## POLAR CHART

## Background

The Polar Chart is a two-dimensional display of the independent variable on the angular axis and the dependent variable on the radial axis. The origin is at the center of the circle by default. By showing trends in values based on angles, polar charts are very useful for engineers and mathematicians.

For references: Brief Description of Polar Charts, In Depth Description, Difference Examples.

## Description

Go to the SOCR Charts and select Miscellaneous from the items located on the left, then select Polar Chart Demo:

Note that in this demonstration, the origin is set for a specific value. The radial axis is labeled as angles since it represent values of the dependent variable, and the horizontal axis represents independent variables. There are two graphs on the Polar Chart, one red and the other blue. All the values in both graphs are connected and form four sided shapes. Below the graph displays numerical values of the graphs separately.

## Applications

One of the most persuasive elements when proposing data and literature to others is a well-designed chart presentation.

Engineers may often use this application for their measurements and research of engines or machinery.

Mathematicians or physicists may use this application in their research of mapping the universe or analysis and experiments.
