      • setShowGrid

        public void setShowGrid​(boolean needShowGrid)

      • setShowText

        public void setShowText​(boolean needShowText)

        public void setInvertOrientation​(boolean _invertOrientation)

      • 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.

      • render

        public void render​(Mat _plotResult)

      • 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
