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.
The auto-determination of range values works as follows:
- Flex determines a minimum and maximum value that accomodates all the data being displayed in the chart.
- If the
autoAdjustandbaseAtZeroproperties are set totrue, Flex makes the following adjustments:- If all values are positive,
Flex sets the
minimumproperty to zero. - If all values are negative,
Flex sets the
maximumproperty to zero.
- If all values are positive,
Flex sets the
- If the
autoAdjustproperty is set totrue, Flex adjusts values of theminimumandmaximumproperties by rounding them up or down. - Flex checks if any of the elements displayed in the chart
require extra padding to display properly (for example, for labels).
It adjusts the values of the
minimumandmaximumproperties accordingly. - Flex determines if you have explicitly specified any padding
around the
minimumandmaximumvalues, and adjusts their values accordingly.

Specifies the maximum value for an axis label.
If you set the autoAdjust property to true,
Flex calculates this value.
If NaN, Flex determines the maximum value
from the data in the chart.
