gc:**fillArc** is a function that is part of gc (Graphics Context).

Draws a color-filled arc in the rectangle with upper left corner (x,y) and pixel *width* and *height*. The arc is drawn beginning at *startAngle* degrees and ending at *endAngle*.

Zero degrees points to the right and 90 degrees points up (standard mathematical practice but worth mentioning since the y axis is inverted).

This has been introduced in TI-Nspire OS 3.0 (*Changes*).

## Syntax

gc:**fillArc**(x, y, width, height, start angle, finish angle)

Parameter | Type | Description |
---|---|---|

number | The x-coordinate of the upper-left point | |

number | The x-coordinate of the upper-left point | |

number | Width of the rectangle containing the arc | |

number | Height of the rectangle containing the arc | |

number | start angle | |

number | finish angle |

## Example

`gc:fillArc(10, 10, 20, 30, 0, 120)`

## Good to know

To draw a circle, the width and height must be equal length and the start and end angles must be 0 and 360. If width and height are different lengths, this routine will draw an oval.
