Extends: anychart.scales.Base

Base for all scatter scales (Linear, Logarithmic and DateTime). Doesn't declare any ticks, so different scales can declare their own.

Methods Overview

Specific settings
extendDataRange()Extends the current input domain with the passed values (if such don't exist in the domain).
finishAutoCalc()Informs the scale that an auto range calculation started for the chart in past was ended.
inverseTransform()Returns tick by its position ratio.
inverted()Inversion state.
maxTicksCount()Maximum ticks count.
maximum()Scale maximum.
minimum()Scale minimum.
startAutoCalc()Informs scale that an auto range calculation started for the chart, so it should reset its data range on the first
transform()Returns tick position ratio by its name.
Events
listen()Adds an event listener.
listenOnce()Adds a single time event listener.
removeAllListeners()Removes all listeners.
unlisten()Removes the listener.
unlistenByKey()Removes the listener by the key.

Methods Description

extendDataRange

Extends the current input domain with the passed values (if such don't exist in the domain).
Note: Attention! anychart.scales.Base#finishAutoCalc drops all passed values.

Params:

Name Type Description
var_args * Values that are supposed to extend the input domain.

Returns:

anychart.scales.ScatterBase - Self instance for method chaining.

Try it:

finishAutoCalc

Informs the scale that an auto range calculation started for the chart in past was ended.

Params:

Name Type Description
silently boolean If this flag is set, do not dispatch an event if reapplication needed.

Returns:

boolean - If the calculation changed the scale and it needs to be reapplied.

inverseTransform

Returns tick by its position ratio.
Note: returns correct values only after anychart.scales.Base#finishAutoCalc or chart.draw().

Params:

Name Type Description
ratio number Value to transform in input scope.

Returns:

* - Value transformed to output scope.

Try it:

inverted

Getter for scale inversion.

Returns:

boolean - Current inversion state.
Setter for scale inversion. If the scale is inverted, axes and series go upside-down or right-to-left instead of bottom-to-top and left-to-right.

Params:

Name Type Default Description
value boolean
false
Value to set.

Returns:

anychart.scales.Base - Self instance for method chaining.

Try it:

listen

Adds an event listener to an implementing object.

Params:

Name Type Default Description
type string
The event type id.
listener function
Callback method. Function that looks like function(event){ // event.actualTarget - actual event target // event.currentTarget - current event target // event.iterator - event iterator // event.originalEvent - original event // event.point - event point // event.pointIndex - event point index }.
useCapture boolean
false
Whether to fire in capture phase. Learn more about capturing https://javascript.info/bubbling-and-capturing
listenerScope Object
Object in whose scope to call the listener.

Returns:

Object - Unique key for the listener.

Try it:

listenOnce

Adds an event listener to an implementing object.

Params:

Name Type Default Description
type string
The event type id.
listener function
Callback method.
useCapture boolean
false
Whether to fire in capture phase. Learn more about capturing https://javascript.info/bubbling-and-capturing
listenerScope Object
Object in whose scope to call the listener.

Returns:

Object - Unique key for the listener.

Try it:

maxTicksCount

Getter for maximum ticks count.

Returns:

number - Maximum ticks count.
See listing
var maxTicksCount = scale.maxTicksCount();
Setter for maximum ticks count.

Params:

Name Type Default Description
value number
1000
Value to set.

Returns:

anychart.scales.ScatterBase - Self instance for method chaining.

Try it:

maximum

Getter for the current scale maximum.

Returns:

number - Current scale maximum.
Setter for scale maximum.

Params:

Name Type Default Description
value number
null
Value to set.

Returns:

anychart.scales.ScatterBase - Self instance for method chaining.

Try it:

minimum

Getter for the current scale minimum.

Returns:

number - Current scale minimum.
Setter for scale minimum.

Params:

Name Type Default Description
value number
null
Value to set.

Returns:

anychart.scales.ScatterBase - Self instance for method chaining.

Try it:

removeAllListeners

Removes all listeners from an object. You can also optionally remove listeners of some particular type.

Params:

Name Type Description
type string Type of event to remove, default is to remove all types.

Returns:

number - Number of listeners removed.

Try it:

startAutoCalc

Informs scale that an auto range calculation started for the chart, so it should reset its data range on the first call of this method if needed.

Returns:

anychart.scales.Base - Chaining.

transform

Returns tick position ratio by its name.
Note: returns correct values only after anychart.scales.Base#finishAutoCalc or chart.draw().

Params:

Name Type Description
value * Value to transform in input scope.

Returns:

number - Value transformed to scope [0, 1].

Try it:

unlisten

Removes a listener added using listen() or listenOnce() methods.

Params:

Name Type Default Description
type string
The event type id.
listener function
Callback method.
useCapture boolean
false
Whether to fire in capture phase. Learn more about capturing https://javascript.info/bubbling-and-capturing
listenerScope Object
Object in whose scope to call the listener.

Returns:

boolean - Whether any listener was removed.

Try it:

unlistenByKey

Removes an event listener which was added with listen() by the key returned by listen() or listenOnce().

Params:

Name Type Description
key Object The key returned by listen() or listenOnce().

Returns:

boolean - Whether any listener was removed.
