The Timeline view has several controls that you use to control how the timeline is displayed. Some of these controls also influence the presentation of data in the Details and Analysis views.
The width of the vertical ruler can be adjusted by placing the mouse pointer over the right edge of the ruler. When the double arrow pointer appears, click and hold the left mouse button while dragging. The vertical ruler width is saved with your session.
The Kernel and Stream timeline rows can be reordered. You may want to reorder these rows to aid in visualizing related kernels and streams, or to move unimportant kernels and streams to the bottom of the timeline. To reorder a row, left click on the row label. When the double arrow pointer appears, drag up or down to position the row. The timeline ordering is saved with your session.
Memcpy and Kernel rows can be filtered to exclude their activities from presentation in the Details, Detail Graphs and Analysis views. To filter out a row, left click on the filter icon just to the left of the row label. When a row is filtered, any intervals on that row are dimmed to indicate their filtered status.
Intervals associated with collapsed rows are not shown in the Details, Detail Graphs and Analysis views. For example, if you collapse a device row, then all memcpys, memsets, and kernels associated with that device are excluded from the results shown in those views.
There are two modes for timeline coloring. The coloring mode can be selected in the View menu, in the timeline context menu (accessed by right clicking in the timeline view), and on the Visual Profiler toolbar. In kernel coloring mode, each type of kernel is assigned a unique color (that is, all activity intervals in a kernel row have the same color). In stream coloring mode, each stream is assigned a unique color (that is, all memcpy and kernel activity occurring on a stream are assigned the same color).
