Extends: anychart.scales.ScatterBase

The DateTime class contains methods for configuring DateTime scale.
Note: To create instance use anychart.scales#dateTime method.

Methods Overview

Specific settings
alignMaximum()Align maximum settings.
alignMinimum()Align minimum settings.
finishAutoCalc()Informs the scale that an auto-range calculation started for the chart in past was ended.
getType()Returns scale type.
inverseTransform()Returns tick by its position ratio.
inverted()Inversion state.
maxTicksCount()Maximum ticks count.
maximum()Scale maximum.
maximumGap()Maximum gap settings.
minimum()Scale minimum.
minimumGap()Minimum gap settings.
minorTicks()Minor ticks settings.
softMaximum()Soft maximum settings.
softMinimum()Soft minimum settings.
startAutoCalc()Informs scale that an auto-range calculation started for the chart, so it should reset its data range on the first
ticks()Ticks settings.
Miscellaneous
extendDataRange()Extends the current input domain with the passed values (if such don't exist in the domain).
transform()Returns tick position ratio by its name.

Methods Description

alignMaximum

Getter for a flag if the maximum should be aligned by major ticks interval.

Returns:

boolean - Whether to enable maximum alignment by interval.
See listing
var scale = chart.xScale();
var alignMaximum = scale.alignMaximum();
Getter for a flag if the maximum should be aligned by major ticks interval.

Params:

NameTypeDefaultDescription
enabledboolean
false
Whether to enable maximum alignment by interval.

Returns:

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

alignMinimum

Setter for a flag if the minimum should be aligned by major ticks interval.

Returns:

boolean - Whether to enable minimum alignment by interval.
See listing
var scale = chart.xScale();
var alignMinimum = scale.alignMinimum();
Setter for a flag if the minimum should be aligned by major ticks interval.

Params:

NameTypeDefaultDescription
enabledboolean
false
Whether to enable minimum alignment by interval.

Returns:

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

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:

NameTypeDescription
var_args*Values that are supposed to extend the input domain.

Returns:

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

finishAutoCalc

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

Params:

NameTypeDescription
silentlybooleanIf 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.

getType

Returns scale type.

Returns:

string - Scale type.

inverseTransform

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

Params:

NameTypeDescription
rationumberValue to transform in input scope.

Returns:

* - Value transformed to output scope.

inverted

Getter for the scale inversion.

Returns:

boolean - The 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:

NameTypeDefaultDescription
enabledboolean
false
Inverted state to set.

Returns:

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

maxTicksCount

Getter for the maximum ticks count.

Returns:

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

Params:

NameTypeDefaultDescription
countnumber
1000
Maximum ticks count to set.

Returns:

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

maximum

Getter for the scale maximum.

Returns:

number - Scale maximum.
See listing
var scale = chart.yScale();
var maximum = scale.maximum();
Setter for the scale maximum.

Params:

NameTypeDefaultDescription
maximumnumber
null
Maximum value to set.

Returns:

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

maximumGap

Getter for the scale maximum gap.

Returns:

number - The scale maximum gap.
Setter for the scale maximum gap.

Params:

gapnumber
0.1
Gap value from 0 to 1.

Returns:

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

minimum

Getter for the scale minimum.

See listing
var scale = chart.yScale();
var minimum = scale.minimum();
Setter for the scale minimum.

Params:

NameTypeDefaultDescription
minimumnumber
null
Scale minimum to set.

Returns:

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

minimumGap

Params:

NameTypeDefaultDescription
gapnumber
0.1
Gap value from 0 to 1.

Returns:

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

minorTicks
