Background
Visualizers are plug-ins you can write that permit the author access to the acquired data for additional
processing. These plugs ins reside in a directory off the main installed directory called “Visualizers”.
When you add a visualizer DLL to that directory, the Visualizer will shows up in the Visualizer menu
menu list as shown below.
There is a DotNet interface embedded in the QA 401 executable that appears as below:
namespace QA400NS
{
public interface IVisualizer
{
string GetMenuName();
void Start( Form parent);
bool ShowData( VisSettings settings, double [] dataOutL, double [] dataInL, double []
dataOutR, double [] dataInR);
}
public class VisSettings
{
public double SampleFreq;
public double Gen1Freq;
}
}
The visualizer writer must implement three functions:
GetMenuName() is the name of the interface that appears on the visualizer menu drop down.
Start() is called when the interface is first loaded. This allows the visualizer to do whatever it needs to
get setup. Usually, this will include creating a dialog box and positioning it as needed.
