How to fix Long Method Complexity

/* Flot plugin for rendering pie charts.

Copyright (c) 2007-2014 IOLA and Ole Laursen.
Licensed under the MIT license.

The plugin assumes that each series has a single data value, and that each
value is a positive integer or zero.  Negative numbers don't make sense for a
pie chart, and have unpredictable results.  The values do NOT need to be
passed in as percentages; the plugin will calculate the total and per-slice
percentages internally.

* Created by Brian Medendorp

* Updated with contributions from btburnett3, Anthony Aragues and Xavi Ivars

The plugin supports these options:

	series: {
		pie: {
			show: true/false
			radius: 0-1 for percentage of fullsize, or a specified pixel length, or 'auto'
			innerRadius: 0-1 for percentage of fullsize or a specified pixel length, for creating a donut effect
			startAngle: 0-2 factor of PI used for starting angle (in radians) i.e 3/2 starts at the top, 0 and 2 have the same result
			tilt: 0-1 for percentage to tilt the pie, where 1 is no tilt, and 0 is completely flat (nothing will show)
			offset: {
				top: integer value to move the pie up or down
				left: integer value to move the pie left or right, or 'auto'
			},
			stroke: {
				color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#FFF')
				width: integer pixel width of the stroke
			},
			label: {
				show: true/false, or 'auto'
				formatter:  a user-defined function that modifies the text/style of the label text
				radius: 0-1 for percentage of fullsize, or a specified pixel length
				background: {
					color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#000')
					opacity: 0-1
				},
				threshold: 0-1 for the percentage value at which to hide labels (if they're too small)
			},
			combine: {
				threshold: 0-1 for the percentage value at which to combine slices (if they're too small)
				color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#CCC'), if null, the plugin will automatically use the color of the first slice to be combined
				label: any text value of what the combined slice should be labeled
			}
			highlight: {
				opacity: 0-1
			}
		}
	}

			// When combining smaller slices into an 'other' slice, we need to
			// add a new series.  Since Flot gives plugins no way to modify the
			// list of series, the pie plugin uses a hack where the first call
			// to processDatapoints results in a call to setData with the new
			// list of series, then subsequent processDatapoints do nothing.

			// The plugin-global 'processed' flag is used to control this hack;
			// it starts out false, and is set to true after the first call to
			// processDatapoints.

			// Unfortunately this turns future setData calls into no-ops; they
			// call processDatapoints, the flag is true, and nothing happens.

			// To fix this we'll set the flag back to false here in draw, when
			// all series have been processed, so the next sequence of calls to
			// processDatapoints once again starts out with a slice-combine.
			// This is really a hack; in 0.9 we need to give plugins a proper
