Methods

Create(InputArray)

Creates a Plot2d object.

public static Plot2d Create(InputArray data)

Parameters

data InputArray

1xN or Nx1 matrix containing Y values of points to plot. X values will be equal to indexes of corresponding elements in data matrix.

Returns

Plot2d

Create(InputArray, InputArray)

Creates a Plot2d object.

public static Plot2d Create(InputArray dataX, InputArray dataY)

Parameters

dataX InputArray

1xN or Nx1 matrix X values of points to plot.

dataY InputArray

1xN or Nx1 matrix containing Y values of points to plot.

Returns

Plot2d

Render(OutputArray)

Renders the plot to an image.

public virtual void Render(OutputArray plotResult)

Parameters

plotResult OutputArray

SetGridLinesNumber(int)

Sets the number of grid lines.

public virtual void SetGridLinesNumber(int gridLinesNumber)

Parameters

gridLinesNumber int

SetInvertOrientation(bool)

Sets whether to invert the orientation of the plot.

public virtual void SetInvertOrientation(bool invertOrientation)

Parameters

invertOrientation bool

SetMaxX(double)

Sets the maximum X value of the plot.

public virtual void SetMaxX(double plotMaxX)

Parameters

plotMaxX double

SetMaxY(double)

Sets the maximum Y value of the plot.
