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.
Detailed description
This method allows to align the maximum value on a scale by the major interval.
If set to false, the scale bounds don't align.
If set to false, the scale bounds don't align.

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.
Detailed description
This method allows to align the minimum value on a scale by the major interval.
If set to false, the scale bounds don't align.
If set to false, the scale bounds don't align.
Params:
Name | Type | Default | Description |
---|---|---|---|
enabled | boolean | false | Whether to enable minimum alignment by interval. |
Returns:
anychart.scales.DateTime - Self instance for method chaining.Try it:
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.
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.DateTime - 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.getType
inverseTransform
Returns tick by its position ratio.
Note: returns correct values only after anychart.scales.Base#finishAutoCalc or chart.draw().
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 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.
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 |
---|---|---|---|
enabled | boolean | false | Inverted state to set. |
Returns:
anychart.scales.DateTime - Self instance for method chaining.Try it:
maxTicksCount
Getter for the maximum ticks count.
Returns:
number - Maximum ticks count. See listing
var maxTicksCount = scale.maxTicksCount();
Setter for the maximum ticks count.
Detailed description
Use this method only if you set the ticks with the anychart.scales.ScatterTicks#interval method.
It is ignored if the number of ticks is set manually via the method anychart.scales.ScatterTicks#count.
The method does not summarize both major and minor ticks, considering each separately, but the whole range from minimum to maximum.
If the number of ticks is greater than the passed value, the auto-calculation drops the interval from 4 to 6 ticks.
