Changing the Graphing Window (‘zooming’)
of the graphing window can be resized or zoomed in or out to
ved analysis. The zooming is done via mouse dragging of graph
onitors Tab. The number in the Max column equals 100% on the vertical scale.
To zoom in on the vertical scale, pull the top arrow towards the bottom arrow and vice-versa.
For example, when DriveWizard
™ is initially started, the vertical scale goes from –150% to
150%. To zoom in on the 0-100% area, pull the bottom arrow (

The vertical scale has a range from –150% to 150% of the maximum value of the parameter
being graphed. 100% of the value being graphed may be found by selecting the parameter being

with the zooming arrows, or the window can increase if the graph runs for greater than 60
seconds. The arrows may then be dragged apart to view the entire graphing time period.
Likewise, after graphing, the arrows (
