Navigation Data Screens
5.4.2 Graph View
Graph view screens include a parameter description and a data graph parameter value activity.
The units of the data value, the lock icon, and the scroll arrows are similar as for text view. The
short parameter name is shown, but pressing Y opens a pop-up to reveal the complete name. Due
to the height of the data graphs, only two parameters are displayed at a time and only one
parameter can be locked. A parameter moves to the top of the data list when it is locked. If more
than on parameter was locked when graph view is selected, the top parameter in the list remains
locked and the others return to their original positions in the data list.

Figure 5-9 Sample graph view screen
The <strong>MICROSCAN</strong> constructs the graphs from left to right across the screen and generates a point
on the graph for each data stream transmission from the ECM. How quickly the graph area of the
screen is filled depends upon the transmission speed of the ECM, so expect graphing speed
differences between makes and models. The screen is wide enough to display 64 data points on
a graph. Once the graph fills the screen older point at the left edge are hidden as new points on
the right edge are added. The value of the current sample point displays below the parameter
name alongside the graph.
A special cursor function that allows you to scroll across the data graphs is available on the exit
menu in graph view. When selected a cursor appears as a vertical line on the graphs, arrows on
either side of the graph show the scrolling direction has changed, and a frame counter the show
the relative position of the cursor displays in the title bar. The sampled value at the point of the
cursor displays below the parameter description.
