StackGanger
protected StackGanger(boolean isUp, Padding padding)
Constructor. The supplied padding is currently applied outside each plot zone. That's not the only way to do it; you could imagine wanting to apply this padding outside the union of plot zones, or to be able to supply different paddings for each zone.- Parameters:
isUp
- true if zones are ordered upwards on the graphics plane, false if they go downpadding
- defines user preferences, if any, for space reserved outside each plot zone

Method Detail

getXLimits
public abstract double[] getXLimits(A aspect)
Returns the data limits of the horizontal axis defined by a given aspect.- Parameters:
aspect
- surface aspect- Returns:
- 2-element array giving (min,max) values of data coordinates on the horizontal axis
-
fixXLimits
public abstract A fixXLimits(A aspect, double xmin, double xmax)
Modifies an aspect object to give it fixed data limits on the horizontal axis.- Parameters:
aspect
- input surface aspectxmin
- required lower limit on horizontal axisxmax
- required upper limit on horizontal axis- Returns:
- new aspect resembling input aspect but with supplied horizontal axis limits
-
createGang
public Gang createGang(java.awt.Rectangle[] zonePlotBounds)
Description copied from interface:Ganger
Creates a gang given the graphics coordinates of the individual zones. This can be used if the layout of the zones is already known.The supplied rectangle arguments give the bounds of the data area for each zone. This does not include any space for axis labels and other annotations, which are assumed to be available as required.
- Specified by:
createGang
in interfaceGanger<P,A>
- Parameters:
zonePlotBounds
- array of data bounds, one for each zone- Returns:
- new gang
-
createGang
public Gang createGang(java.awt.Rectangle gangExtBox, SurfaceFactory<P,A> surfFact, int nz, ZoneContent[] contents, P[] profiles, A[] aspects, ShadeAxis[] shadeAxes, boolean withScroll)
Description copied from interface:Ganger
Creates a gang given the external bounds for the whole plotting area and other required information that characterises each zone. The supplied aspects are not modified by this method; any required aspect resolution should be performed before calling it.- Specified by:
createGang
in interfaceGanger<P,A>
- Parameters:
gangExtBox
- total area enclosing all zones and associated axis labels, annotations etcsurfFact
- surface factorynz
- number of zonescontents
- plot content for each zone (nz-element array)profiles
- profile for each zone (nz-element array)aspects
- aspect for each zone (nz-element array)shadeAxes
- shading axis for each zone (nz-element array, elements may be empty)withScroll
- true if the positioning should work well even after some user scrolling- Returns:
- new gang
-
createApproxGang
public Gang createApproxGang(java.awt.Rectangle extBounds, int nz)
Description copied from interface:Ganger
Constructs an approximate gang instance given only minimal information. This may be sufficient for passing the user a visual indication of roughly how zones are arranged, or making initial guesses at zone dimensions.- Specified by:
createApproxGang
in interfaceGanger<P,A>
- Parameters:
extBounds
- total area enclosing all zones and associated axis labels, annotations etcnz
- number of zones- Returns:
- new approximate gang
-
adjustAspects
public A[] adjustAspects(A[] aspects, int index)
Description copied from interface:Ganger
Adjusts plot surface aspects as required to ensure that plot data regions in a ganged set of zones are consistent.If a zero reference index greater than zero is supplied, this denotes the "master" zone, to which the other aspects should be adjusted. Otherwise, the aspects should be adjusted more democratically, treating all their requirements equally. With a reference index the other aspects might be adjusted to equal the master one, and without they might all be adjusted to cover the union of the ranges defined. If the reference index is >= the number of zones, behaviour is undefined.
- Specified by:
adjustAspects
in interfaceGanger<P,A>
- Parameters:
aspects
- unadjusted aspectsindex
- index of reference aspect in array, or -1 for no reference- Returns:
- array of consistent aspects based on input array, same size as input
-
adjustProfiles
public P[] adjustProfiles(P[] profiles)
Description copied from interface:Ganger
Adjusts plot surface profiles as required for plots appearing in multiple plots within a gang.- Specified by:
adjustProfiles
in interfaceGanger<P,A>
- Parameters:
profiles
- unadjusted profiles- Returns:
- array of consistent profiles based on input array, same size as input
