      </RangenavigatorSeriesCollectionDirective>
    </RangeNavigatorComponent>
  }

};
ReactDOM.render(<App />, document.getElementById("charts"));

Range

Minimum and maximum of the Range navigator will be calculated automatically based on the provided data. You can also customize the range using the minimum, maximum, and interval properties.

Label Format

Numeric labels can be formatted using the labelFormat property.

Numeric labels support all globalized formats.

The following table describes the result of applying some commonly used label formats on numeric values.

Label Value	Label Format property value	Result	Description
1000	n1	1000.0	The Number is rounded to 1 decimal place
1000	n2	1000.00	The Number is rounded to 2 decimal place
1000	n3	1000.000	The Number is rounded to 3 decimal place
0.01	p1	1.0%	The Number is converted to percentage with 1 decimal place
0.01	p2	1.00%	The Number is converted to percentage with 2 decimal place
0.01	p3	1.000%	The Number is converted to percentage with 3 decimal place
1000	c1	$1,000.0	The Currency symbol is appended to number and number is rounded to 1 decimal place
1000	c2	$1,000.00	The Currency symbol is appended to number and number is rounded to 2 decimal place

Custom Label Format

The range navigator also supports custom label formats using placeholders such as {value}$, in which, the value represent the axis label, e.g. 20$.

Logarithmic Axis

Logarithmic supports logarithmic scale, and it is used to visualize data when the Range navigator has numerical values in both lower (e.g.: 10-6) and higher (e.g.: 106) orders of magnitude.

};
ReactDOM.render(<App />, document.getElementById("charts"));

Note: To use logarithmic scale, inject the Logarithmic module using the RangeNavigator.Inject(Logarithmic) method, and then set the valueType to Logarithmic.

Range

Minimum and maximum of the Range navigator will be calculated automatically based on the provided data. You can also customize the range using the minimum, maximum, and interval properties.

Note: Date-time Range navigator supports date-time scale and displays date-time values as a labels in the specified format.

Interval Customization

Date-time intervals can be customized using the interval and intervalType properties of the range navigator. For example, when you set interval as 2 and intervalType as years, the interval is considered as 2 years. Date-time supports the following interval types:

Auto
Years
Quarter
Months
Weeks
Days
Hours
Minutes
