Choosing the Representation<br />

Figure 20. The Options menu in a visualzer.<br />

Choose Representation from the Options menu to display another menu that<br />

gives the choices for how the values are represented in the display window. The<br />

choices are described below. You can control aspects of how these visualizers<br />

appear by changing their parameters, as described later in this section.<br />

* Choose Text to display the values as numbers or letters. This is the default.<br />

* Choose Dither to display the values as a shading from black to white.<br />

Groups of values in a low range are assigned more black pixels; groups<br />

of values in a high range are assigned more white pixels. This has the<br />

effect of displaying the data in various shades of gray. Figure 21 shows a<br />

2-dimensional dither visualizer. The lighter area indicates values that are<br />

higher than values in the surrounding areas; the darker area indicates values<br />

that are lower than surrounding values.<br />

For complex numbers, <strong>Prism</strong> uses the modulus.<br />
