Fill symbols

Simple fill symbols define the default styles applied to polygons. Each fill symbol object is defined as follows:

"defaultFillSymbols": [{
	"color": [17, 140, 17, 179],
	"type":  "esriSFS",
	"style": "esriSFSSolid", 
	"outline": { 
		"type": "esriSLS", 
		"style": "esriSLSSolid", 
		"color": [17, 140, 17, 179], 
		"width": 1.25
		}
			},
...
],

• color—Specifies the four-element array that defines the red, green, blue, and alpha values for the line, in that order. Values range from 0 through 255.
• type—Specifies the type of symbol. The type property for a simple fill symbol is esriSFS.
• style—Specifies the style applied to the fill. The default fill style is esriSFSSolid. Available fill patterns include the following:
  • esriSFSSolid
  • esriSFSCross
  • esriSFSDiagonalCross
  • esriSFSBackwardDiagonal
  • esriSFSForwardDiagonal
  • esriSFSHorizontal
  • esriSFSVertical
  • esriSFSNull (invisible)
• outline—Specifies the properties of the polygon outline. For details, see Line symbols.

Line symbols

Simple line symbols specify the default styling applied to polylines or polygon outlines. Each line symbol object is defined as follows:

],
  "defaultLineSymbols": [{
  	"color": [255, 11, 11, 255],
  	"width": 0.4,
  	"type": "esriSLS",
  	"style": "esriSLSSolid"
  },
  ...
]

• color—Specifies the four-element array that defines the red, green, blue, and alpha values for the line, in that order. Values range from 0 through 255.
• width—Specifies the width of the line, in points.
• type—Specifies the type of symbol. The type property for a simple line symbol is esriSLS.
• style—Specifies the style applied to the line. The default line style is esriSLSSolid. Available line patterns include the following:
  • esriSLSSolid
  • esriSLSDash
  • esriSLSDashDot
  • esriSLSDashDotDot
  • esriSLSDot
  • esriSLSNull (invisible)

Marker symbols

Marker symbols are used to style point features. The default marker set defines the symbols that are automatically used to represent features when point data is added to the map.

By default, Esri Maps for IBM Cognos uses simple marker symbol shapes to symbolize point data added to the map.

The defaultMarkerSymbols section of the default symbols definition file (symbols.json.txt) points to the symbols that should be used by default to symbolize points on the map. You can modify this section to point to different symbols included with Esri Maps for IBM Cognos. Each marker symbol object is defined as follows:

],
"defaultMarkerSymbols":[{ 
	"angle": 0, 
	"xoffset": 0, 
	"yoffset": 0, 
	"type": "esriSMS", 
	"style": "esriSMSCircle", 
	"color": [255, 11, 11, 128], 
	"size": 7.25, 
	"outline": 	{ 
		"color":[255,11, 11, 255], 
		"width": 1, 
		"type": "esriSLS", 
		"style": "esriSLSSolid" 
			}
				},
	...
]

• type—Specifies the type of symbol. The type property for a simple marker symbol is esriSMS. For a picture marker symbol, the type is esriPMS.
• style—Specifies the style applied to the symbol. The default symbol style is esriSMSCircle. Available symbol styles include the following:
  • esriSMSCircle
  • esriSMSCross
  • esriSMSDiamond
  • esriSMSSquare
  • esriSMSX
• color—Specifies the four-element array that defines the red, green, blue, and alpha values for the symbol, in that order. Values range from 0 through 255.
• size—Specifies the size of the symbol, in points.

Optional properties include the following:

• angle—Specifies the number of degrees (0 to 360) by which a marker symbol is rotated. Rotation occurs from east in a counterclockwise direction, where east is the 0° axis.
• xoffset—Specifies the horizontal offset, in points, of the marker symbol from the actual point location. Positive values offset to the right; negative values offset to the left.
• yoffset—Specifies the vertical offset, in points, of the marker symbol from the actual point location. Positive values offset upward; negative values offset downward.
• outline—Specifies the properties of the symbol outline. For details, see Line symbols.

The order in which the marker symbol objects are defined in the file corresponds to the order in which they are used to render features on the map as new point data is added. For example, by default, red circle shapes (esriSMSCircle) are used for the first point layer, blue circle shapes for the second layer, and so on.

Heat map color ramps

Color ramps for heat maps specify a range of colors applied to a group of symbols that represent a heat map. Each color ramp is specified as a set of colors defined as red, green, blue, and alpha values.

For example, the following JSON objects specify the colors that make up the color ramps shown below:

],
	"heatMapColorRamps": [
	[
		[0, 0, 255, 0], 
		[0, 0, 255, 0.6], 
		[0, 255, 255, 0.6], 
		[0, 255, 0, 0.6], 
		[255, 255, 0, 0.6], 
		[255, 0, 0, 0.6]
	],
	[
		[133, 193, 200, 1],
		[144, 161, 190, 1],
		[156, 129, 132, 1],
		[167, 97, 170, 1],
		[175, 73, 128, 1],
		[184, 48, 85, 1],
		[192, 24, 42, 1],
		[200, 0, 0, 1],
		[211, 51, 0, 1],
		[222, 102, 0, 1],
		[233, 153, 0, 1],
		[244, 204, 0, 1],
		[255, 255, 0, 1]
	]

Class break color ramps

Color ramps for class breaks specify a range of colors applied to features grouped into classes. The start, end, and intermediate colors that make up the color ramp are defined as objects that define the red, green, and blue values of each color (colors may also be described using hex values or named color values).

For example, the following JSON objects specify the colors that make up the color ramps shown below:

],
  "classBreaksColorRamps": [
    { "0.0": [124, 4, 4], "1.0": [247, 198, 198] },
    { "0.0": [2, 32, 227], "0.5": [0, 242, 242], "1.0": [32, 204, 16] },
    { "0.0": "#feeedf", "0.25": "#fdbe86", "0.5": "#fd8c3d", "0.75": "#e65507", "1.0": "#a63700" }
]

Unique value color ramps

Unique value color ramps specify a range of colors applied to features grouped according to unique values. The start, end, and intermediate colors that make up the color ramp are defined as objects that define the red, green, and blue values of each color (colors may also be described using hex values or named color values).

For example, the following JSON objects specify the colors that make up the color ramps shown below:

],
  "uniqueValueColorRamps": [
    { "0.0": [51, 153, 51], "0.5": [255, 255, 191], "1.0": [255, 0, 0] },
    { "0.0": [161, 215, 106], "0.5": [247, 247, 247], "1.0": [233, 163, 201] },
    { "0.0": [123, 50, 148], "0.5": [247, 247, 247], "1.0": [0, 136, 55] }
