display waveformGraph from txt file data

[cm2009]

How to use the waveformGraph to display the moving chart based on the collected data (data from txt file)? How to incorporate the received / custom data (instead of random generated data)?

There is not only one way to display a data collection from a file. It also depends on your file structure.
But you can do something like that :

1) load the data at the application startup, for instance

_data = new ArrayList( 1000 );

using( StreamReader streamReader = new StreamReader( _fileName ) )
{
String line = streamReader.ReadLine();

while( line != null )
{
_data.Add( Convert.ToDouble( line ) );
line = streamReader.ReadLine();
}
}

_data.TrimToSize();

2) use a timer / thread to chart the data, for instance

_graph.PlotYAppend( _data[ _currentDataIndex ], _dataSize );
++_currentDataIndex;
if( _currentDataIndex >= _data.Count )
{
_currentDataIndex = 0;
}
