Changing Focus on GC Chart
Depending on how long your JRA recording is, the GC Chart can be quite cumbersome to view in full mode; therefore, you can refocus the chart. by dragging the handles on the slide bar to the section of the recording that you want to view. Once you have set the side on the slide bar, you can slide that section to the position of the chart that you are interested in studying.
The two ways to refocus on the GC Chart are described here:
To change focus on the Heap Usage chart
- Click and drag the handles on both sides on the GC Chart (Figure 9-2).
- Drag the GC Chart into the desired position (Figure 9-3).
To use the Move and Zoom buttons for the GC Chart
- Click the Move forward or Move backward buttons (marked 1 in Figure 9-4) to first decrease the GC Chart view.
- Click either of the Move buttons to slide the focus on the GC Chart.
- Click the Zoom in or Zoom out buttons (marked 2 in Figure 9-4) to decrease or increase the visible span of the GC Chart.
