然而，等高线图是完全一样的。
等高线就像是这幅图的地形图。
And then, the contour plot will be the topographical map for this graph.
这就是一个关于函数等高线图的例子。
因此，等高线图看起来就像这样？
上面这个是f的等高线，黄色的就是双曲线。
That is the contour plot of f with a hyperbola on top of it.
这个就是f等于某个数字的等高线。
那就是为什么等高线图是均匀间隔线的排列的。
现在，在等高线图上取一点。
第二题是找等高线。
等高线图看起来是这样的。
我们来放大它的等高线图。
帽顶：中等高度，前部不是收缩的很厉害。
Crown: Medium height, and not pinched too tightly at the front.

You can also apply contours to plots (as shown in Figure 1, below).
你想问的是，我如何知道它是和等高线垂直的吗？
Do you mean how do I know that it is perpendicular to a level curve?
这些都是现实生活中关于等高线图的例子，有问题吗？
OK, so these are examples of contour plots in real life. OK, no questions?
帽顶：中等高度或偏低，不要选那种又圆又高的帽子。
Crown: Medium or low height, avoid crowns that are full or too high.
