Create a new fillstyle to fill the object with Colors based on value. The color for the data-point would be selected from a specified LUT, which contains the information about gradient steps.
Create the paletted fillstyle with specified LUT lookup table.
Example:
// create LUT from 0..100 with gradient steps.
const lut = new LUT( {
steps: [
{ value: 0, color: ColorRGBA( 0, 0, 0 ) },
{ value: 30, color: ColorRGBA( 255, 255, 0 ) },
{ value: 45, color: ColorRGBA( 255, 204, 0 ) },
{ value: 60, color: ColorRGBA( 255, 128, 0 ) },
{ value: 100, color: ColorRGBA( 255, 0, 0 ) }
],
interpolate: true
} )
// create fillstyle with attached lookup table
const palettedfill = new PalettedFill({ lut })
Optional object containing parameters for creation of fillstyle.
Get automatically computed highlight style.
FillStyle object
Get LUT lookup table.
LUT object.
Unlike other types in Immutable.js, the Record()
function creates a new
Record Factory, which is a function that creates Record instances.
See above for examples of using Record()
.
Note: Record
is a factory function and not a class, and does not use the
new
keyword during construction.
Records allow passing a second parameter to supply a descriptive name that appears when converting a Record to a string or in any error messages. A descriptive name for any record can be accessed by using this method. If one was not provided, the string "Record" is returned.
const { Record } = require('immutable')
const Person = Record({
name: null
}, 'Person')
var me = Person({ name: 'My Name' })
me.toString() // "Person { "name": "My Name" }"
Record.getDescriptiveName(me) // "Person"
True if maybeRecord
is an instance of a Record.
Fillstyle class to colorize the data based on value using LUT lookup table.
LUT class stores information about values and its associated colors, which provides efficient lookup of the color based on provided value as well as linear and step interpolation between colors.
ChartXY - LineSeries and PointSeries: When this fillstyle is set, the Series will colorize the data-Points based on X / Y value.
Instances of PalettedFill are immutable, meaning that its setters don't modify the object, but instead return a completely new modified object.
