这是我解决它的方法。我有一个变量moveOut
,所以我可以在原始节点位置和我移动到的节点之间切换。因此,根据moveOut
I 的值改变远离中心的移动比例。
var thisNode = circleViewNode.filter(function(d){
//console.log(d)
return d.origin != 'EquivalenceSets' && d.hasRelationship != true;
});
thisNode.each(function(d){
thisNodeSize = d.thisRadius;
});
if(!moveOut){
thisScale = innerModelRadius - thisNodeSize*1.5;
moveOut = true;
} else {
thisScale = innerModelItemRadius + (outerModelItemRadius - innerModelItemRadius)/2;
moveOut = false;
}
thisNode.each(function(d){
//console.log(d);
var centerOfCircle = [width/2,height/2]; //get center
//var centerOfCircle = [arcCenter.x, arcCenter.y];
var thisPosition = [d.x, d.y]; //get position of current node
//thisVector = [center[0]-thisPosition[0], center[1]-thisPosition[1]],
var thisVector = [thisPosition[0] - centerOfCircle[0], thisPosition[1] - centerOfCircle[1]];
var thisVectorX = thisVector[0];
var thisVectorY = thisVector[1];
var xSquared = Math.pow(thisVector[0],2);
var ySquared = Math.pow(thisVector[1],2);
var normalVector = Math.sqrt(xSquared + ySquared); //using pythagoras theorum to work out length from node pos to center
//console.log(d);
thisVectorX= thisVectorX/normalVector;
thisVectorY= thisVectorY/normalVector;
// d.x = centerOfCircle[0]+(thisVectorX*thisScale);// + -38.5;
// d.y = centerOfCircle[1]+(thisVectorY*thisScale);// + -20;
d.x = centerOfCircle[0]+(thisVectorX*thisScale); //thisScale gives the ability to move back to original pos
d.y = centerOfCircle[1]+(thisVectorY*thisScale);
//}
})
.transition().duration(1000)
.attr("transform", function(d)
{
//console.log(d.hasRelationship);
//console.log(d.y);
return "translate(" + d.x + "," + d.y + ")"; //transition nodes
});
