  • Method Details

    • __fromPtr__

      public static Plot2d __fromPtr__(long addr)

    • setMinX

    • setPlotLineWidth

      public void setPlotLineWidth(int _plotLineWidth)

    • setNeedPlotLine

      public void setNeedPlotLine(boolean _needPlotLine)

    • setPlotGridColor

      public void setPlotGridColor(Scalar _plotGridColor)

    • setPlotTextColor

      public void setPlotTextColor(Scalar _plotTextColor)

    • setPlotSize

      public void setPlotSize(int _plotSizeWidth, int _plotSizeHeight)

    • setShowGrid

      public void setShowGrid(boolean needShowGrid)

    • setShowText

      public void setShowText(boolean needShowText)

    • setGridLinesNumber

      public void setGridLinesNumber(int gridLinesNumber)

    • setInvertOrientation

      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

      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
