- We'll walk you through the process step by step to convert your graph. In this example, we want to create a curved line graph from this data on cookie sales. Select and highlight the range A1:F2 and then click Insert > Line or Area Chart > Line. The line graph is inserted with straight lines corresponding to each data point.

A graph of the various level curves of a function is called a contour map. Example: Making a Contour Map Given the function [latex]f\,(x,\ y)=\sqrt{8+8x-4y-4x^{2}-y^{2}}[/latex], find the level curve corresponding to [latex]c=0[/latex].
Nov 16, 2022 · The level curves (or contour curves) for this surface are given by the equation are found by substituting \(z = k\). In the case of our example this is, \[k = \sqrt {{x^2} + {y^2}} \hspace{0.25in}\hspace{0.25in} \Rightarrow \hspace{0.25in}\hspace{0.25in}{x^2} + {y^2} = {k^2}\]
Example 1. Let $f(x,y) = x^2-y^2$. We will study the level curves $c=x^2-y^2$. First, look at the case $c=0$. The level curve equation $x^2-y^2=0$ factors to $(x-y)(x+y)=0$. This equation is satisfied if either $y=x$ or $y=-x$. Both these are equations for lines, so the level curve for $c=0$ is two lines.
Dec 29, 2020 · A level curve at \(z=c\) is a curve in the \(x\)-\(y\) plane such that for all points \((x,y)\) on the curve, \(f(x,y) = c\). When drawing level curves, it is important that the \(c\) values are spaced equally apart as that gives the best insight to how quickly the "elevation'' is changing.
Level curves. One way to collapse the graph of a scalar-valued function of two variables into a two-dimensional plot is through level curves. A level curve of a function $f(x,y)$ is the curve of points $(x,y)$ where $f(x,y)$ is some constant value.
Oct 3, 2022 · A graph of the various level curves of a function is called a contour map. Example \(\PageIndex{4}\): Making a Contour Map Given the function \(f(x,y)=\sqrt{8+8x−4y−4x^2−y^2}\), find the level curve corresponding to \(c=0\).

A level curve is just a 2D plot of the curve f(x,y) = k, for some constant value k. Thus by plotting a series of these we can get a 2D picture of what the three-dimensional surface looks like.
