getTraces

java.util.Set<ITrace2D> getTraces()

Returns a Set<ITrace2D> with all traces covered by this axis.

Caution!
The original internal modifiable set is returned for performance reasons and by contract (to allow removing traces) so do not mess with it to avoid ugly unpredictable side effects!

Returns:

a Set<ITrace2D> with all traces covered by this axis.

getWidth

int getWidth(java.awt.Graphics g2d)

Returns the width in pixel this axis needs to paint itself.

This includes the axis line, it's ticks and labels and it's title.

g2d - needed for font metric information.

Returns:

the width in pixel this axis needs to paint itself.

hasTrace

boolean hasTrace(ITrace2D trace)

Parameters:

trace - the trace to check for containment.

Returns:

true if this axis is responsible for rendering the scale of the given trace (addTrace(ITrace2D) was called on this instance with the given trace).

initPaintIteration

void initPaintIteration()

Allows to perform expensive calculations for various values that are used by many calls throughout a paint iterations.

These values are constant throughout a paint iteration by the contract that no point is added removed or changed in this period. Because these values are used from many methods it is impossible to calculate them at a "transparent" method that may perform this caching over a paint period without knowledge from outside. The first method called in a paint iteration is called several further times in the iteration. So this is the common hook to invoke before painting a chart.

isDirtyScaling

boolean isDirtyScaling()

Returns true if the bounds in the given dimension of all TracePoint2D instances of all internal ITrace2D instances have changed since all points have been normalized to a value between 0 and 1 or true if this axis has different range since the last call to scale().

Returns:

true if the bounds in the given dimension of all TracePoint2D instances of all internal ITrace2D instances have changed since all points have been normalized to a value between 0 and 1 or true if this axis has different range since the last call to scale().

Returns:

wether the x grid is painted or not.

isPaintScale

Returns:

true if scale values start from major ticks.

See Also:

AAxis.setMajorTickSpacing(double)

isVisible

boolean isVisible()

Returns:

the visibility state of this axis

paint

void paint(java.awt.Graphics g2d)

Renders the axis line along with title, scale, scale labels and unit label.

This should only be called from Chart2D, all other uses may cause damaged UI or deadlocks.

Returns:

the width consumed in pixel for y axis, the height consumed in pixel for x axis.

removeAllTraces

java.util.Set<ITrace2D> removeAllTraces()

Convenience method for removing all contained ITrace2D instances of this axis.

Implementations should fire a PropertyChangeEvent for the PropertyChangeEvent.getPropertyName() PROPERTY_ADD_REMOVE_TRACE for every single trace removed. This is done best by delegating this call to several calls to removeTrace(ITrace2D).

Returns:

a shallow copy of the set of traces that were contained before.

removePropertyChangeListener

void removePropertyChangeListener(java.lang.String property,
                                  java.beans.PropertyChangeListener listener)

If listener was added more than once to the same event source for the specified property, it will be notified one less time after being removed. If propertyName is null, no exception is thrown and no action is taken. If listener is null, or was never added for the specified property, no exception is thrown and no action is taken.

Parameters:

property - The name of the property that was listened on.

listener - The PropertyChangeListener to be removed.

See Also:

PropertyChangeSupport.removePropertyChangeListener(java.lang.String, java.beans.PropertyChangeListener)

removeTrace

boolean removeTrace(ITrace2D trace)

Removes the given trace from this axis.

A PropertyChangeEvent for the PropertyChangeEvent.getPropertyName() PROPERTY_ADD_REMOVE_TRACE has to be fired on the registered PropertyChangeListener for the trace removed.

Parameters:

trace - the trace to remove from this axis.

Returns:

true if the given trace could be removed from this axis, false else.

scale

void scale()

Scales all ITrace2D instances in the dimension represented by this axis.

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

scaleTrace

void scaleTrace(ITrace2D trace)

Scales the given ITrace2D in the dimension represented by this axis.

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

Parameters:

trace - the trace to scale.

setAxisTitle

void setAxisTitle(IAxis.AxisTitle axisTitle)

Sets the title of this axis.

Parameters:

axisTitle - the axis title to use.

setFormatter

void setFormatter(IAxisLabelFormatter formatter)

Sets the formatter to use for labels.

Parameters:

formatter - The formatter to set.

setMajorTickSpacing

void setMajorTickSpacing(double majorTickSpacing)

This method sets the major tick spacing for label generation.

Only values between 0.0 and 100.0 are allowed.

The number that is passed in represents the distance, measured in values, between each major tick mark. If you have a trace with a range from 0 to 50 and the major tick spacing is set to 10, you will get major ticks next to the following values: 0, 10, 20, 30, 40, 50.

Note:
Ticks are free of any multiples of 1000. If the chart contains values between 0 an 1000 and configured a tick of 2 the values 0, 200, 400, 600, 800 and 1000 will highly probable to be displayed. This depends on the size (in pixels) of the Chart2D<. Of course there is a difference: ticks are used in divisions and multiplications: If the internal values are very low and the ticks are very high, huge rounding errors might occur (division by ticks results in very low values a double cannot hit exactly. So prefer setting ticks between 0 an 10 or - if you know your values are very small (e.g. in nano range [10 ^-9 ]) use a small value (e.g. 2*10 ^-9 ).

Parameters:

majorTickSpacing - the major tick spacing for label generation.

setMinorTickSpacing

void setMinorTickSpacing(double minorTickSpacing)

This method sets the minor tick spacing for label generation.

The number that is passed-in represents the distance, measured in values, between each minor tick mark. If you have a trace with a range from 0 to 10 and the minor tick spacing is set to 2, you will get major ticks next to the following values: 0, 2, 4, 6, 8, 10. If a major tick hits the same values the tick will be a major ticks. For this example: if a major tick spacing is set to 5 you will only get minor ticks for: 2, 4, 6, 8.

Note:
Ticks are free of any powers of 10. There is no difference between setting a tick to 2, 200 or 20000 because ticks cannot break the rule that every scale label has to be visible. If the chart contains values between 0 an 1000 and configured a tick of 2 the values 0, 200, 400, 600, 800 and 1000 will highly probable to be displayed. This depends on the size (in pixels) of the Chart2D<. Of course there is a difference: ticks are used in divisions and multiplications: If the internal values are very low and the ticks are very high, huge rounding errors might occur (division by ticks results in very low values a double cannot hit exactly. So prefer setting ticks between 0 an 10 or - if you know your values are very small (e.g. in nano range [10 ^-9 ]) use a small value (e.g. 2*10 ^-9 ).

Parameters:

minorTickSpacing - the minor tick spacing to set.
