Others here have already mentioned SVGLocatable.getBBox() which is useful for grabbing the bounding box of an element in terms of its own local coordinate system. Unfortunately, as you noticed, this doesn’t take into account any of the transformations done on the element or on its parent elements. There are a couple other functions available that … Read more
In this example the width and height of the svg are set to 8000 x 8000, which seemed to be OK up to about zoom level 9-10. The top and left are set to -4000 x -4000 to center it. Finally, the projection is shifted/offset so that it draws in the center of the svg: … Read more
I am new to D3 but this is what I have found and I mainly figured this out from the sparklines example here. Instead of drawing the line with this code: vis.selectAll(‘path.line’) .data([data]) .enter() .append(“svg:path”) .attr(“d”, d3.svg.line().x(function(d, i) {return x(i); }).y(y)); generate the line separately: var line = d3.svg.line().x(function(d, i) { return x(i); }).y(y) Then … Read more
In a selection method (such as attr) : this.getComputedTextLength(). In a selection of one element, you can say selection.node().getComputedTextLength(). You can also use getBBox for the width and height
⚠ Solution proposed here depends on two libraries marked as unsupported by their authors. To get Graphviz DOT files rendered in Javascript, combine the graphlib-dot and dagre-d3 libraries. The graphlibDot.read() method takes a graph or digraph definition in DOT syntax and produces a graph object. The dagreD3.render() method can then output this graph object to … Read more
There’s no prescribed format, as you can usually redefine your data through various accessor functions (such as hierarchy.children) and array.map. But the format you quoted is probably the most convenient representation for trees because it works with the default accessors. The first question is whether you intend to display a graph or a tree. For … Read more
d3 v5 uses the fetch API and returns a promise requiring the below code. d3.csv(‘yourcsv.csv’) .then(function(data) { // data is now whole data set // draw chart in here! }) .catch(function(error){ // handle error }) In case in the future people want v4. d3 v4 on the other hand uses the XMLHttpRequest method, and does … Read more
If you want to use specific color for pie chart.color(function(d){ return d.data.color }); Then, organize your data as: [ { key: “Cumulative Return”, values: [ { “label”: “One”, “value” : 29.765957771107, “color” : “#8c564b” } , { “label”: “Three”, “value” : 32.807804682612, “color” : “#e377c2” } ] } ]
Dataset: var dataset = [ { “bank”: “Bank 1”, “img”: “Picture1.png” }, { “bank”: “Bank 2”, “img”: “Picture2.png” }, { “bank”: “Bank 3”, “img”: “Picture3.png” } ]; D3 JS code: var w = 1000; var h = 700; var padding = 30; var wpadding = 120; var svg = d3.select(“body”) .append(“svg”) .attr(“width”, w) .attr(“height”, h+padding); … Read more
You probably want to look at: D3 Real-Time streamgraph (Graph Data Visualization), especially the link of the answer: http://bost.ocks.org/mike/path/ In general, I see two ways to deal with the vertical transition problem: oversampling having some linear interpolation between the real point, and the smaller the interval between points, the more “horizontal” the vertical transition will … Read more
