Range
Range for an axis, will be calculated automatically based on the provided data, you can also customize the range of the axis using minimum
, maximum
and interval
property of the axis.

Range Padding
Padding can be applied to the minimum and maximum extremes of the axis range by using the rangePadding
property. Numeric axis supports following types of padding.
- Round
- Normal
- Auto
Numeric - None
When the rangePadding
is set to None
, minimum and maximum of an axis is based on the data.

};
},
provide: {

Numeric - Round
When the rangePadding
is set to Round
, minimum and maximum will be
rounded to the nearest possible value divisible by interval. For example, when the minimum is 3.5 and the interval is 1, then the minimum will be rounded to 3.

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 | $1000.0 | The Currency symbol is appended to number and number is rounded to 1 decimal place |
1000 | c2 | $1000.00 | The Currency symbol is appended to number and number is rounded to 2 decimal place |
GroupingSeperator
To separate groups of thousands, use useGroupingSeparator
property in chart.
