Method Detail

__fromPtr__

public static Plot2d __fromPtr__(long addr)

create

public static Plot2d create(Mat data)

Creates Plot2d object

Parameters:

data - \(1xN\) or \(Nx1\) matrix containing \(Y\) values of points to plot. \(X\) values will be equal to indexes of correspondind elements in data matrix.

Returns:

automatically generated

create

public static Plot2d create(Mat dataX,
                            Mat dataY)

Creates Plot2d object

Parameters:

dataX - \(1xN\) or \(Nx1\) matrix \(X\) values of points to plot.

dataY - \(1xN\) or \(Nx1\) matrix containing \(Y\) values of points to plot.

Returns:

automatically generated

render

public void render(Mat _plotResult)

setGridLinesNumber

public void setGridLinesNumber(int gridLinesNumber)

setInvertOrientation

public void setInvertOrientation(boolean _invertOrientation)

setMaxX

public void setMaxX(double _plotMaxX)

setMaxY

public void setMaxY(double _plotMaxY)

setMinX

public void setMinX(double _plotMinX)

setMinY

public void setMinY(double _plotMinY)

setNeedPlotLine

public void setNeedPlotLine(boolean _needPlotLine)

Switches data visualization mode

Parameters:

_needPlotLine - if true then neighbour plot points will be connected by lines. In other case data will be plotted as a set of standalone points.

setPlotAxisColor

public void setPlotAxisColor(Scalar _plotAxisColor)

setPlotBackgroundColor

public void setPlotBackgroundColor(Scalar _plotBackgroundColor)

setPlotGridColor

public void setPlotGridColor(Scalar _plotGridColor)

setPlotLineColor

public void setPlotLineColor(Scalar _plotLineColor)

setPlotLineWidth

public void setPlotLineWidth(int _plotLineWidth)

setPlotSize

public void setPlotSize(int _plotSizeWidth,
                        int _plotSizeHeight)

setPlotTextColor

public void setPlotTextColor(Scalar _plotTextColor)

setPointIdxToPrint

public void setPointIdxToPrint(int pointIdx)

Sets the index of a point which coordinates will be printed on the top left corner of the plot (if ShowText flag is true).

Parameters:

pointIdx - index of the required point in data array.

setShowGrid

public void setShowGrid(boolean needShowGrid)

setShowText

public void setShowText(boolean needShowText)

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Algorithm

Throws:

Throwable
