An isogon is a contour line for a variable which measures direction.

等角线是用于测量方向的变量的轮廓线。

So, the contour plot looks like that.

现在，在等高线图上取一点。

So, the contour plot, well, let me actually zoom out.

我们来放大它的等高线图。

The second problem is one about writing a contour plot.

第二题是找等高线。

OK, so that's an example of a contour plot of a function.

这就是一个关于函数等高线图的例子。

That is the contour plot of f with a hyperbola on top of it.

上面这个是f的等高线，黄色的就是双曲线。

You can see the same contour repeated on all three items.

你可以看到同样的轮廓一再对所有三个项目。

At all times you can change between contour and point mode.

在任何时候都可以更改的轮廓和点模式。

To help develop our "vision", Brother Wanda used contour lines.

培养我们的“眼力”，罔达修士还运用了“轮廓线训练”法。

And then, the contour plot will be the topographical map for this graph.

等高线就像是这幅图的地形图。

OK, so these are examples of contour plots in real life. OK, no questions?

这些都是现实生活中关于等高线图的例子，有问题吗？

So, here I have a contour plot of a function, and I have a blue vector.

我这里有一个函数的等值线图，还有一个蓝色的向量。

By varying the contour of a shape, you can easily make a page element stand out.

通过变换形状的轮廓线，你很容易就能凸显页面元素。

Having to custom cut each shingle to match the contour of the curves slowed my progress.

为了配合曲线轮廓，必须切削每块木瓦，这减慢了我的进度。

Most page elements have a boxy contour, so this variation will create some unique contrast.

许多页面元素都采用的是框式轮廓，因而这些变化会营造一些独特的对比效果。

But, I trust my computer. And, finally, this one, well, so the contour plot looks a bit complicated.

我相信我的电脑是对的，最后，这一个，它的等高线图比较复杂。

we've seen is how to actually view a function of two variables in terms of its graph and its contour plot.

我们学过怎样认识二元函数,从它的图像和等高线的角度来看。

Now in order to have the exact shadow we need to subtract the contour of our guy from the remaining selection.

为了得到多余阴影的选区，现在我们要从现有选区中减去人物的轮廓。

OK, so another example of contour plots, well, you've probably seen various versions of these temperature maps.

好的，另外一个等高线图的例子，你们可能见过，多种这样的温度图。

So, here's version two of my plot where I've added the contour plot of a function, xy on top of the vector field.

这是第二张函数图,我在上面添加了函数xy的轮廓，放在了向量场上面。

And they had designed a test after the mirror has been constructed to verify that it indeed had the proper contour.

他们在完成主镜建造之后，设计了一个测验，来验证它是否有正确的轮廓。

While shapes are mostly defined by a contrast between elements, they're also defined by their contour, or edge.

虽然形状主要是通过元素间的对比来定义，但它们也可以借助轮廓线或边来定义。

You can use it to construct x-y graphs, contour plots, and image graphs with fine control over graphing attributes.

可以使用它来构造 x-y 图、轮廓图以及可以通过图形属性进行精细控制的图像。
