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).

Zoom Chart

Zoom Chart causes PostView to display one chart only. For example, if you were viewing

3 charts and desired to get a better view of Chart 2, you could use Zoom to view Chart 2
using the full chart viewing area, as compared to using one third of the area. The zoom
feature can also be invoked by double-clicking in the chart region of the chart for which
you want to apply the zoom.

Once you have zoomed in on a chart, the pull-down menu Zoom option is replaced by a

Restore option. Selecting Restore from the menu will return the main window to its
previous multiple chart viewing status. The restore feature can also be invoked by again
double-clicking in the chart region.

Absolute time
(Ctrl+A)

Places the timebase in a 24-hour absolute time format. For example:
25.2 seconds after 3:08 p.m. would appear as 15:08:25.2.
(Also see PostView Timebase, page -15.)

Relative time
(Ctrl+R)

Places the timebase in a relative time format, typically having 00:00:00.0 as the start time

and having other times represented 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.

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.

(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.

(Ctrl+C)

This function is hidden unless a comment has been added to the data header file. If such

a comment has been entered, then Data Commentary will be visible, allowing you to
display the comment in a message box. The comment feature is supported by certain
acquisition software, and can only be used by PostView versions 3.3 or greater. For
ChartView users: note that commentary can be entered in ChartView’s Setup/Data
Destination dialog box, providing the commentary feature is enabled. To enable the
