WaveRIDER 73
To move an X-cursor:
1) Select the Value Data Tab.
2) Position the mouse pointer over the X-cursor grip (the small triangle below a X-
cursor) then press and hold the left mouse button and drag it left or right
releasing the mouse button when the X-cursor is at the desired location.
The user can also press the [tab] key to toggle select an X-cursor. When the
desired X-cursor is selected, the small triangle will turn red. Then pressing either
the left or right arrow keys will step the X-cursors. Each step is one pixel or one
degree which ever is larger. This feature achieves cursor positions that are more
precise.
Moving the selected cursor can be pushed into other cursors causing them to
move them ahead of it.
The position of an X-cursor controls the values displayed in the Data Table. When an X-
cursor is moved, values in the Data Table are automatically updated.
The Data Table includes a row for each of the sensors on the WaveRIDER. The
numbers in the four columns indicate the Y-values at the intersection of a Data Plot with
an X-cursor. (Refer to section 4.4.9 Data Tabs)
When an X-cursor is dragged to a new position, it automatically snaps to the closest
real X-value. Notice on highly magnified graphs that the cursor jumps from point to
point. In an extreme case, if the graph is so highly magnified that there are no real X-
values to move to, the X-cursors cannot be moved at all.
The Process Origin is the initial point from which all X-axis position data is
calculated. After releasing the Process Origin at the appropriate point on the
graph, X-cursor values are recalculated and displayed.
