There are several different forms in which a node can be displayed, and these are known as node styles. There is a default style for the whole net, but each node can be set to its own style individually, which overrides the default.
Default Style: To set the default style for the active net, make sure that no nodes are selected, and then choose the desired style from the Style menu, or right-click on the net background and choose Modify → Default Node Style. If some nodes don't change, perhaps they have overriding styles (see below).
To have some nodes override the default style, select them and then choose the desired style from the Style menu. If you have given some nodes an overriding style, but now you want them back to the default style, select them and choose Style → Default.
Forms: The various node forms are:
• Labeled-Box: |
Draws a box whose shape and color are determined by the node kind, with the name/title of the node written within it (deterministic nodes will be displayed using a thick border). |
• Belief-Bar: |
Draws a bar graph showing the current beliefs for each state of the node. |
• Meter: |
Displays a needle meter showing the mean value for continuous nodes and the current belief for discrete nodes. |
• Hidden: |
Doesn't draw anything (you can also hide the links). |
• Circle: |
Displays the node as a small circle, without text. See the Index of this example. |
Other Styles: Keep in mind
that you can also change other aspects of the node
style, such as the size, font,
color, and labeling
of the nodes.
