[[Image:Cartesian coordinate surfaces.png|thumb|240px|right| The [[Coordinate system#Coordinate surface|coordinate surfaces]] of the Cartesian coordinates (''x'', ''y'', ''z''). The ''z''-axis is vertical and the ''x''-axis is highlighted in green. Thus, the red plane shows the points with ''x''=1, the blue plane shows the points with ''z''=1, and the yellow plane shows the points with ''y''=-1. The three surfaces intersect at the point '''P''' (shown as a black sphere) with the Cartesian coordinates (1, -1, 1).]]
