minimum, maximum,
and interval values from the charting data
to fit all of the chart elements on the screen.
You can also explicitly set specific values for these properties.
A LogAxis object cannot correctly render negative values,
as Log10() of a negative number is undefined.

속성 세부 정보
interval | 속성 |
interval:Number| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Specifies the multiplier label values along the axis.
A value of 10 generates labels at 1, 10, 100, 1000, etc.,
while a value of 100 generates labels at 1, 100, 10000, etc.
Flex calculates the interval if this property
is set to NaN.
Intervals must be even powers of 10, and must be greater than or equal to 10.
The LogAxis rounds the interval down to an even power of 10, if necessary.
기본값: 10.

| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Specifies the maximum value for an axis label.
If NaN, Flex determines the maximum value
from the data in the chart.
The maximum value must be an even power of 10.
The LogAxis rounds an explicit maximum value
up to an even power of 10, if necessary.
기본값: NaN.

| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Specifies the maximum number of decimal places for representing fractional values on the labels generated by this axis. By default, the Axis autogenerates this value from the labels themselves. A value of 0 round to the nearest integer value, while a value of 2 rounds to the nearest 1/100th of a value.

Specifies the minimum value for an axis label.
If NaN, Flex determines the minimum value
from the data in the chart.
The minimum value must be an even power of 10.
The LogAxis will round an explicit minimum value
downward to an even power of 10 if necessary.
기본값: NaN.
