Note:   Chart Setup Wizard can be started from the File pull-down menu.  Chart Setup Wizard’s use in

PostView is discussed on page -7.

The following table explains PostView toolbar items, while the next page begins a description of PostView
Menu items.  Menu and toolbar items are shown in the figure below.

1

Group Select

This feature indicates the chart group, which is being charted.  Clicking on the down
arrow (

τ

) reveals other chart groups configured by the user.  To select a different chart

group, simply pull down the group list and select the desired group.  The group list can
be obtained by any of the following control options: a) clicking the down arrow (

τ

),

b) using Ctrl + G on the keyboard, c) using the keyboard up or down arrow key, d) using
the page up or page down key.  If using a control option other than “a,” you may need to
select the group select box by repeatable pressing the keyboard’s Tab key until the
group select box is selected.  When this happens the name of the currently selected
group appears in white on a dark background.

2

Open

Accesses the Open Data File window.

3

Print

Sends PostView chart(s) to an assigned printer.

4

Display
Configuration

The Display Configuration button accesses a Display Configuration Setup dialog box.
This box will also be displayed if manual setup is selected during use of the Wizard
Chart Setup program.  Clicking on the button accesses a Display Configuration Setup
box, which displays the configured structure of the groups, charts, and channels.  From
this box you can select the number of charts to be assigned to a specific group.  With
the use of the mouse cursor you can also select a chart or channel for additional editing.
Display Configuration is discussed in more detail, immediately after description of the
pull-down menu options.

Zoom Out
(><)

The Zoom Out button doubles the visible timebase, showing more of the waveform.  For

example, if 10 seconds of information is visible, clicking the Zoom Out button will
show 20 seconds.

6

Zoom In
(<>)

The Zoom In button halves the visible timebase, showing less of the waveform.  For

example, if 10 seconds of information is visible, clicking the Zoom In button will show
5 seconds.

7

Autoscale

Clicking the Auto Scale button adjusts the Y-axis labels so that the waveform fills 90%

of the chart’s range.  Affects all channels of the selected group.

Y-axis Adjust

The Y-axis Adjust fields show the chart’s minimum and maximum for currently selected

charts in the engineering units shown.  Clicking the Auto Scale button automatically
adjusts the Y-axis Adjust fields.

8

Show Grid

Places a grid on the chart (s), or removes the grid if already present.

9

Show Markers

Each chart contains a cross-hair marker that shows the numerical values of time and

magnitude at its present location in the waveform.  The Markers start out at the far left
of every chart, showing the time and magnitude of the first visible point.

Ctrl+Left Mouse Button moves the markers from all the charts in unison.
The Options menu contains a function which allows you to turn markers on and off.

When a check appears in front of this item, its associated indicator is on or visible.
Selecting the menu item toggles the indicator (and the check mark) on and off.

The Trigger Event Marker on the time axis shows the location of the trigger point.
(See figure, PostView TimeBase)

The Stop Event Marker on the time axis shows the location of the stop point.
(See figure, PostView TimeBase)

The Scroll Bar at the bottom of the PostView window allows the waveforms to be scrolled right or left in two ways:

1. When clicked on, the small left and right arrow boxes scroll the waveforms approximately 20%.

 

2. The plain scroll button shows the relative location of the visible region of the waveforms and can be

dragged along the scroll bar to any location desired.
