ES6 module of Parallel Coordinates, based on d3 v5 modules
npm install parcoord-esES6 module of Syntagmatic's Parallel Coordinates (aka. parcoords). This library is completely based on D3 V5 API.
Please refer to Parallel Coordinates's project page for concepts and API usage
All examples of the original project has been verified. You can play with them via running:
``
npm install
npm run dev
# parcoords.brushExtents(extents) supports 1D multi brushes:
1D brush <>
`javascript`
.brushMode("1D-axes")
.brushExtents({"2": [3,4]});
1D multi brush <>
`javascript
.brushMode("1D-axes-multi")
.brushExtents({"2": [[3,4], [6,8], [10, 14]]});
`
when parameter extents is not provided, this function returns
`
const extents = parcoords.brushExtents();
// format is:
{
extents,
selection: {
raw, //raw coordinate
scaled //y-scale transformed
}
}
# parcoords.mark([values])
allows user to permanently highlight a data element in chart
`
const data = [...];
const pc = ParCoords().data(data)...;
parcoords.mark(data.filter(d => d.volume > 10));
Please refer to marking demo for details
# parcoords.unmark()
clears all permanently highlighted data that is added by mark([values])
# parccords.on(function(brushed, args){})
adds brush arguments to brushstart, brush, and brushend events.
`
parcoords.on('brushstart', function(brushed, args){
const {
selection: {
raw, //raw coordinate
scaled //y-scale transformed
},
node, // svg node
axis // dimension name
} = args;
})
Please refer to brushing with arguments demo for details
