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 (a_{n}, b_{n}).

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)**
enter `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**.
