Class AAxisTransformation.YDataAccessor

Method Details

• scaleTrace

  protected void scaleTrace(ITrace2D trace, Range range)

  Description copied from class: AAxis.AChart2DDataAccessor

  Scales the given trace in the dimension represented by this axis.

  This method is not deadlock - safe and should be called by the Chart2D only!

  Overrides:

  scaleTrace in class AAxis<T extends AxisScalePolicyTransformation>.YDataAccessor

  Parameters:

  trace - the trace to scale.

  range - the range to use as scaler.

• translatePxToValue

  public double translatePxToValue(int pixel)

  Description copied from class: AAxis.AChart2DDataAccessor

  Transforms the given pixel value (which has to be a awt value like MouseEvent.getX() into the chart value.

  Internal use only, the interface does not guarantee that the pixel corresponds to any valid awt pixel value within the chart component.

  Warning: A value transformed to a pixel by AAxis.AChart2DDataAccessor.translateValueToPx(double) and then retransformed by AAxis.AChart2DDataAccessor.translatePxToValue(int) will most often have changed, as the transformation from value to px a) has to hit an exact int b) most often will map from a bigger domain (value range) to a smaller one (range of chart on the screen).

  Overrides:

  translatePxToValue in class AAxis<T extends AxisScalePolicyTransformation>.YDataAccessor

  Parameters:

  pixel - a pixel value of the chart component as used by awt.

  Returns:

  the awt pixel value transformed to the chart value.

  See Also:

  • AAxis.YDataAccessor.translatePxToValue(int)

• translateValueToPx

  public final int translateValueToPx(double value)

  Description copied from class: AAxis.AChart2DDataAccessor

  Transforms the given chart data value into the corresponding awt pixel value for the chart.

  The inverse transformation to AAxis.AChart2DDataAccessor.translatePxToValue(int).

  Overrides:

  translateValueToPx in class AAxis<T extends AxisScalePolicyTransformation>.YDataAccessor

  Parameters:

  value - a chart data value.

  Returns:

  the awt pixel value corresponding to the chart data value.
