The following node is available in the Open Source KNIME predictive analytics and data mining platform version 2.7.1. Discover over 1000 other nodes, as well as enterprise functionality at http://knime.com.

Network Viewer

Visualizes the input network. Changing the mouse mode from transforming to picking stops the layout process. In order to start the layout again change the layout. To set the mouse mode to picking press 'p'. To change it to transforming press 't'.

The node returns an image object of the network which can be used in reports for example.

Notice: The node does not support hypergraphs or empty edges. You can use the edge degree filter with a minimum degree of 1 and a maximum degree of 2 to filter out the unsupported edges.

Dialog Options

General
Layout
The layout algorithm to use.
Layout time (sec.)
The time to layout the graph. This option is only enabled for iterative layouts that need some time to layout the graph.
Background color
Click the button to change the background color of the view.
Selection color
Click the button to change the label color of selected nodes and edges.
Background image
The graph feature that should be used as graph background.
Renderer
The renderer that should be used to render the background image. This option is only enabled if the selected feature allows to select different renderer.
Width
The image width.
Height
The image height.
Show interactive feature table in node view
The node view will also contain an interactive feature table if this option is ticked. The interactive feature table displays the values for the defined features for the selected nodes and edges.
Image type
The type of the result image.
Layout Settings
Layout depending options
The Layout Settings tab is only visible if the selected layout on the General tab provides additional settings options. The options might differ depending on the selected layout.
Node Layout
Label
The feature to use for the node label. Select <NONE> for no label and <ID> if the id of the object should be used.
Position
Defines the position of the node label. The "Auto" option places the label depending on the nodes position. All other options places the label at a fixed position e.g. "Center" places the label in the center of the node whereas "North" places the label always at the top of a node.
Font
Click the button to change the font of the node labels. The text box next to the button shows a preview of the currently selected font.
Font size
The feature to use either as the font size or to scale the basic font size. If the feature is of the integer or long type, its value is used directly as the font size, otherwise the font size is scaled by multiplying the basic node size by the returned feature value. If no size feature is selected or if the selected feature does not return a value the basic size is applied. Please note that only numerical features are supported.
Label color
Select the color feature that should be used to color the node label. Please note that only color features are supported.
Default label color
The node label color that is used by default e.g. if no color feature is selected or if the selected feature does not return a value for a given node. Click the button to change the default color.
Paint BG
Tick this option to have the label background painted.
BG color
Select the color feature that should be used to color the node label background. Please note that only color features are supported.
Default BG color
The node label background color that is used by default e.g. if no color feature is selected or if the selected feature does not return a value for a given node. Click the button to change the default color.
Shape
Select the feature that defines the node shape. Notice that only shape features are supported.
Default shape
The node shape that is used by default e.g. if no shape feature is selected or if the selected feature does not return a value for a given node.
Icon
Select the feature that should be used for the node icon. This options allows you to show images or chemical structures as the node icon instead of a shape. The shape is used instead if no icon is available.
Renderer
The renderer that should be used to render the value of the selected feature. The available renderer depend on the selected icon feature and is thus only enabled if an icon feature is selected. Notice that the renderer option is also disabled if an image feature e.g. png is selected since the image is taken directly and thus no renderer is needed.
Fill color
Select the color feature that should be used to color the nodes. Please note that only color features are supported.
Default fill color
The node color that is used by default e.g. if no color feature is selected or if the selected feature does not return a value for a given node. Click the button to change the default color.
Basic size
The node size that is used by default e.g. if no size feature is selected or if the selected feature does not return a value for a given node.
Size
The feature to use either as the node size or to scale the basic node size. If the feature is of the integer or long type, its value is used directly as the node size, otherwise the node size is scaled by multiplying the basic node size by the returned feature value. If no size feature is selected or if the selected feature does not return a value the basic size is applied. Please note that only numerical features are supported.
Edge Layout
Label
The feature to use for the edge label. Select <NONE> for no label and <ID> if the id of the object should be used.
Font
Click the button to change the font of the edge labels. The text box next to the button shows a preview of the currently selected font.
Font size
The feature to use either as the font size or to scale the basic font size. If the feature is of the integer or long type, its value is used directly as the font size, otherwise the font size is scaled by multiplying the basic font size by the returned feature value. If no size feature is selected or if the selected feature does not return a value the basic font size is applied. Please note that only numerical features are supported.
Label color
Select the color feature that should be used to color the edge label. Please note that only color features are supported.
Default label color
The edge label color that is used by default e.g. if no color feature is selected or if the selected feature does not return a value for a given edge. Click the button to change the default color.
Paint BG
Tick this option to have the edge background painted.
BG color
Select the color feature that should be used to color the edge label background. Please note that only color features are supported.
Default BG color
The edge label background color that is used by default e. g. if no color feature is selected or if the selected feature does not return a value for a given edge. Click the button to change the default color.
Color
Select the color feature that should be used to color the edges. Please note that only color features are supported.
Default color
The edge color that is used by default e.g. if no color feature is selected or if the selected feature does not return a value for a given edge. Click the button to change the default color.
Basic width
The stroke width that is used by default e.g. if no width feature is selected or if the selected feature does not return a value for a given edge.
Width
The feature to use either as the edge stroke width or to scale the basic stroke width. If the feature is of the integer or long type, its value is used directly as the stroke width, otherwise the stroke width is scaled by multiplying the basic width by the returned feature value. If no width feature is selected or if the selected feature does not return a value the basic size is applied. Please note that only numerical features are supported.
