# 3.4 Timeline Zoomable Window

Figure 3.10: Initial display of the Timeline window of a 514 MB 16-process slog2 file with default preview resolution.

Most of the advanced features in the SLOG-2 viewer are provided through a zoomable window. Jumpshot-4 has two zoomable windows: Timeline and Histogram. Figure 3.10 is the initial display of the Timeline window of a half-gigabyte 16-timeline slog2 file. The zoomable window consists of several concealable and removable components. In the center of the window is the zoomable and scrollable canvas. For the Timeline window, the center canvas is called the timeline canvas. Directly on top of the zoomable canvas is the time display panel. On top of the display panel is the removable toolbar. To the left of the canvas is the concealable y-axis label panel. To the right of the canvas is the concealable row adjustment panel. At the bottom of the canvas is the time ruler canvas. Both the y-axis label and the row adjustment panels can be put out of sight by clicking the tabs in the dividers or dragging the dividers to the side of the window. The top toolbar can be dragged out of the window or be repositioned in the other three sides of the window. A bare-minimal zoomable window can be obtained by removing the toolbar and hiding the left and right panels. An almost-bare-minimal Timeline window looks like the one shown in Figure 2.1.
