getLabelEstimate | () | método |
public function getLabelEstimate():AxisLabelSet
Versión del lenguaje: | ActionScript 3.0 |
Versión de producto: | Flex 3 |
Versiones de motor de ejecución: | Flash Player 9, AIR 1.1 |
Determines the range to estimate what the axis labels should be.
The axis almost immediately calls the getLabels()
method
to get the real values.
The axis uses the estimated values to adjust chart margins,
so any difference between the estimated labels and actual labels
(returned from the getLabels()
method) results in scaling
the labels to fit.
An axis need only return the minimum and maximum labels when returning an estimate. If the label set is fairly static, without depending on the size of the axis being rendered on screen, an axis can return the entire label set from this function, and mark the estimate as accurate.
Valor devueltoAxisLabelSet — An Array of AxisLabel objects.

getLabels | () | método |
public function getLabels(minimumAxisLength:Number):AxisLabelSet
Versión del lenguaje: | ActionScript 3.0 |
Versión de producto: | Flex 3 |

Gets the labels text that is rendered. When Flex calls this method, the axis has already determined the minimum length of the label.
Parámetros
minimumAxisLength:Number — The minimum length of the axis, in pixels.
The axis can be longer than this value, but not shorter.
|
AxisLabelSet — An array of AxisLabel objects.
|

Versión del lenguaje: | ActionScript 3.0 |
Versión de producto: | Flex 3 |
Versiones de motor de ejecución: | Flash Player 9, AIR 1.1 |

| |
max:Number — The computed maximum value.
|
Array — null if no adjustment is necessary, or an Array containing the adjusted
values of the form [min,max] .
