Zoom Controls

Time based graphs in RGP provide Zoom controls for adjusting the time scale that is viewable on screen. The following set of zoom icons are displayed above each graph that supports zooming:

ZoomSelectionRef Zoom to selection

When Zoom to selection is clicked, the zoom level is increased to a selected region or selected event. A selection region is set by holding down the left mouse button while the mouse is on the graph and dragging the mouse either left or right. A colored overlay will highlight the selected region on the graph. For graphs that support it, an event may be selected by clicking on it with the mouse (either the left or right button). Zoom to selection can also be activated by right clicking on a selection on the graph and choosing the Zoom to selection context menu option. Zooming to a selected event can be accomplished by simply double clicking the event. Pressing the Z shortcut key while holding down the CTRL key activates Zoom to selection as well.

ZoomResetRef Zoom reset

When Zoom reset is clicked, the zoom level is returned to the original level to reveal the entire time span on the graph. The zoom level can also be reset using the H shortcut key.

ZoomInRef Zoom in

Increases the zoom level incrementally to display a shorter time span on the graph. The zoom level is increased each time this icon is clicked until the maximum zoom level is reached. Alternatively, holding down the CTRL key and scrolling the mouse wheel up while the mouse pointer is over the graph will also zoom in for a more detailed view. Zooming in can be activated with the A shortcut key. To zoom in quickly at a 10x rate, press the S shortcut key.

ZoomOutRef Zoom out

Decreases the zoom level incrementally to display a longer time span on the graph. The zoom level is decreased each time this icon is clicked until the minimum zoom level is reached (i.e. the full available time region). Alternatively, holding down the CTRL key and scrolling the mouse wheel down while the mouse pointer is over the graph will also zoom out for more detailed view. Zooming out can be activated with the Z shortcut key. To zoom out quickly at a 10x rate, press the X shortcut key.

Zoom Panning

When zoomed in on a graph region, the view can be shifted left or right by using the horizontal scroll bar. The view can also be scrolled by dragging the mouse left or right while holding down the spacebar and the left mouse button. Left and right arrow keys can be used to scroll as well.

Synchronized Zoom

Normally, adjusting the view of a time based graph (by zooming in and scrolling) doesn’t affect graphs on other panes. This can be useful in some cases when tracking more than one item. However, it is sometimes useful to lock both the event timing and wavefront occupancy views to the same visible time window. There is an option to control this in the ‘General’ tab of the Settings section called Sync event time windows. With this enabled, any zooming and scrolling in one window will be reflected in the other. If adjustments are made in the wavefront occupancy view, the vertical scroll bar in the event timing view will be automatically adjusted so that there are always events shown on screen if an event isn’t manually selected.
