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 />
