When viewing data within a graph, the user may zoom in and out to better view the information. This
button resets the viewing pane back to the default zoom. Zooming is controlled through pinch and zoom
functionality.
2. Show Annunciations
This button is used to toggle whether annunciation conditions are displayed in historical graphs displays.
It is only enabled as long as the data is being displayed in graph view. When this button is clicked, verti-
cal lines will be added to the display, which correspond to any annunciations that have been triggered
during the time period represented on the graph. After the button has been clicked, the text will change
to

the text back to Show Annunciations .
