dc.js

问题 "http://dc-js.github.io/dc.js/examples/stacked-bar.html" I want to roll this kind of dataset into a single bar stacked-bar chart. I changed the speedSumGroup = runDimension.group().reduce(function(p, v) { p[v.Expt] = (p[v.Expt] || 0) + v.Speed; return p; }, function(p, v) { p[v.Expt] = (p[v.Expt] || 0) - v.Speed; return p; }, function() { return {}; }); to speedSumGroup2 = runDimension.groupAll().reduce(function(p, v) { and inspecting the group shows the data rolled up to the single expected.

问题 I am trying to create a barchart (not rowchart) using d3.js and dc.js. I can create the bars ok, but they are all the same colour. I have tried : ordinalColors() scaleOrdinal.range() Renderlet colorAccessor but they all give the one colour for all bars, except colorAccessor which displays no bars at all. I am using dc.js (version 3.0.2) and d3.js (version 5.4.0) and crossfilter (version 1.3.5). Could someone please tell me an approach that will work to get different colours on each of my bars

问题 I'm trying to add a legend to my pie chart but I keep getting the error TypeError: dc.legend is not a function . I'm not sure where to begin on fixing this. I've tried the solution here and here, but no luck. Any help would be greatly appreciated! var geoValue = facts.dimension(function (d) { return d.geo; }); var geoGroup = geoValue.group(); geoChart .width(480) .radius(100) .innerRadius(90) .dimension(geoValue) .group(geoGroup) .transitionDuration(500) .legend(dc.legend().x(250).y(100)) /

问题 I created two tables that relate. When I select one or more items from Table A, Table B is resized according to that selection and vice versa. However, I need to lock the selection of the two tables at the same time. For example, if I click on the sellers Miguel and Sede , in Table B the values and cities corresponding to these two sellers will be rendered. And if in Table B I click on the cities of Faro and Loulé , automatically the sellers Miguel and Sede should be deselected. What happens

问题 I need to complete a sales history test that the company where I work passed me. Where they already get sales data through power bi, and I need to do the same thing but in D3. Here is the image of the graph and tables at the moment: This image shows a graph and two tables, all three of which are directly related. In the graph, the sales value is rendered according to the item (line) that is selected in the table. The default Initial value is the Total line. I'll explain one by one, so I can
