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 Selector also supports the Custom Label formats using the placeholders such as {value}$, in which the value represents the axis label, e.g. 20$.

Logarithmic Axis

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

Note: To use date-time scale, inject the DateTimeService into the @NgModule.providers.

Interval Customization

The DateTime intervals can be customized using the interval and the intervalType properties of the Range Selector. For example, if the interval is set to 2 and the intervalType is set to years, the interval will be considered to be 2 years.

DateTime supports the following interval types:

Auto
Years
Quarter
Months
Weeks
Days
Hours
Minutes
