Scatter Line Plot Type Attributes Object

NOTE: Items in bold red represent patches that may or may not be added to OFC-2.

The “scatter_line” plot type is used to plot a series of points with a line drawn between each point.

It can optionally color fill an area defined by the series of points. The “base” for the area can be defined as a Y line, an X line or a point (X,Y).

{"type":”scatter_line”, "text":”Scatter Line with Area”,

“tip”: “[#x#,#y#] #size#”,

“width”: 2, “colour”: “#d01f3c”, “dot-size”: 5,

“area-style”:{“colour”:”#b0101c”, ”alpha”:0.5, ”y”:0 },

"dot-style": { "type":"anchor", "sides":5, "hollow":true,

"background-colour":"#104a80", "background-alpha": 0.4,

"width":1, “on-click”:”http://www.google.com” },

“values”: [ {“x”:1,“y”:1}, {“x”:2,“y”:2}, {“x”:3,“y”:4, “on-click”:”http://yahoo.com”} ] }

Definition of the the “area-style” object within the “scatter_line” type element object. If this object is defined then the area between the plot and the defined area base is coloured in. The base for the area to be filled can be an X line, a Y line or an (X,Y) point.

OBJECT	ATTRIBUTE	VALID VALUES	DEFAULT	NOTES
“area-style”
	“colour”	“#RRGGBB” hex string undefined	undefined	Color for area “under” the plot. Undefined causes the area to be colored the same as the plot's color.
	“alpha”	Real number 0 to 1	1	Specifies the opacity of the color filled area. Ranges from 0 (transparent) to 1 (totally opaque).
	“x”	Any number undefined	undefined	Specifies the X component for the base of the filled area. If the Y component is not defined then the base will be a vertical line at the value X; otherwise, the base will be the point (X, Y).
	“y”	Any number undefined	undefined	Specifies the Y component for the base of the filled area. If the X component is not defined then the base will be a horizontal line at the value Y; otherwise, the base will be the point (X, Y).

Definition of the the “dot-style” object within the “scatter_line” type element object. If this object is defined then the points of the line will be drawn with the defined characteristics. Values in this object override values defined at the plot level.

OBJECT	ATTRIBUTE	VALID VALUES	DEFAULT	NOTES
“dot-style”
	“type”	“point” “dot” “star” “bow” “anchor”	“point”	point = a hollow circle dot = a filled circle star = a 5 pointed star bow = a bow tie anchor = a 3 to n sided object
	“alpha”	Real number 0 to 1	1	Specifies the opacity of the line for the anchor, bow and star
	“hollow”	true or false	false	Specifies whether the anchor should have a the center filled with the background-colour
	“background-colour”	“#RRGGBB” hex string	undefined	Specifies the fill color for a hollow anchor
	“background-alpha”	Real number 0 to 1	1	Specifies the opacity of the fill color for a hollow anchor
	“dot-size”	0 to n	5	Defines the radius in pixels of the circle for the points. Anchors fit inside the circle.
	“tip”	“ToolTip text”	*See notes	Specifies the text to display in the pop up tool tip. * Default is “[#x#,#y#] #size#” which displays the X, Y and dot-size values.
	“halo-size”	0 to n	0	Number of pixels around the anchor to erase forming a gap between the anchor and the line coming in to it.
	“rotation”	-180 to 180	0	Specifies degrees of rotation to apply to the anchor.
	“sides”	3 to 360	3	Number of sides of an “anchor” type
	“width”	0 to n	2	Width of the line drawn for the anchor. 0 is a hairline.
	“on-click”	user defined text	undefined	Function or URL to invoke when the point is clicked on

Definition of the “values” array of point objects within the “scatter_line” type element object. Any of the values in the “dot-style” can be overridden here as well.

OBJECT	ATTRIBUTE	VALID VALUES	DEFAULT	NOTES
				This table defines point objects within the “values” array for a scatter_line element object
	“x”	Any number null	-1	Specifies the X component for the point. If null is specified then the point will not be visible and it will generate a gap in the line. The line will pick up again with the next point.
	“y”	Any number	-1	Specifies the Y component for the point.
	“type”	“point” “dot” “star” “bow” “anchor”	“point”	point = a hollow circle dot = a filled circle star = a 5 pointed star bow = a bow tie anchor = a 3 to n sided object
	“alpha”	Real number 0 to 1	1	Specifies the opacity of the line for the anchor, bow and star
	“hollow”	true or false	false	Specifies whether the anchor should have a the center filled with the background-colour
	“background-colour”	“#RRGGBB” hex string	undefined	Specifies the fill color for a hollow anchor
	“background-alpha”	Real number 0 to 1	1	Specifies the opacity of the fill color for a hollow anchor
	“dot-size”	0 to n	5	Defines the radius in pixels of the circle for the points. Anchors fit inside the circle.
	“tip”	“ToolTip text”	*See notes	Specifies the text to display in the pop up tool tip. * Default is “[#x#,#y#] #size#” which displays the X, Y and dot-size values.
	“halo-size”	0 to n	0	Number of pixels around the anchor to erase forming a gap between the anchor and the line coming in to it.
