I am using d3js v3.x to visualize sales data. I have cleaned the data in my SQL Server database and have made sure the field "OrderDate" is of type Date in the database. I have then exported data to csv. I am trying to make a dot chart to show total sales amount per year by using d3js. But when I parse OrderDate to date format, it becomes all null by checking console.table(data). I
我正在使用d3js v3.x来可视化销售数据。 我清理了SQL Server数据库中的数据，并确保数据库中的“OrderDate”字段的类型为Date。 然后我将数据导出到csv。 我想通过使用d3js来制作一个圆点图来显示每年的总销售额。 但是，当我将OrderDate解析为日期格式时，它通过检查console.table（data）变为全空。 我不知道为什么format.parse（）为这些值返回null。 这是我的功能： function draw(data){ "use strict"; v
I'm learning D3, and I can see that I get the same visualization with these two things: var w = 600; var h = 100; var dataset = [1, 6, 3, 4, 10, 4, 9] var svg = d3.select("body").append("svg") .attr("height", h) .attr("width", w) var xScale = d3.scale.linear() .domain([0, dataset.length]) .range([0, w]); Using the height attribute: var yScale = d3.scale.linear() .
我正在学习D3，并且我可以看到我用这两样东西获得了相同的可视化效果： var w = 600; var h = 100; var dataset = [1, 6, 3, 4, 10, 4, 9] var svg = d3.select("body").append("svg") .attr("height", h) .attr("width", w) var xScale = d3.scale.linear() .domain([0, dataset.length]) .range([0, w]); 使用高度属性： var yScale = d3.scale.linear() .domain([0, d3.max(dataset)]) .rang
I have a stacked bar chart. And I'd like a draw a line like grouping few bars of a stacked bar chart. Something like this. So to do this I need to find the y coordinate of the 2nd and the last bar. Some one please help in drawing those line using d3. JS: var width = 750, height = 500; var x = d3.scale.ordinal() .rangeRoundBands([0, width], .1); var y = d3.s
我有一个堆积的条形图。 我想画一条线，像堆积条形图中的几条。 像这样的东西。 所以要做到这一点，我需要找到第二个和最后一个酒吧的y坐标。 有人请帮助使用d3绘制这些线。 JS： var width = 750, height = 500; var x = d3.scale.ordinal() .rangeRoundBands([0, width], .1); var y = d3.scale.linear() .rangeRound([height, 0]); var color = d3.scale.ordinal()
I need some help in getting the X and Y Co-ordinates of a stacked bar chart for each rect in the stacked bar chart. I'm here creating a new rectangle on hover. I want the to be created on right side top of the hovered rectangle of the stacked bar chart. Here's the mouse over function I've defined, problem is it's giving the y value of only the first rect of a stacked bar. f
我需要一些帮助，以获得堆叠条形图中每个矩形的堆积条形图的X和Y坐标。 我在这里创建一个新的矩形悬停。 我想要在堆叠条形图的悬浮矩形的右侧顶部创建。 下面是我定义的鼠标悬停功能，问题是它只给出堆叠酒吧的第一个矩形的y值。 function movein() { var allRect = d3.selectAll("rect") // .transition() // .duration(300) .attr("opacity", 0)
I am trying to use Ember data with already built REST api. It works fine for top level routes, for example I have route for courses on api side like following: app.get('/courses', app.controllers.courses.findAll) app.get('/courses/:id', app.controllers.courses.findById) Above works fine and I can easily get data with Ember Data. But problem arises with routes that have multiple levels. For e
我正在尝试使用已经构建REST API的Ember数据。 它对顶级路线工作正常，例如，我有如下的API路线课程路线： app.get('/courses', app.controllers.courses.findAll) app.get('/courses/:id', app.controllers.courses.findById) 上述工作正常，我可以轻松地使用Ember Data获取数据。 但是，具有多个级别的路由会出现问题。 例如，课程可以有多个主题，主题可以有多个讲座，因此它们的路由在api一侧被定义为这样。 主题： a
I have an object in the below format and I need to get all values from the Price property at all levels of the object. var o = { Id: 1, Price: 10, Attribute: { Id: 1, Price: 2, Modifier: { Id: 34, Price: 33 } } }; I was thinking of LinqToJS and jquery.map() methods but I'd like to get a method as generic as possible. I
我有一个以下格式的对象，我需要从该对象的所有级别的Price属性中获取所有值。 var o = { Id: 1, Price: 10, Attribute: { Id: 1, Price: 2, Modifier: { Id: 34, Price: 33 } } }; 我在想LinqToJS和jquery.map()方法，但我想尽可能通用一种方法。 我试过这个，但它只在第一级工作： var keys = $.map(o, function(value, key) { if (key == "P
I'm trying to create a copy function in pure JS, so no flash. The problem I've got is that I don't want to show the copy button when the browser doesn't support copying to clipboard. I'm using the document.execCommand('copy') method to do the copying to clipboard but the support for this isn't the best. For example, safari has the execCommand function but doesn
我试图在纯JS中创建一个复制函数，所以没有闪光。 我得到的问题是，当浏览器不支持复制到剪贴板时，我不想显示复制按钮。 我正在使用document.execCommand('copy')方法来复制到剪贴板，但对此的支持并不是最好的。 例如，safari具有execCommand功能，但不支持copy参数。 这意味着我不能简单地检查该函数是否存在。 由于这种狡猾的支持，我认为我将不得不采取浏览器检测的方式，就像github一样，我通过查看zerocli
This question already has an answer here: Equivalent of String.format in jQuery 20 answers String.format = function () { // The string containing the format items (e.g. "{0}") // will and always has to be the first argument. var theString = arguments[0]; // start with the second argument (i = 1) for (var i = 1; i < arguments.length; i++) { // "gm"
