ContourPlot
 Usage
• ContourPlot[f, {x,  ,  }, {y,  ,  }] generates a contour plot of f as a function of x and y.
Notes
• ContourPlot evaluates its arguments in a non-standard way (see Section A.4.2). You should use Evaluate to evaluate the function to be plotted if this can safely be done before specific numerical values are supplied. • ContourPlot by default generates grayscale output, in which larger values are shown lighter. • At positions where f does not evaluate to a real number, holes are left so that the background to the contour plot shows through. • ContourPlot has the same options as ContourGraphics, with the following additions:
| Compiled | True | whether to compile the function to plot | | PlotPoints | 25 | the number of points in each direction at which to sample the function |
• ContourPlot has the default option setting Frame -> True. • ContourPlot returns a ContourGraphics object, with the MeshRange option set. • New in Version 1.
