Buffer Vertical Scale
Check Buffer Vertical Scale option to add an extra 10 measurements to the beginning and end
ranges of the vertical scale, making the plotted lines more centered in the graph.
Autoscale on Zoom
Check Autoscale on Zoom option to automatically scale the graph when zooming in using the
horizontal zoom tool only.
Synchronize Time
Check Synchronized Time option to view multiple graphs which only affects the composite graph
tab. When checked, multiple datasets will be shown over a scaled period of time through the
composite graph. When unchecked the multiple datasets will instead overlap each other and the time
shown is directly related to which graph the cursor has selected.
Synchronize Vertical Scale
Check Synchronize Vertical Scale option to view multiple graphs which only affects the composite
graph tab. When checked multiple datasets are shown with scaled vertical ranges, meaning each
parameter (temperature, humidity, etc.) will have one default set range for each parameter. When the
option is unchecked each plotted graph will have its own individual scaled vertical range.
Annotate Data
Check Annotate Data option to permit all annotations be viewed on the computer screen, this option
is beneficial when printing the annotations. When this option in unchecked, the data can still be
annotated, yet it is not visible on the screen unless that data point has been clicked, whereas the
annotation appears in the top left hand corner of the graph.

Check the Animate Graph option to create blinking maximum and minimum alarm setting lines on
the screen.
