crossfilter

问题 I have the following dc.js series chart: var data = [ {day: 1, service: 'ABC', count: 100}, {day: 2, service: 'ABC', count: 80}, {day: 4, service: 'ABC', count: 10}, {day: 7, service: 'XYZ', count: 380}, {day: 8, service: 'XYZ', count: 400} ]; var ndx = crossfilter(data); var dim = ndx.dimension(function (d) { return [d.service, d.day]; }); var grp = dim.group().reduceSum(function(d) { return +d.count; }); var chart = dc.seriesChart('#graph') .width(620) .height(175) .chart(function(c) {

问题 I have a CSV dataset that I am exploiting with dc.js (crossfilter). Date, Country 1,Country 2,Country 3,Country 4,Country 5,Country 6,Target country (...) 2014/12/11, USA, France, UAE, (...), Iraq The thing I am trying to do is to plot a row chart with one row per country. Here's my solution as of today: var countries = ndx.dimension(function(d) { var list = []; list.push(d["Country 1"]); if (d["Country 2"]) {list.push(d["Country 2"]);}; if (d["Country 3"]) {list.push(d["Country 3"]);}; if (d

问题 Has any one used dc.js with Angular2+ application. Any help or pointers will be appreciated. I am able to make my application running on normal html/java-script. Now I need to implement the same in Angular 2+ application. 回答1: Edit : A couple of weeks later I have a much better understanding and can maybe give some better instructions, so here It goes: After generating the angular project, install dc , its typefiles, and all needed dependencies like this: npm i --save dc @types/dc

问题 I'm fairly new to the dc.js/crossfilter/d3 trifecta, and have a question about grouping variables for building a stacked area chart. I've been following tutorials like this one that show how to generate a time series chart. This has been really useful, however my method of defining the .group() method of the chart is slightly different. In the example, the author has data of the form {'date': somedate, 'http_404': 20, 'total': 340 ... } where each type of http request has some sort of
