patternColor(colorArray, height[, startX, startY])

Create a pattern color using an array of colors as the bitmap pattern.

A pattern color is a dynamic color that changes according to a 2D periodic pattern. When it is used to fill an area, the area will look like being tiled with a wallpaper pattern.

Argument	Default	Description
colorArray	(Mandatory)	An array of colors representing the colors of the bitmap pixels. The color of the pixel at (x, y) should correspond to index (x + y * width - 1) of the array.
height	(Mandatory)	The height of the bitmap in pixels. (The width is automatically computed as the size of the color array divided by the height.)
startX	0	The x cooridinate of a reference point to align with the top-left corner the pattern.
startY	0	The y cooridinate of a reference point to align with the top-left corner the pattern.

Return a 32-bit integer acting as a handle to the pattern color. The handle can be used in any ChartDirector API that expects a color as an argument.
