BaseChart.radialGradientColor2

Usage

radialGradientColor2(cx, cy, rx, ry, colorArray [, periodic ])

Description

Creates a multi-point radial gradient color.

In this method, the color points are defined as an array of radial distances and colors, in the following format:

The distances are specified as a number from 0 - 256 (0 - 100 in hex), in which 0 represents the center of the gradient defining ellipse, and 256 (100 in hex) represents the perimeter of the gradient defining ellipse.

For example, the array (in hex):

means the center (000000) is red (FF0000), the mid-point (000080 in hex) is yellow (FFFF00), and the perimeter (000100 in hex) is green (00FF00).

In this method, the color points are defined as an array of radial distances and colors, in the following format:

distance0, color0, distance1, color1, .... distanceN, colorN

The distances are specified as a number from 0 - 256 (0 - 100 in hex), in which 0 represents the center of the gradient defining ellipse, and 256 (100 in hex) represents the perimeter of the gradient defining ellipse.

For example, the array (in hex):

000000, FF0000, 000080, FFFF00, 000100, 00FF00

means the center (000000) is red (FF0000), the mid-point (000080 in hex) is yellow (FFFF00), and the perimeter (000100 in hex) is green (00FF00).

Arguments

Argument | Default | Description |
---|---|---|

cx | (Mandatory) | The x coordinate of the center of the radial gradient. |

cy | (Mandatory) | The y coordinate of the center of the radial gradient. |

rx | (Mandatory) | The horizontal radius of the radial gradient defining ellipse. |

ry | (Mandatory) | The vertical radius of the radial gradient defining ellipse. |

colorArray | (Mandatory) | An array defining the radial distances and colors. |

periodic | false | Specifies whether the gradient will repeat itself periodically. If the gradient does not repeat itself, the points that lie outside the gradient defining ellipse will assume the color at the perimeter of the gradient defining ellipse. |

Return Value

A 32-bit integer representing the radial gradient color.
