All the answers above misunderstood Øystein Amundsen’s question. The only way to stabilize the force upon it starts is to set node.x and node.y a proper value. Please note that the node is the data of d3.js, not the represented DOM type. For example, if you load nodes = [{“id”: a}, {“id”: b}, {“id”: c}] … Read more
Yes. First I would restructure your data for easier iteration, like this: var series = [ [{time: 1, value: 2}, {time: 2, value: 4}, {time: 3, value: 8}], [{time: 1, value: 5}, {time: 2, value: 9}, {time: 3, value: 12}], [{time: 1, value: 3}, {time: 2, value: 2}, {time: 3, value: 2}], [{time: 1, value: … Read more
for remote data.json replace : d3.tsv(“data.tsv”, function(error, data) {…} with : d3.json(“data.json”, function(error, data) { console.log(data); // this is your data }); for local data: var myData = { {date:’2013-05-01′, frequency:99}, {date:’2013-05-02′, frequency:24} }; function draw(data) { console.log(data); // this is your data } draw(myData);
In d3 v5 the API for fetching data has changed quite a bit, which became necessary as the underlying workings have switched from using XMLHttpRequest to the Fetch API. In prior versions of D3 up to v4 your code would have behaved as you expected printing the single resulting array. The new API for d3.csv(), … Read more
This question is a variation of the How to create elements based on data? or How to dynamically append elements? pattern. In my opinion your approach will be overly complex and cluttered because you need to duplicate functions to create elements in your data. This doesn’t seem to be an elegant solution. I would prefer … Read more
Update Angular and SASS agreed on supporting ::ng-deep (instead of >>> or /deep/) a while ago until ::slotted or whatever makes it into browser standards becomes available in all browsers. ViewEncapsulation.Emulated (default) That’s by design. Angular adds class names unique to components and rewrites the added styles to only apply to the components where they … Read more
In my opinion, the force layout is unsuitable for the purpose of placing labels on a map. The reason is simple — labels should be as close as possible to the places they label, but the force layout has nothing to enforce this. Indeed, as far as the simulation is concerned, there is no harm … Read more
The “right” way to do this is to register your chart in the dc registry with dc.registerChart You just need to implement .redraw() and .render() on some object (your chart or a wrapper), and pass that object as the first argument. Put it in the same group (second arg) as the charts it should respond … Read more
It is quite easy, just add some more “key” : “value” pairs. Example: “children”: [ { “name”: “Google”, “size”: 3938, “url”: “https://www.google.com” }, { “name”: “Bing”, “size”: 3938, “url”: “http://www.bing.com” } ] Of course, in your d3 code you then need to append <svg:a> tags and set their xlink:href attribute. Here is some html and … Read more
My answer is close to Jan van der Laan’s, but you can simplify things slightly because you don’t need to compute the geographic centroid; you only need the bounding box. And, by using an unscaled, untranslated unit projection, you can simplify the math. The important part of the code is this: // Create a unit … Read more
