需求描述: 使用svg.js,绘制一个弧线.下图绿色弧线. 准备工作: 1.了解SVG Path中的A指令 详细文档,请戳这里 给定x半径.y半径后,经过指定的两点,可以有2个椭圆,因此两点间有2条弧线,一条大弧线,一条小弧线. 所以,A指令的参数设置如下: 绝对坐标 A rx ry x-axis-rotation large-arc-flag sweep-flag x y 相对坐标 a rx ry x-axis-rotation large-arc-flag sweep-flag dx dy
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
