ERROR BARS
Description:
In Polar Charts, a series is represented by a closed curve that connects points in the polar coordinate system.
Each data point is determined by the distance from the pole (the radial coordinate) and the angle from the fixed direction (the angular coordinate).
- Graphing a point with polar coordinates (r, θ).
- In polar coordinates, the dependent variable, r, gives not a height but a distance from the pole in direction θ.
- When graphing an equation in polar coordinates, we think of sweeping around the pole in the counterclockwise direction, and at each angle θ, the r-value tells us how far the graph is from the pole.
Example
| A | B | C |
| X | Y | Error |
| 1.6 | 1.97 | 0.897 |
| 2.51 | 3.1 | 0.732 |
| 3.55 | 2.79 | 0.633 |
| 3.83 | 3.96 | 0.6 |
| 5.47 | 4.4 | 0.633 |
| 5.77 | 5.72 | 0.732 |
| 6.89 | 7.2 | 0.897 |
| 7.76 | 7.65 | 1.128 |
