Detailed Description

Defines a color gradient for use with e.g. QCPColorMap.

This class describes a color gradient which can be used to encode data with color. For example, QCPColorMap and QCPColorScale have setGradient methods which take an instance of this class. Colors are set with setColorStopAt(double position, const QColor &color) with a position from 0 to 1. In between these defined color positions, the color will be interpolated linearly either in RGB or HSV space, see setColorInterpolation.

Alternatively, load one of the preset color gradients shown in the image below, with loadPreset, or by directly specifying the preset in the constructor.

Apart from red, green and blue components, the gradient also interpolates the alpha values of the configured color stops. This allows to display some portions of the data range as transparent in the plot.

The QCPColorGradient(GradientPreset preset) constructor allows directly converting a GradientPreset to a QCPColorGradient. This means that you can directly pass GradientPreset to all the setGradient methods, e.g.:

qcpcolorgradient-setgradient

The total number of levels used in the gradient can be set with setLevelCount. Whether the color gradient shall be applied periodically (wrapping around) to data values that lie outside the data range specified on the plottable instance can be controlled with setPeriodic.

		const QCPRange &	range,
		QRgb *	scanLine,
		int	n,
		int	dataIndexFactor = 1,
		bool	logarithmic = false
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

This method is used to quickly convert a data array to colors. The colors will be output in the array scanLine. Both data and scanLine must have the length n when passed to this function. The data range that shall be used for mapping the data value to the gradient is passed in range. logarithmic indicates whether the data values shall be mapped to colors logarithmically.

if data actually contains 2D-data linearized via [row*columnCount + column], you can set dataIndexFactor to columnCount to convert a column instead of a row of the data array, in scanLine. scanLine will remain a regular (1D) array. This works because data is addressed data[i*dataIndexFactor].

Use the overloaded method to additionally provide alpha map data.

The QRgb values that are placed in scanLine have their r, g and b components premultiplied with alpha (see QImage::Format_ARGB32_Premultiplied).

	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Additionally to the other overload of colorize, this method takes the array alpha, which has the same size and structure as data and encodes the alpha information per data point.

The QRgb values that are placed in scanLine have their r, g and b components premultiplied with alpha (see QImage::Format_ARGB32_Premultiplied).

A more convenient way to create a custom gradient may be to clear all color stops with clearColorStops (or creating a new, empty QCPColorGradient) and then adding them one by one with setColorStopAt.

)

Sets whether data points that are outside the configured data range (e.g. QCPColorMap::setDataRange) are colored by periodically repeating the color gradient or whether they all have the same color, corresponding to the respective gradient boundary color.

As shown in the image above, gradients that have the same start and end color are especially suitable for a periodic gradient mapping, since they produce smooth color transitions throughout the color map. A preset that has this property is gpHues.

In practice, using periodic color gradients makes sense when the data corresponds to a periodic dimension, such as an angle or a phase. If this is not the case, the color encoding might become ambiguous, because multiple different data values are shown as the same color.
