# What is a 2d contour plot?

## What is a 2d contour plot?

A contour plot is a graphical technique for representing a 3-dimensional surface by plotting constant z slices, called contours, on a 2-dimensional format. That is, given a value for z, lines are drawn for connecting the (x,y) coordinates where that z value occurs.

### What does a contour plot tell you?

Contour plots (sometimes called Level Plots) are a way to show a three-dimensional surface on a two-dimensional plane. It graphs two predictor variables X Y on the y-axis and a response variable Z as contours. These contours are sometimes called z-slices or iso-response values.

#### What is contour plot in Ansys?

ANSYS FLUENT allows you to plot contour lines or profiles superimposed on the physical domain. Contour lines are lines of constant magnitude for a selected variable (isotherms, isobars, etc.).

How do you read a 2d contour plot?

How to interpret contour plot?

1. Contour plots can indicate peaks or valleys within the range of X and Y at the center of concentric shapes.
2. If the contour lines are spaced close to each other, then the values change rapidly while if the contour lines are spaced far apart then the z values change more slower.

How do you find the contour plot?

Contour lines, or level curves, are obtained from a surface by slicing it with horizontal planes. A contour is obtained by slicing the surface with a horizontal plane with equation z = c. Thus, the equation for the contour at height c is given by: f(x,y) = c.
