Draws contours of a 2-variable function.
ContourPlot[f, {x, xmin, xmax}, {y, ymin, ymax}]
ContourPlot[f == g, {x, xmin, xmax}, {y, ymin, ymax}]
ContourPlot[{f1 == g1, f2 == g2, …}, {x, xmin, xmax}, {y, ymin, ymax}]
ContourPlot[…, {x, y}∈ reg]
Head[ContourPlot[x^2 + y^2, {x, -1, 1}, {y, -1, 1}]]
→ GraphicsHead[ContourPlot[Sin[x] Sin[y], {x, -3, 3}, {y, -3, 3}, Contours -> {-0.5, 0, 0.5}, ContourShading -> False]]
→ Graphics- Contours — an integer (number of contours) or a list of levels.
- ContourStyle — directives applied to the contour lines.
- ContourShading — True / False / Automatic.
- ColorFunction — color map for the shaded regions.
- PlotPoints / MaxRecursion — sampling control.
