3.5.1 Summary States

Figure 3.23: State Summary Info Boxes of the Histogram window.

Since summary states are created through the statistics of real and preview states, summary states inherit properties of preview states, i.e. inclusion and exclusion ratios. Because of this, different representations of summary state are formed based on the PREVIEW_STATE_DISPLAY discussed earlier in section 2.2.1. Different representation of summary state can be selected through SUMMARY_STATE_DISPLAY pulldown menu located at the top of the left panel in the histogram window or through a similar variable defined in Preference window and in Table 3.20. Figure 3.22 is actually a CumulativeExclusionRatio view. Since the most time consuming timeline is the last one, we will zoom in the last three timelines and use them to discuss the visual representation of summary state. Figure 3.23 shows the last three timelines of Figure 3.22. Each summary state has a gray bordered box. Right mouse clicking at the bordered box pops up the Summary Info Box for the whole summary state. The info box lists the total number of real states it contains and detailed information of what state categories it contains. In the figure, the summary info boxes at timeline 15 and 13 show that the timeline 15 summary state contains about 148006 real states and the timeline 13 summary state has about 859613 real states, i.e. timeline 13 has 5.8 times the number of real states than that of timeline 15 within the same duration. Each summary state also displays the ratios of the total duration of each member state category to the duration of the canvas as colored boxes inside the gray bordered box. Right clicking at any of the colored boxes will display a summary info box that indicates the color and name of category and the corresponding ratio for the duration as the highlighted summary info box in the Figure 3.23.The remaining duration at the end of each timeline is unaccounted for. In this particular logfile, remaining time could be thought of being used for computation.

Figure 3.24: The OverlapInclusionRatio view of Figure 3.23.

Switching the SUMMARY_STATE_DISPLAY pulldown menu in histogram window in the figure to OverlapInclusionRatio redraws the histogram canvas. The histogram canvas now looks like one shown in Figure 3.24. Since the sum of all inclusion ratios is greater than 1.0, CumulativeInclusionRatio view is not provided in the histogram window3.9. All the member categories of the summary states in OverlapInclusionRatio view are drawn from the beginning of the histogram canvas and they are nested one inside others in decreasing inclusion ratio order, so the largest inclusion ratios are easily noticeable. In order to see the smallest ratios, one needs to zoom in around the beginning of the canvas. In Figure 3.24, the largest inclusion ratios in the 3 visible timelines are all royal blue and take up about the same amount of time. The 2nd largest ratios are all orange colored and is smallest in the timeline 15. Therefore OverlapInclusionRatio is good for comparison of member category contribution among different timelines.
