b544077e | 57 | * Re-usable histogram widget. |
20ff3b75 | 58 | * |
b544077e | 59 | * It has the following features: |
c392540b FC |
60 | * <ul> |
61 | * <li>Y-axis labels displaying min/max count values | |
62 | * <li>X-axis labels displaying time range | |
63 | * <li>a histogram displaying the distribution of values over time (note that | |
64 | * the histogram might not necessarily fill the whole canvas) | |
65 | * </ul> | |
66 | * The widget also has 2 'markers' to identify: | |
67 | * <ul> | |
68 | * <li>a red dashed line over the bar that contains the currently selected event | |
69 | * <li>a dark red dashed line that delimits the right end of the histogram (if | |
70 | * it doesn't fill the canvas) | |
71 | * </ul> | |
72 | * Clicking on the histogram will select the current event at the mouse | |
73 | * location. | |
74 | * <p> | |
75 | * Once the histogram is selected, there is some limited keyboard support: | |
76 | * <ul> | |
77 | * <li>Home: go to the first histogram bar | |
78 | * <li>End: go to the last histogram bar | |
79 | * <li>Left: go to the previous histogram | |
80 | * <li>Right: go to the next histogram bar | |
81 | * </ul> | |
82 | * Finally, when the mouse hovers over the histogram, a tool tip showing the | |
83 | * following information about the corresponding histogram bar time range: | |
84 | * <ul> | |
85 | * <li>start of the time range | |
86 | * <li>end of the time range | |
87 | * <li>number of events in that time range | |
88 | * </ul> | |
