d3.js

问题 Currently I am learning d3js, one of the feature i like to implement is showing tooltip and zooming horizontally. I figured out how to add zooming in the chart ( working fiddle) but feeling little complex in adding tooltip when hover over the points. Is it possible in d3js. Because when zooming we are adding rect element on the svg element. if we add the rect element in the chart means how to make this tooltip works. Need some help from d3 ninjas. var data = [{ date: "10:30:00", price: 36000

问题 I am trying to generate a graph based on some data from a CSV file. My code: <script> var svg = d3.select("body").append("svg") .attr("width", 1000) .attr("height", 1000); function render(data){ var circles = svg.selectAll("circle").data(data); circles.enter().append("circle") .attr("r", 1); circles .attr("cx", function (d){return d[' Monthly Term']}) .attr("cy", function (d){ return d[' Principal Balance']/1000}); circles.exit().remove(); } d3.csv("{% static "data/Total.csv" %}" , type,

问题 I am trying to plot out a graph from the following array, however the console is telling me that the array is not passed to the line function I am receiving the following error: "0: Unable to get property 'x' of undefined or null reference" from the console log Code is as follows : const svgHeight = 400; const svgWidth = 400; const margin = {left:50, right:20, top:20, bottom:30}; const h = svgHeight - margin.top - margin.bottom; const w = svgWidth - margin.right - margin.left; document

问题 As I'm making my first steps into d3.js I couldn't help myself noticing its approach is very similar to jQuery. My question is: When I need to modify multiple CSS properties of a style attribute of matching element is there a shorthand approach, like jQuery or ReactJS provide, like .style({width:100, height:100, backgroundColor:'lightgreen'})` if I need to apply width:100px , height:100px and background-color:lightgreen to a <div> . Sure, I may chain those, but changing multiple properties

问题 I have created a world map in d3 using the geoNaturalEarth1() shown here. I used a geojson map of the world with this projection to get the map as shown in the code below. However, this shows the countries floating in space without a border. I'd like to draw a border around the map projection, so that it looks more like a map. The border would be the flat top/bottom, curved sides as shown in the projection image. Is this possible, and how could I go about doing it? var projection = d3
