Status Boxes:
The mouse can be positioned on a graph and the status box will show the information for
that spot on the graph. The data shown in the status box will be the actual time and date
the data at that point was taken, and the level and temperature at that point. The mouse
must be on the graph to update the status information. If a graph is not displayed, the
status box for that graph will indicate it is inactive.
Zoom In:
This button will only work if both graphs are displayed. This will move the cursors closer
together and redisplay the data between the cursors on the auxiliary graph. This allows
viewing sections of the data with greater detail.
Zoom Out:
This button will only work if both graphs are displayed. When selected, it will move the
cursors farther apart and redisplay the data between the cursors on the auxiliary graph.
Pan Left:
This button will only work if both graphs are displayed. Both cursors will move an equal
distance to the left.
Pan Right:
This button will only work if both graphs are displayed. Both cursors will move an equal
distance to the right.
Main Graph:
This button will display only the main graph in a larger area. The status box for the main
graph is still active, but the auxiliary graph status box is not.
Both Graphs:
This button will display both the main graph and the auxiliary graph on the same screen.
In this mode the main graph will also have the cursors displayed. The Auxiliary graph
will show all the data between the cursors. Both the main graph and the auxiliary graph
status boxes will function in this mode.
Aux Graph:
This button will display only the auxiliary graph and in a larger area. The status box for
the auxiliary graph is active, but the main graph status box is not.
Options:
This button allows options for you to modify and print the auxiliary graph.
Quit:
This button will cause the “View Graph” screen to close and redisplay the main screen.
