Plotting Snapshot Graph

This test selects several necessary items from the data
list to plot graphs and makes data comparison on a long
term basis. It is an effective test particularly in emission
related evaluations.
For trouble diagnosis, you can collect graphic data (snap
shot) directly from the vehicle. You can replay the
snapshot data as needed. There fore, accurate diagnosis
is possible, even though the vehicle is not available.
