How do you find the contour plot of a function?

If we have a formula for a function z = f(x y) then we can find the equations for the contours easily. Each contour is obtained by slicing the surface with the horizontal plane z = c so the equation for the contour at height c is simply f(x y) = c. (b) f(x y) = cos√x2 + y2.

What is a contour map of a function?

More generally a contour line for a function of two variables is a curve connecting points where the function has the same particular value. … A contour map is a map illustrated with contour lines for example a topographic map which thus shows valleys and hills and the steepness or gentleness of slopes.

How do you analyze contour plots?

Use a contour plot to see how a response variable relates to two predictor variables.

A contour plot contains the following elements:
  1. Predictors on the x- and y-axes.
  2. Contour lines that connect points that have the same response value.
  3. Colored contour bands that represent ranges of the response values.

How do you do a water table contour map?

Map Setup. Write the value of each water elevation next to the respective measurement location typically at a well on the scaled map. Draw the first line between the highest and lowest elevation points. Identify convenient round-number values between the high and low points through which you will draw the contours.

How do you smooth a contour plot in origin?

In order to smooth the lines in a contour plot you need to smooth the data in the matrix it is plotted from. Do this by using the Analysis: Signal Process: Smooth from the Origin menu. This will perform a smoothing routine on your data and the associated contour plot will become smooth with the new values.
