When viewing a limit trend on a touch screen, drag is used for panning and
scrolling. For example, to drag the scroll box on the y-axis or to drag the
time slider to a different time period. Note that dragging on a standard trend
is used to select a zoom region.
When viewing a limit trend on a touch screen, you can pinch in or out to
zoom. Note that when you use a mouse scroll wheel, the limit trend will
zoom in both x and y axes simultaneously around the cursor point.
When viewing a limit trend on a touch screen, you can tap and hold where
you would normally use a mouse to right-click. For example, to call up a
shortcut menu.
Changing the scale on a trend
When viewing a standard trend, you can change the scale that is used for the trend. For
example, you can switch from having a single scale for all plots to individual scales, in
engineering units, for each plot. The figure below shows the scale options available in a list
which you can access from the trend toolbar.
Tip:
For information about how to change the scale on a limit trend, see “Limit trend
controls.”
