Timeline Tab
The timeline tab shows a chart of counts of events (Range Axis) on a time period (Domain Axis). The counts of events are also separated by event type, which are differentiated by color of the corresponding bar. The time period of accumulation by default is one day, from 0h00 to 23h59m59s.999. But this can be changed right clicking on the domain axis labels panel, which is highlighted on mouse over event, and selecting the appropriate period of accumulation from the popup menu that is presented. Also the timezone for accumulation can be changed in this same popup menu. Depending on the time period of accumulation chosed, the visible range on the chart can be altered. If this occurs a dialog will be shown alerting the user and asking if he wants to continue. The modification can occur if the bar width of the selected new time period will become to great to show, or too small, on the current visible range.
The ResultSet can be splitted in 2 or more charts, by Bookmark or by Category. To do so, select the bookmarks (or categories), and right click on the Range Axis panel, which is highlighted on mouse over, and select "Split by bookmark" (or by category). The selected items will be used to split the datasets between the charts. Data on more than one selected bookmarks or categories will be counted on each respective chart. If the split is not configured, the selected bookmarks or categories will be used to filter the resultset.
The mouse in conjunction with some keys can be used to navigate on the chart. To zoom in, you can click and drag to draw a rectangle on the chart plot area. The range value corresponding to the height of the rectangle will be the top most value of the plot area after the zoom. And the dates corresponding to the first and end edge of the rectangle will be the first and last dates of the new visible range of the plot area. You can also use the mouse wheel to zoom in. Move forward and the chart will zoom in, move backward and the chart will zoom out. To zoom only on the domain axis press the SHIFT key and move the wheel while the key is pressed. To zoom only in range axis, use the CTRL key. The range axis is anchored in the 0 value, as the counting of event will never be negative. To pan the visible area left and right, press the CTRL key and click and drag the mouse on the plot visible area while the key is pressed.
The legend shows the different event types and the corresponding colors randomly chosen to represent them. The user can select event types and, right clicking on the legend to show a popup menu, show or hide the corresponding bars on the current visible chart. The names of hidden event types will be shown with a strike through font.
With the SHIFT key pressed, the user can click on a point of chart and right drag the mouse in the plot area to draw a blue rectangle that will represent an interval of dates. If you click on the plot area of the chart, a popup menu will be presented with the options to create filter intervals that correspond to dates before or after the corresponding date of the clicked point. Also, right clicking on the plot area will show a popup menu with the "Open interval definition dialog". In this dialog, the user can create and edit the filter ranges textually. With the intervals defined, they can be used as parameters to some chart operations. To highlight all the items on the interval, click on the interval, and select the popup menu option "Select items on this interval". To filter the result set visible on the table pan, choose "Filter defined intervals". The tab of the timeline chart will become Red to indicate to the user that the current defined filters shown on the chart are being user to filter the result set presented on the remainder tabs. To remove the filter, the user can click on the down arrow button on the left top of the chart panel a choose the option "Apply filters". This option does not remove the defined intervals that can be used again for other operations. To delete a defined interval, click on it an select "Delete interval" or click on "Clear defined intervals" on the top left chart panel button popup menu to delete all defined intervals.
