyIndex,
		int	valueIndex,
		unsigned char	alpha
	)

Sets the alpha of the color map cell given by keyIndex and valueIndex to alpha. A value of 0 for alpha results in a fully transparent cell, and a value of 255 results in a fully opaque cell.

If an alpha map doesn't exist yet for this color map data, it will be created here. If you wish to restore full opacity and free any allocated memory of the alpha map, call clearAlpha.

Note that the cell-wise alpha which can be configured here is independent of any alpha configured in the color map's gradient (QCPColorGradient). If a cell is affected both by the cell-wise and gradient alpha, the alpha values will be blended accordingly during rendering of the color map.

◆ setCell() [1/2]

void QCPColorMapData::setCell	(	int	keyIndex,
		int	valueIndex,
		double	z
	)

Sets the data of the cell with indices keyIndex and valueIndex to z. The indices enumerate the cells starting from zero, up to the map's size-1 in the respective dimension (see setSize).

In the standard plot configuration (horizontal key axis and vertical value axis, both not range-reversed), the cell with indices (0, 0) is in the bottom left corner and the cell with indices (keySize-1, valueSize-1) is in the top right corner of the color map.

void QCPColorMapData::setData	(	double	key,
		double	value,

	)

Sets the data of the cell, which lies at the plot coordinates given by key and value, to z.

Note: The QCPColorMap always displays the data at equal key/value intervals, even if the key or value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes, you shouldn't use the QCPColorMapData::setData method as it uses a linear transformation to determine the cell index. Rather directly access the cell index with QCPColorMapData::setCell.
