Understanding Groups, Charts, and Channels
As indicated in the figure on page -3, when no display configuration file is found, PostView opens the
Chart Setup Wizard to assist you in creating a display file. To make the best use of Chart Setup Wizard you
need to understand the relationship of Groups, Charts, and Channels. The Chart Setup Wizard feature is
discussed immediately following this text.
Group. “Group” refers to a group of charts. You can add and remove
groups to your display, and you can add or remove charts to each group.
Depending on the capabilities of your PC, you can have up to 64 groups
assigned to your display.
Note: PostView can only display data from one group at a time.
Chart. A “Chart” is a display area containing up to four channels. You can
assign up to 16 charts per group. Charts can be displayed with or without
gridlines.
Channel. “Channel” refers to a signal channel. You can have up to 4
channels assigned to one chart. Channels will be displayed in units of °C,
°F, °K, °R, mV, V, or user defined units, depending on the configuration and
type of signal conditioning card which was used during data acquisition.
Chart Setup Wizard
Introduction
The Chart Setup Wizard feature allows you to create PostView’s initial chart display configuration with an
automated or manual method. When PostView can not locate a display configuration file, it automatically
accesses the Chart Setup Wizard feature. If a display configuration file is located, PostView bypasses the
Chart Setup Wizard.
Note: You can manually activate the Chart Setup Wizard from the File pull-down menu. Activating the
Chart Setup Wizard will reset an existing display configuration. Prior to manually activating the
Wizard feature, a “New Display Setup” box will appear to remind you of the display reset. You
can then activate Wizard by selecting “OK,” or discontinue by selecting “cancel.”
Note: You can edit the display configuration file without use of the Chart Setup Wizard by using the
Display Configuration Setup dialog box. This box can be accessed from Setup in the File pull-
down menu, or by clicking on the Chart Setup button in PostView’s toolbar. This method of
display editing is discussed in the section, Display Configuration, beginning on page -9.
The chart display setup determines how your PostView window will appear in regard to the following:
•
number of chart groups available for viewing
•
number of charts shown for each selected group
•
the number of overlapping channels in each chart (not to exceed 4)
You can choose to manually create a display configuration, or have one created automatically. The
automatic setup method offers three choices: Simple, Moderate, and Advanced.
