C# Class Accord.Controls.Wavechart

Waveform chart control.

The Waveform chart control allows to display multiple waveforms at time.

Sample usage:

 // create data series array float[] testValues = new float[128]; // fill data series for ( int i = 0; i < 128; i++ ) { testValues[i] = Math.Sin( i / 18.0 * Math.PI ); } // add new waveform to the chart chart.AddWaveform( "Test", Color.DarkGreen, 3 ); // update the chart chart.UpdateWaveform( "Test", testValues );

Inheritance: System.Windows.Forms.Control

Public Methods

Method	Description
AddWaveform ( string name, Color color, int width ) : void	Add Waveform to the chart. Adds new empty waveform to the collection of waves. To update this wave the UpdateWaveform(string, float[]) method should be used.
AddWaveform ( string name, Color color, int width, bool updateYRange ) : void	Add Waveform to the chart. Adds new empty waveform to the collection of waves. To update this wave the UpdateWaveform(string, float[]) method should be used. Adds new empty data series to the collection of data series. The updateYRange parameter specifies if the waveform may affect displayable Y range. If the value is set to false, then displayable Y range is not updated, but used the range, which was specified by user (see RangeY property). In the case if the value is set to true, the displayable Y range is recalculated to fully fit the new data series.
RemoveAllWaveforms ( ) : void	Remove all waveforms from the chart.
RemoveWaveform ( string name ) : void	Remove a Waveform from the chart.
UpdateWaveform ( string name, float data ) : void	Update Waveform on the chart.
UpdateWaveform ( string name, float data, int samples ) : void	Update Waveform on the chart.
Wavechart ( ) : System	Initializes a new instance of the Wavechart class.

Protected Methods

Method Details

AddWaveform() public method

Add Waveform to the chart.

Adds new empty waveform to the collection of waves. To update this wave the UpdateWaveform(string, float[]) method should be used.

public AddWaveform ( string name, Color color, int width ) : void
name	string	Waveform name.
color	Color	Waveform color.
width	int	Waveform width.
return	void

AddWaveform() public method

Add Waveform to the chart.

Adds new empty waveform to the collection of waves. To update this wave the UpdateWaveform(string, float[]) method should be used.

Adds new empty data series to the collection of data series.

The updateYRange parameter specifies if the waveform may affect displayable Y range. If the value is set to false, then displayable Y range is not updated, but used the range, which was specified by user (see RangeY property). In the case if the value is set to true, the displayable Y range is recalculated to fully fit the new data series.

public AddWaveform ( string name, Color color, int width, bool updateYRange ) : void
name	string	Waveform name.
color	Color	Waveform color.
width	int	Waveform width.
updateYRange	bool	Specifies if should be updated.
return	void
