As discussed earlier, you can monitor system performance with either dial or graph displays. Use the Display setting of the Performance Meter Properties window to choose Dial or Graph displays. Remember to click SELECT on Apply to change the display in this session only, or click SELECT on Set Default to make the selected display your default every time you start the Performance Meter.
If you choose Graph, the Graph Type setting is activated on the Properties window. Choose Line to display a single line graph, and choose Solid to display a solid graph. Figure 9-9 shows a Performance Meter with a line graph on the left, and a solid graph on the right.
