Network Viewer (local)

Visualizes the input network. Changing the mouse mode from transforming to picking stops the layout process. To set the mouse mode to picking press 'p'. To change it to transforming press 't'. The tooltip for nodes and edges can be enabled/disabled using the context or the "Options" menu of the node view.

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.

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.
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.
Outline color: Select the color feature that should be used to color the node outline. Please note that only color features are supported.
Default outline color: The node outline 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.
Draw icon outline: Tick this option to draw the outline of an icon with the defined outline color. This option is only available if an icon feature is selected.
Basic outline stroke 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.
Outline stroke width: The feature to use either as the node outline 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.
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.
Use original icon size: Select this option to use the original size of the icon. This option might not work for all image types. This option is only available if an icon feature is selected.
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. If an icon is specified the size defines the width of the icon and its height is computed to keep the aspect ratio.
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 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 node size is applied. If an icon feature is specified the size defines the width of the icon and its height is computed to keep the aspect ratio. Please note that only positive numerical features are supported.
Z coordinate: The selected feature defines the drawing order of the nodes. Nodes with a higher feature value are drawn in front of nodes with a lower feature value.
Draw nodes in reverse order: If ticked nodes are drawn in the reverse order. Thus nodes with a lower z coordinate feature value are drawn in front of nodes with a higher value.

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.
Edge shape: The edge shape that is used to connect adjacent nodes.
Draw directed edge arrow: If this option is ticked the arrow that points to the target of a directed edge is drawn. This option is only enabled if the network contains directed edges.
