XDataAccessor(Chart2D chart) Creates an instance that accesses the given chart's x axis.

Method Summary

Modifier and Type	Method and Description
protected void	scaleTrace(ITrace2D trace, Range range) Scales the given trace in the dimension represented by this axis.
double	translatePxToValue(int pixel) Transforms the given pixel value (which has to be a awt value like MouseEvent.getX() into the chart value.

Constructor Detail

XDataAccessor

public XDataAccessor(Chart2D chart)

Creates an instance that accesses the given chart's x axis.

Parameters:

chart - the chart to access.

Method Detail

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.XDataAccessor

Parameters:

trace - the trace to scale.

range - the range to use as scaler.

AAxis.XDataAccessor.scaleTrace(info.monitorenter.gui.chart.ITrace2D, info.monitorenter.util.Range)

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.XDataAccessor

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.XDataAccessor.translatePxToValue(int)

translateValueToPx

public final int translateValueToPx(double value)

Description copied from class: AAxis.AChart2DDataAccessor

Transforms the given relative value into the relative chart pixel value regarding the point's position.

This must only be used when the chart dimensions ( Chart2D.getXChartEnd(), Chart2D.getXChartStart(), ...) are already computed and valid.

Overrides:

translateValueToPx in class AAxis.XDataAccessor

Parameters:

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

Returns:

the relative awt pixel value transformed to the chart value.
