Explore our point grapher, a versatile coordinates plotter that creates point graphs and line graphs in Cartesian (rectangular and oblique) and polar coordinate systems.
A points grapher, also known as coordinates grapher, is a grapher that plots a set of points in a coordinate system, where the coordinates of the points are given by ordered pairs (an, bn).
The coordinates or components of the points can be Cartesian coordinates or polar coordinates.
Our online point grapher is a powerful coordinates plotter that lets you easily plot points and create a point graph or line graph in Cartesian and polar coordinate systems.
Our online coordinates grapher is the only coordinates plotter that allows you to rotate axes, graph points, and create line graphs in oblique coordinate systems, where the axes can be rotated to any angle and have any orientation.
To use our point grapher, simply enter the coordinates of each point, separated by a comma, and separate the points by semicolons. For example, to plot points (1, 2) and (3, 4)
1,2; 3,4; (note that parentheses are excluded). You can even use numeric expressions, such as
2/3 + sin(pi/3), for the components of a point.
When graphing points in polar coordinates, our online polar point grapher, enables you to input angular coordinates in various units, including radians, degrees, and grades.
- pi is replaced by π.
