Hello All,
is there a way to constrain all the data in a visualization to the area with in the visualization?
Here is an example:
{
"$schema": "https://vega.github.io/schema/vega/v5.json",
"width": 700,
"height": 500,
"padding": 0,
"autosize": "none",
"signals": [
{ "name": "cx", "update": "width / 2" },
{ "name": "cy", "update": "height / 2" },
{ "name": "nodeRadius", "value": 8 },
{ "name": "nodeCharge", "value": -100 },
{ "name": "linkDistance", "value": 30 },
{ "name": "static", "value": true },
{
"description": "State variable for active node fix status.",
"name": "fix", "value": false,
"on": [
{
"events": "symbol:mouseout[!event.buttons], window:mouseup",
"update": "false"
},
{
"events": "symbol:mouseover",
"update": "fix || true"
},
{
"events": "[symbol:mousedown, window:mouseup] > window:mousemove!",
"update": "xy()",
"force": true
}
]
},
{
"description": "Graph node most recently interacted with.",
"name": "node", "value": null,
"on": [
{
"events": "symbol:mouseover",
"update": "fix === true ? item() : node"
}
]
},
{
"description": "Flag to restart Force simulation upon data changes.",
"name": "restart", "value": false,
"on": [
{"events": {"signal": "fix"}, "update": "fix && fix.length"}
]
}
],
"data": [
{

"values":[
{

},
{

"values":[
{
"source":0,
"target":1
},
{
"source":2,
"target":3
}
]
}
],
"scales": [
{
"name": "color",
"type": "ordinal",
"domain": {"data": "node-data", "field": "group"},
"range": {"scheme": "category20c"}
}
],
"marks": [
{
"name": "nodes",
"type": "symbol",
"zindex": 1,
"from": {"data": "node-data"},
"on": [
{
"trigger": "fix",
"modify": "node",
"values": "fix === true ? {fx: node.x, fy: node.y} : {fx: fix[0], fy: fix[1]}"
},
{
"trigger": "!fix",
"modify": "node", "values": "{fx: null, fy: null}"
}
],
"encode": {
"enter": {
"fill": {"scale": "color", "field": "group"},
"stroke": {"value": "white"}
},
"update": {
"size": {"signal": "2 * nodeRadius * nodeRadius"},
"cursor": {"value": "pointer"}
}
},
"transform": [
{
"type": "force",
"iterations": 300,
"restart": {"signal": "restart"},
"static": {"signal": "static"},
"signal": "force",
"forces": [
{"force": "center", "x": {"signal": "cx"}, "y": {"signal": "cy"}},
{"force": "collide", "radius": {"signal": "nodeRadius"}},
{"force": "nbody", "strength": {"signal": "nodeCharge"}},
{"force": "link", "links": "link-data", "distance": {"signal": "linkDistance"}}
]
}
]
},
{
"type": "path",
"from": {"data": "link-data"},
"interactive": false,
"encode": {
"update": {
"stroke": {"value": "#ccc"},
"strokeWidth": {"value": 0.5}
}
},
"transform": [
{
"type": "linkpath",
"require": {"signal": "force"},
"shape": "line",
"sourceX": "datum.source.x", "sourceY": "datum.source.y",
"targetX": "datum.target.x", "targetY": "datum.target.y"
}
]
}
]
}
What I want to, is to make it so that all 10 data nodes are visible, but they aren't. Is there a simple way to force this that I have missed or some more complicated way to do it?
Thank you!
