Options
Zoom Graph Out Allows more of a chart(s) to be seen by decreasing the dimensions.
Zoom Graph In Zooms in on a chart(s), providing more detail to a smaller area of the chart(s).
Maximize Graph Causes PostView to display one chart only. For example, if you were viewing 3 charts and
wanted to get a better view of Chart 2, you could use Maximize Graph so it would be
displayed using the full chart viewing area, as compared to using one third of the area.
The Maximize Graph feature can also be invoked by double-clicking in the chart region
of the chart you want to maximize.
Once you have maximized a chart, the pull-down menu option is replaced by a Restore
option. Selecting Restore from the menu returns the main window to its previous
multiple-chart viewing status. The restore feature can also be invoked by
double-clicking [or right-clicking] and selecting Restore graph from the pop-up menu.
Absolute time
(Ctrl+A) PostView normally displays timestamp information in a relative format; +/- time from the
trigger point, see note. If the instrument and acquisition software that created the data
file supported timestamp logging, and the feature was enabled such that timestamp
information was saved with the data, then PostView can display these Absolute
timestamps (instead of the relative stamps). See following note.
Note: Relative time format, typically uses 00:00:00.0 as the start time and shows other times as
hours, minutes, seconds and tenths which have elapsed since the start time. (Also see
PostView Timebase, page -15.)
Autoscale Current
Channel
For the currently selected channel, automatically generates a scale, in contrast to
manually assigning the scale.
Autoscale All
Channels
Automatically generates a scale for each channel in every chart of the selected group.
Show Grid
(Ctrl+G) Allows grids to be turned off and on for all visible graphs. When a check appears in front
of an item, its indicator is on or visible.
Show Markers
(Ctrl+K) Allows markers to be turned off and on for all visible graphs. When a check appears in
front of an item, its indicator is on or visible.
