Column and bar charts are staples of every visualization library. They also make a great project for combining the essential pieces of D3 like selections, scales, axes, and SVG elements. This lesson walks you through the process of creating an essent…

Similar to line charts, area charts are great for displaying temporal data. Whether you’re displaying a single set of data or multiple sets using an overlapping or stacked layout, D3 provides APIs to make the process straightforward. This lesson walk…

Line charts are often used to plot temporal data, like a stock price over time. In this lesson we’ll see how to use D3 APIs to create our own simplified version of the charts seen on Google Finance. var margin = { top: 10, right: 20, bottom: 65, left…

Scatter plots, sometimes also known as bubble charts, are another common type of visualization. They’re extremely versatile thanks to their ability to display multiple dimensions of data simultaneously using x and y position, opacity, color, and even…

1. 条形图(Bar Chart)需要的数据格式类型如下: ["Luke Skywalker", "Darth Vader", "Yoda", "Princess Leia"] [2, 4, 1, 1] 2. Bar Chart代码示例: $(function () { $('#container').highcharts({ chart: { type: 'bar' }, xAxis: { categories: ['Jan…

使用angular resource载入中priorityData.json中间json数据,结合D3绘制甜甜圈图.执行index.html其结果见于图.: priorityData.json中json数据例如以下: { "priority":{ "Blocker":12, "Critical":18, "Major":5, "Minor":30, "Trivial":24 } } in…

You probably use a framework or standalone library to load data into your apps, but what if that’s overkill for your needs? What if you’re just putting together a quick demo? This lesson demonstrates D3’s APIs for loading data on its own, as well as…

前文中已经提到,SVG从诞生之初起就可以非常方便地使用javascript脚本语言来进行其DOM对象的控制.当然,控制的方法有很多,有直接控制SVG对象的方法,例如使用原生js:有帮你封装一下图形接口再进行直接控制的js类库,如 Raphaël.但是正如我在第一篇文章中所说,d3作为一个中间型类库还能脱颖而出的重要原因,在于它突破了其他类库的那种直接控制表现层的机制,而采用了对于web图形处理领域较为新颖的数据驱动机制(2011),并获得了极大的成功. 数据驱动的历史 数据驱动编程并不是一个新鲜…

var line_generator= d3.svg.line() .x(function (d,i) { return i; }) .y(function (d) { return d; }) 错误:TypeError: d3.svg.line is not a function 原因: 你使用D3 v4 .从版本4开始,没有 d3.svg ,因此出现错误消息.您要查找的行生成器现在定义为d3.line(). 如果您仍在使用版本3,则会是 d3.svg.line(). 解决方法: var li…

 目录 1.用js操作chart, 2.tooltip template鼠标悬浮显示内容, 3.双坐标轴,axisCrossingValues: [0, 30],3指的是跨越横坐标轴标签项数,显示在右侧 4标签永远在下边,categoryaxis里多加个series-axis,valueAxes里加个 axisCrossingValue: [0, @int.MinValue] 5.更新数据 6.全部代码 7.图中只有一种柱,统一设置颜色,用.Column().Color("#5EB6E4&quo…
