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 );

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
