The signal data is accessed through the components properties. The signal name is shown on the top of the control and the field selected for processing is shown in the list box on the control. It can plot 1D or 2D data in various formats. The graph layout is controlled by setting the values of many of the control's properties. The Graph control is connected to a Signal control by calling one of the controls methods.
Output can be in real, imaginary or frequency, phase form.
Contour levels required are passed in an array to the routine. The Add NMO Event Application. Figure 3 shows an application that was assembled very quickly using the geophysical signal analysis components. The Signal control takes care of reading and writing the signal data to disk and holding the data in RAM for processing. The Graph control shows a view of the signal data.
