80 | * The view is composed of two histograms and two controls: |
81 | * <ul> | |
faa38350 | 82 | * <li>an event distribution histogram for the whole trace; |
c392540b FC |
83 | * <li>an event distribution histogram for current time window (window span); |
84 | * <li>the timestamp of the currently selected event; | |
85 | * <li>the window span (size of the time window of the smaller histogram). | |
86 | * </ul> | |
87 | * The histograms x-axis show their respective time range. | |
