> The format of a single series object is as follows:
'''javascript
{
color: color or number
// other stuff
}
'''
> If you don't specify color, the series will get a color from the
> auto-generated colors. The color is either a CSS color
> specification (like "rgb(255, 100, 123)") or an integer that
> specifies which of auto-generated colors to select, e.g. 0 will get
> color no. 0, etc.
