new ColorManager()
Typically, only a single ColorManager is required by the visualization and that
is best acquired via Oracle.BDD.Portlets.Visualization.Renderers.BaseRenderer#getColorManager.
However, multiple instances of a ColorManager may be created.
var dayOfWeekColorMgr = new Oracle.BDD.Portlets.Visualization.Util.ColorManager({
library: ["#6B486B", "#718BAE", "#ABBE23"],
scaleDomain: ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"]
});

Methods
getColor(domainKey) → {string}
Returns the hex value from the color library corresponding to the domain key.
See D3 Ordinal Scales
for more information on color scales and scale domains.
Parameters:
| Name | Type | Description |
|---|---|---|
domainKey |
string | Numeric | The domain key |
- Source:
Returns:
Hex value of color
- Type
- string
getScaleDomain() → {Array.<string>}
Returns the scale's input domain values.
See D3 Ordinal Scales
for more information on color scales and scale domains.
- Source:
Returns:
The array of domain values
- Type
- Array.<string>
setLibrary(colors)
Sets the color library for the color scale of the visualization. Value passed may be an array
of hex strings or a string value of '10', '20' or '20b' to set the color library to that of
the D3 category10, category20 or category20b libraries respectively.
See {@link https://github.com/mbostock/d3/wiki/Ordinal-Scales#categorical-colors|Categorical Colors} for information on D3 categorical color libraries.
See D3 Ordinal Scales for more information on color scales and scale domains.
Parameters:
| Name | Type | Description |
|---|---|---|
colors |
Array.<Object> | string | An array of hex values to serve as the color library for the color scale. The string values of '10', '20' or '20b' may be passed to set the color library to those of the D3 category10, category20 or category20b libraries |
- Source:
setScaleDomain(domain)
Sets the color scale's input domain values. This is the means to ensure that any instance
of the ColorManager configured with the same library will return the same color for the given
key value (getColor(domainKey)). Setting a scale domain is optional; one instance of the ColorManager
will always return the same value for the same input key. Setting a scale domain ensures consistency
across multiple instances of the ColorManager (i.e. from page request to page request).
See D3 Ordinal Scales for more information on color scales and scale domains.
Parameters:
| Name | Type | Description |
|---|---|---|
domain |
Array.<Object> | An array of values to serve as the color scale's domain input values |
