Creates a configuration object for the edge-filter-lens plugin in G6. This plugin creates a lens that filters and displays edges within a specific area.
Usage
edge_filter_lens(
key = "edge-filter-lens",
trigger = c("pointermove", "click", "drag"),
r = 60,
maxR = NULL,
minR = 0,
scaleRBy = "wheel",
nodeType = c("both", "source", "target", "either"),
filter = NULL,
style = NULL,
nodeStyle = list(label = FALSE),
edgeStyle = list(label = TRUE),
preventDefault = TRUE,
...
)Arguments
- key
Unique identifier for the plugin (string, default: NULL).
- trigger
Method to move the lens: "pointermove", "click", or "drag" (string, default: "pointermove").
- r
Radius of the lens (number, default: 60).
- maxR
Maximum radius of the lens (number, default: NULL - half of the smaller canvas dimension).
- minR
Minimum radius of the lens (number, default: 0).
- scaleRBy
Method to scale the lens radius (string, default: "wheel").
- nodeType
Edge display condition: "both", "source", "target", or "either" (string, default: "both").
- filter
Filter out elements that are never displayed in the lens (JS function, default: NULL).
- style
Style of the lens (list, default: NULL).
- nodeStyle
Style of nodes in the lens (list or JS function, default: list(label = FALSE)).
- edgeStyle
Style of edges in the lens (list or JS function, default: list(label = TRUE)).
- preventDefault
Whether to prevent default events (boolean, default: TRUE).
