For example The level surface of at level is the unit sphere (the sphere of radius 1 centered at the origin) When we generically have a curve We call these level curves or contours For example The level curves of are parabolas A graph of (some of) the level curves of a function is called a contour plot (it looks like a topographical map) You've probably seen level curves (or contour curves, whatever you want to call them) before If you've ever seen the elevation map for a piece of land, this is nothing more than the contour curves for the function that gives the elevation of the land in that area Of course, we probably don't have the function that gives the elevation, but we can at least graph the contour curvesThe level curves (or contour lines) of a surface are paths along which the values of z = f (x,y) are constant;

Level Curves One of the most useful and common methods for visualizing functions (or surfaces) of two varibles is a Contour Map in which points of constant elevation are joined in a 2D plane to form level curves (or contour curves )Ie the level curves of a function are simply the traces of that function in various planes z = a, projected onto the xy plane The example shown below is the surface Examine the level curves of the function EDITED 0740 GMT2 I replaced all occurrences of contour lines by level curves and added definition of a saddle point multivariablecalculus contourintegration algebraiccurves implicitfunctiontheorem

Intersecting lines on contour plots are level curves around saddle points of negative Gauss curvature surfaces There are two directions that are horizontal, roughly asymptotic, depending on how the cutting plane is aspect ed to the topography How do the lines indicate which side of the mountain is the steepest?This is why Contour lines (sometime named level curves) are often used to display 2D functions on a flat image plane For instance geographic maps often use level curves to display the elevation In a map z is the terrain elevation and ( x, y) your location Every points which belong to the same curve have the same height, ie the same zSee the latter for their interpretation The appearance of contour lines can be defined with a line style style in the same manner as plot Only line style and color are used;

Level curves and contour plots are another way of visualizing functions of two variables If you have seen a topographic map then you have seen a contour plot Example To illustrate this we first draw the graph of z = x2 y2 On this graph we draw contours, which are curves at a fixed height z = constant For example the curve at height z = 1 is the circle x2 y2 = 1 On the graph we have I am trying to plot contour lines of pressure level I am using a netCDF file which contain the higher resolution data (ranges from 3 km to 27 km) Due to higher resolution data set, I get lot of pressure values which are not required to be plotted (rather I don't mind omitting certain contour line of insignificant values) An alternative method to representing multivariable functions with a twodimensional input and a onedimensional output, contour maps involve drawing purely in the input space Created by Grant Sanderson Visualizing scalarvalued functions Representing points in 3d Introduction to 3d graphs

For each $c$, this is a line with slope $A/B$ and $y$intercept $y = (DCc)/B$ Since the slope does not depend on $c$, the level curves are parallel lines, and as $c$ runs over equally spaced values these lines will be a constant distance apart Consequently, the contour map of a plane consists of equally spaced parallel lines Contour lines are imaginary lines that connect places at the same height above sea level These are recorded in brown on the survey maps These documents appear to be closed curves The height difference between the two adjacent contour lines on the survey map is m This is called contour interval As the distance between the contour lines on the map increases,Contour Lines of {eq}F(x,y) {/eq} All the level curves sketched above are lines passing through the origin, one with a negative slope ({eq}m=1 {/eq}) and the other two with a positive slope

The graph above may have reminded you of something – a contour (or topographical) map of a landscape Essentially the level sets are the contour lines on a map of a surfaceThen the projection of the set of level curves of $f$ onto the $xy$plane is called the Contour Plot or Contour Map of $f$ When we depict a contour plot of a two variable function, it is important to note that it is impossibly to place all the level curves of $z = f(x, y)$ onto the $xy$ plane, and so we often choose specific level curvesIn other words, these commands both produce a set of level curves of the input function for a discrete set of values (ie levels) of the third coordinate The differences are as follows contourplot3d generates a 3D view of the contours raised to their appropriate levels, whereas contourplot generates a flat 2D contour
