DC, Crossfilter dimension: multiple columns as different keys?

I have two date columns (startYear and endYear) for each of 50 apps. The earliest startYear is 1994 and the latest endYear is 2030. I want to add a time widget bar chart into an existing DC dashboard. There will be one bar per year from 1994 to 2030 and each bar should show the number of apps in existence in that year. I'm aiming for the following data structure in my crossfilter group:

DC,Crossfilter维度:多列作为不同的键?

我有两个日期列(startYear和endYear)为每个50应用程序。 最早的开始年份是1994年,最晚的结束年份是2030年。 我想将时间小工具条形图添加到现有的DC仪表板中。 从1994年到2030年每年会有一个酒吧,每个酒吧应该显示当年现有的应用数量。 我在我的交叉过滤器组中寻找以下数据结构: group(36) = [ {key:1994, value:1}, {key:1995, value:4}, {key:1996, value:5}, {key:1997, value:10}, {key:1998, value:30}, ... etc ]

dc.js / crossfilter performance issue 12,000+ rows of CSV data

I'm having some performance issues with using dc.js and crossfilter. I'm creating a set of graphs displaying different dimensions of some cycling data (code here, data here, viewable here). The charts render after a few second or two, but the main performance issues occur when clicking any of the graphs - the transition animations kind of "snap" after a delay, and it's a b

dc.js / crossfilter性能问题12,000+行CSV数据

我在使用dc.js和crossfilter时遇到了一些性能问题。 我创建了一组显示一些骑行数据的不同尺寸的图形(代码在这里,数据在这里,可以在这里查看)。 图表在几秒或两秒后呈现,但是当点击任何图表时会出现主要的性能问题 - 延迟后的过渡动画类型为“快照”,这有点刺耳。 我还注意到,仅仅删除页面顶部的空白折线图会导致其余三个图表在转换恢复正常时表现更好。 我已经看过一些类似的问题,但这并不一定适用,因为我一次不会分

reload files in Node.js?

EDIT: Use http://github.com/isaacs/node-supervisor; This is an old question and the code example is made with an outdated Node.js API. Any ideas on how I could implement an auto-reload of files in Node.js? I'm tired of restarting the server every time I change a file. Apparently Node.js' require() function does not reload files if they already have been required, so I need to do some

在Node.js中重新加载文件?

编辑:使用http://github.com/isaacs/node-supervisor; 这是一个老问题,代码示例是使用过时的Node.js API制作的。 关于如何在Node.js中实现文件的自动重新加载的任何想法? 每次更改文件时,我都厌倦了重新启动服务器。 显然Node.js的require()函数不会重载文件,如果它们已经被需要的话,所以我需要做这样的事情: var sys = require('sys'), http = require('http'), posix = require('posix'), j

我无法通过使用JavaScript SDK的Facebook登录获取用户访问令牌(https://developers.facebook.com/docs/reference/javascript/FB.getLoginStatus) 在response.authResponse.accessToken中通过此函数返回的令牌实际上是一个应用程序访问令牌。 有了这个不能,我不能像在Graph API Explorer中那样访问公共配置文件。 https://graph.facebook.com/v2.2/993673107328394不会像Graph API Explorer中那样工作。 谢谢, FB.get

How do I refresh React state after running navigator.pop()?

While working with React Native, I have a few components that are pushed on top of each other, some of which change the state of the component below them, like so: Social -> Groups -> Add Group However, when I run navigator.pop() to get back to the previous component (for example, after adding a group to a user's account), the component underneath (in this case, 'Groups') wo

在使用React Native时,我有几个组件相互重叠,其中一些组件会改变组件的状态,如下所示: 社交 - >群组 - >添加群组 但是,当我运行navigator.pop()返回到以前的组件(例如,在向用户的帐户添加组之后),下面的组件(本例中为“组”)将不会刷新州。 我在这里做错了什么? 事实证明,我可以通过在'组' componentWillUpdate上插入一个componentWillUpdate来解决这个问题,也就是说,只要Groups组件更新,它
