Plot the spatial frequency magnitude spectrum along a line in the sensor window
plotSensorFFT([ori = 'h'], [dataType = 'volts'], [figNum = GRAPHWIN])
Purpose:
The magnitude spectrum of the sensor data along a line ('h' or 'v')
can be computed as abs(fft(voltageData)). These are plotted in a
graph window.
The data are extracted from the selected ISA.
This routine is normally applied to Monochrome sensor data.
We apply the routine to color data by interpolating the data in the color
channels and then computing the separate FFT images.
Example:
plotSensorFFT('h', 'volts')
