Trend Plot Adjust Scroll Bars
Use the scroll bars on the horizontal and vertical axes to move the trend
plot and adjust its resolution.
Move
The Trend Plot screen includes two Move scroll bars: one on the
horizontal axis and one on the vertical axis.
• Use the Move scroll bar on the horizontal axis to move the trend plot
window. The Left arrow moves the window backward in time. The
Right arrow moves the window forward in time.
• Use the Move scroll bar on the vertical axis to move the trend plot
through the range of input, in engineering units. The Up arrow shifts
the data up. The Down arrow shifts the data down.
Res (resolution)
The Trend Plot screen includes two Res (resolution) scroll bars: one on
the horizontal axis and one on the vertical axis.
• Use the Res scroll bar on the horizontal axis to adjust the time frame
displayed in the trend plot. The Left (-) arrow zooms out to show a
longer length of time on the trend plot. The Right (+) arrow zooms in
to show a shorter amount of time on the plot, thereby providing
greater detail.
• Use the Res scroll bar on the vertical axis to increase or decrease the
resolution of the trend plot. The Up (+) arrow increases the resolution
of the plot and decreases the width of the plot’s scale. The Down (-)
arrow decreases the resolution of the plot and increases the width of
the plot’s scale.
