infchart.lines holds the styles to be used for the lines as they are
drawn, in rotation order.  The constructor sets up three styles: red,
green, and blue.  If you never add any additional styles to it, then
there will always be three.  Lines 0, 1, 2, 3, 4 will be drawn with
style 0, 1, 2, 0, 1, respectively, from infchart.lines.

If you want to increase the number of styles in the rotation, just add
them yourself:
    infchart.lines[4].strokeColor = colors.purple
