Properties

axes ↔ dynamic

Set y axis the data related to. y and y2 can be used.

getter/setter pair

classes ↔ dynamic

Set custom data class. If this option is specified, the element g for the data has an additional class that has the prefix billboard-target- (e.g. billboard-target-additional-data1-class).

getter/setter pair

colors ↔ dynamic

Set color for each data.

getter/setter pair

columns ↔ List<List>

Load data from a multidimensional array, with each element containing an array consisting of a datum name and associated data values.

getter/setter pair

empty ↔ dynamic

Set text label to be displayed when there's no data to show.

getter/setter pair

filter ↔ bool Function(List)

getter/setter pair

groups ↔ List<List<String>>

Set groups for the data for stacking.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

headers ↔ List

XHR header value

getter/setter pair

hide ↔ dynamic

Hide each data when the chart appears. If true specified, all of data will be hidden. If multiple ids specified as an array, those will be hidden.

getter/setter pair

idConverter ↔ String Function(String)

Converts data id value

getter/setter pair

json ↔ dynamic

Parse a JSON object for data.

getter/setter pair

keys ↔ dynamic

Choose which JSON object keys correspond to desired data.

getter/setter pair

labels ↔ dynamic

Show labels on each data points or set formatter function for data labels. The formatter function receives 4 arguments such as v, id, i, j and it must return a string that will be shown as the label. The arguments are:

getter/setter pair

mimeType ↔ String

Used if loading JSON via data.url

getter/setter pair

names ↔ dynamic

Set custom data name.

getter/setter pair

onclick ← MouseEventCallback

Set a callback for click event on each data point. This callback will be called when each data point clicked and will receive d and element as the arguments.

no getter

onmax ← void Function(List<DataItem> d)

Set a callback for maximum data

no getter

onmin ← void Function(List<DataItem> d)

Set a callback for minimum data

no getter

onout ← MouseEventCallback

Set a callback for mouse/touch event on each data point. This callback will be called when mouse cursor moves out each data point and will receive d as the argument.

no getter

onover ← MouseEventCallback

Set a callback for mouse/touch over event on each data point. This callback will be called when mouse cursor or via touch moves onto each data point and will receive d as the argument.

no getter

onselected ← MouseEventCallback

Set a callback for on data selection.

no getter

onunselected ← MouseEventCallback

Set a callback for on data un-selection.

no getter

order ↔ dynamic

Define the order of the data. This option changes the order of stacking the data and pieces of pie/donut. If null specified, it will be the order the data loaded. If function specified, it will be used to sort the data and it will recieve the data as argument.

getter/setter pair

regions ↔ dynamic

Define regions for each data. The values must be an array for each data and it should include an object that has start, end, style. If start is not set, the start will be the first data point. If end is not set, the end will be the last data point. Currently this option supports only line chart and dashed style. If this option specified, the line will be dashed only in the regions.

getter/setter pair

rows ↔ List<List>

Load data from a multidimensional array, with the first element containing the data names, the following containing related data in that order.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

selection ↔ dynamic

getter/setter pair

stack ↔ dynamic

getter/setter pair

type ↔ String

Set chart type at once. If this option is specified, the type will be applied to every data. This setting can be overwritten by data.types.

getter/setter pair

types ↔ dynamic

Set chart type for each data. This setting overwrites data.type setting.

getter/setter pair

unload ↔ dynamic

getter/setter pair

url ↔ String

Load a CSV or JSON file from a URL. Note that this will not work if loading via the "file://" protocol as most browsers with block XMLHTTPRequests.

getter/setter pair

x ↔ String

Specify the key of x values in the data. We can show the data with non-index x values by th is option. This option is required when the type of x axis is timeseries. If this option is set on category axis, the values of the data on the key will be used for category names.

getter/setter pair

xFormat ↔ String

Set a format to parse string specifed as x. Default is %Y-%m-%d

getter/setter pair

xLocaltime ↔ bool

Set localtime format to parse x axis.

getter/setter pair

xs ↔ dynamic

Specify the keys of the x values for each data. This option can be used if we want to show the data that has different x values.

getter/setter pair

xSort ↔ bool

Sort on x axis.

getter/setter pair

Methods

color(String color, DataItem d) → String

Set color converter function. This option should a function and the specified function receives color (e.g. '#ff0000') and d that has data parameters like id, value, index, etc. And it must return a string that represents color (e.g. '#00ff00').

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
