Creates an instance that accesses the y axis of the given chart.- Parameters:
chart
- the chart to access.

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
only!Chart2D
- Overrides:
scaleTrace
in classAAxis.YDataAccessor
- Parameters:
trace
- the trace to scale.range
- the range to use as scaler.- See Also:
AAxis.YDataAccessor.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 likeMouseEvent.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 byAAxis.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 classAAxis.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 classAAxis.YDataAccessor
- Parameters:
value
- a chart data value.- Returns:
- the awt pixel value corresponding to the chart data value.
