冻结力导向网络图并在D3中进行拖动(Freezing force directed network graph and make draggable in D3)

我试图完全冻结d3中的强制定向网络! 我已经尝试将摩擦值设置为0,但网络变得更加精简,节点仍然略微悬停。

var force = d3.layout.force()
.charge(-220)
.linkDistance(70)
.friction(0);

我还希望我的节点可以拖动,即拖动时移动位置。

最终,我试图得到类似于Cytoscape js的东西,看起来像这样

谢谢!


I am trying to freeze a force directed network in d3 completely! I have tried setting the friction value to 0, but the network becomes more condensed and the nodes still hover slightly.

var force = d3.layout.force()
.charge(-220)
.linkDistance(70)
.friction(0);

I also want my nodes to be draggable i.e. move position when they are dragged.

Ultimately, I'm trying to get something similar to Cytoscape js which looks like this.

Thanks!

您可以通过遍历原型链找到继承属性的对象:

function origin(obj, prop) {
    for (; obj != null; obj=Object.getPrototypeOf(prop))
        if (Object.prototype.hasOwnProperty.call(obj, prop))
            return obj;
    return obj;
}
// or, recursively:
function origin(obj, prop) {
    if (obj == null || Object.prototype.hasOwnProperty.call(obj, prop))
        return obj;
    return origin(Object.getPrototypeOf(obj), prop);
}

那你可以做

for (var p in car)
    console.log(p, origin(car, p), origin(car, p).constructor.name)
honkHorn, {…}, Car
drive, {…}, Vehicle
turnOn, {…}, Vehicle

You can find the object from which a property is inherited by traversing the prototype chain:

function origin(obj, prop) {
    for (; obj != null; obj=Object.getPrototypeOf(prop))
        if (Object.prototype.hasOwnProperty.call(obj, prop))
            return obj;
    return obj;
}
// or, recursively:
function origin(obj, prop) {
    if (obj == null || Object.prototype.hasOwnProperty.call(obj, prop))
        return obj;
    return origin(Object.getPrototypeOf(obj), prop);
}

Then you can do

for (var p in car)
    console.log(p, origin(car, p), origin(car, p).constructor.name)
honkHorn, {…}, Car
drive, {…}, Vehicle
turnOn, {…}, Vehicle
