Graphing a Data Channel
The next step is to graph data on the Datalink screen. We will begin by graphing a single channel, the
GPS_MPH.
To graph a single channel:
Place the mouse cursor over theGPS_MPH Channel
Button.
Left click the mouse button. TheGPS_MPH
Channel Button will now have a color box
displaying the color of the data graph that is now in
view in the main Graph window.
To insure the entire lap is displayed, select the User
Scale button
in the DataLink toolbar.
The data now in view represents the GPS_MPH as recorded for one lap. The numbers located at the
bottom of the graph represent time, from the start / finish line. When a data channel is graphed, all of
the values for the remaining data channels are now activated. To review the data:
Place the mouse cursor in the main Graph window and click the left mouse button.
With the mouse cursor in the main Graph window, click and hold the left mouse button and drag the
curser left and right. Observe the Channel Buttons while dragging the cursor. Data is updated real time,
relative to main Graph cursor location. The Left and Right arrow keys can also be used to move the
cursor in a similar manner.
To graph additional channels:
Place the mouse cursor over the GPS_LatG Channel
Button and click the left mouse button.
Add a third data channel by repeating the same
process for the GPS_Gs Channel Button.
To remove a data channel from the graph, simply left
click over that channel. To change the color of a
channel, continue to left click until a desirable color
is located.
