	var __AxisCtorArgs = {
		// summary:
		//		Optional arguments used in the definition of an axis.
		// vertical: Boolean?
		//		A flag that says whether an axis is vertical (i.e. y axis) or horizontal. Default is false (horizontal).
		// fixUpper: String?
		//		Align the greatest value on the axis with the specified tick level. Options are "major", "minor", "micro", or "none".  Defaults to "none".
		// fixLower: String?
		//		Align the smallest value on the axis with the specified tick level. Options are "major", "minor", "micro", or "none".  Defaults to "none".
		// natural: Boolean?
		//		Ensure tick marks are made on "natural" numbers. Defaults to false.
		// leftBottom: Boolean?
		//		The position of a vertical axis; if true, will be placed against the left-bottom corner of the chart.  Defaults to true.
		// includeZero: Boolean?
		//		Include 0 on the axis rendering.  Default is false.
		// fixed: Boolean?
		//		Force all axis labels to be fixed numbers.  Default is true.
		// majorLabels: Boolean?
		//		Flag to draw labels at major ticks. Default is true.
		// minorTicks: Boolean?
		//		Flag to draw minor ticks on an axis.  Default is true.
		// minorLabels: Boolean?
		//		Flag to labels on minor ticks when there is enough space. Default is true.
		// microTicks: Boolean?
		//		Flag to draw micro ticks on an axis. Default is false.
		// htmlLabels: Boolean?
		//		Flag to use HTML (as opposed to the native vector graphics engine) to draw labels. Default is true.
		// min: Number?
		//		The smallest value on an axis. Default is 0.
		// max: Number?
		//		The largest value on an axis. Default is 1.
		// from: Number?
		//		Force the chart to render data visible from this value. Default is 0.
		// to: Number?
		//		Force the chart to render data visible to this value. Default is 1.
		// majorTickStep: Number?
		//		The amount to skip before a major tick is drawn. When not set the major ticks step is computed from
		//		the data range.
		// minorTickStep: Number?
		//		The amount to skip before a minor tick is drawn. When not set the minor ticks step is computed from
		//		the data range.
		// microTickStep: Number?
		//		The amount to skip before a micro tick is drawn. When not set the micro ticks step is computed from
		// labels: Object[]?
		//		An array of labels for major ticks, with corresponding numeric values, ordered by value.
		// labelFunc: Function?
		//		An optional function to use to compute label text. It takes precedence over
		//		the default text when available. The function must be of the following form:
		//	|		function labelFunc(text, value, precision) {}
		//		`text` is the already pre-formatted text. Pre-formatting is done using `dojo/number` is available, `Date.toFixed` otherwise.
		//		`value`  is the raw axis value.
		//		`precision` is the requested precision to be applied.
		// maxLabelSize: Number?
		//		The maximum size, in pixels, for a label.  To be used with the optional label function.
		// stroke: dojox.gfx.Stroke?
		//		An optional stroke to be used for drawing an axis.
		// majorTick: Object?
		//		An object containing a dojox.gfx.Stroke, and a length (number) for a major tick.
		// minorTick: Object?
		//		An object containing a dojox.gfx.Stroke, and a length (number) for a minor tick.
		// microTick: Object?
		//		An object containing a dojox.gfx.Stroke, and a length (number) for a micro tick.
		// tick: Object?
		//		An object containing a dojox.gfx.Stroke, and a length (number) for a tick.
		// font: String?
		//		An optional font definition (as used in the CSS font property) for labels.
		// fontColor: String|dojo.Color?
		//		An optional color to be used in drawing labels.
		// titleGap: Number?
		//		An optional grap between axis title and axis label
		// titleFont: String?
		//		An optional font definition for axis title
		// titleFontColor: String?
		//		An optional axis title color
		// titleOrientation: String?
		//		An optional orientation for axis title. "axis" means the title facing the axis, "away" means facing away.
		//		If no value is set "axis" is used.
		// enableCache: Boolean?
		//		Whether the ticks and labels are cached from one rendering to another. This improves the rendering performance of
		//		successive rendering but penalize the first rendering. For labels it is only working with gfx labels
		//		not html ones.  Default false.
		// dropLabels: Boolean?
		//		Whether the axis automatically drops labels at regular interval or not to avoid labels overlapping.
		//		This gives better results but require more computations.  You can disable it to save computation
		//		time when you know your labels won't overlap. Default is true.
		// labelSizeChange: Boolean?
		//		Indicates to the axis whether the axis labels are changing their size on zoom. If false this allows to
		//		optimize the axis by avoiding recomputing labels maximum size on zoom actions. Default is false.
