功能未正确绘制+装饰性问题d3js

Question

I have two questions. 我有两个问题。 I am trying to plot a function with d3.js. 我正在尝试使用d3.js绘制函数。 I have already come far, but I have two problems. 我已经走得很远了，但是我有两个问题。

As you can see the function which I have defined, y = x. 如您所见，我定义的函数y = x。 Is not correctly plotted along its entire domain. 沿其整个域未正确绘制。 It goes for x from -10 to approx 2.5 and y from 10 to approx 7.5. x的范围从-10到约2.5，y的范围从10到约7.5。 What goes wrong here? 这里出什么问题了？ I do not namely see it. 我没有看到它。

Furthermore I have a cosmetic question. 此外，我还有一个修饰性的问题。 I am trying to create a border around the whole plot on the axis and trying to get the ticks bars to point to the inside of the graph instead of outside. 我试图在轴上的整个图周围创建边框，并试图使刻度线指向图形的内部而不是外部。 In other words, I want to have it more looking like, a Matlab plot, 换句话说，我想让它看起来更像Matlab图

Answer 1

About cosmetic question: you need to set innerTickSize() , outerTickSize() and tickPadding() on your axises with a negative numbers. 关于外观问题：您需要在innerTickSize()设置一个innerTickSize() ， outerTickSize()和tickPadding() 。

About main question: as far as you have scales you should set line's x and y data as a result of scale functions. 关于主要问题：就比例尺而言，应使用比例尺功能设置行的x和y数据。

so your line code will look like this: 因此您的行代码将如下所示：

var line = d3.svg.line() .x(function(d) { return x(dx); }) .y(function(d) { return y(dy); }) .interpolate("linear");
