|
Method Summary | |
---|---|
private void |
AssignContourValues()
interpolate between zMin and zMax , logarithmically or linearly, in order to assign contour
values to the array cv |
private double |
ClipX(double x)
|
private double |
ClipY(double y)
|
private void |
ContinueContour()
continues tracing a contour. |
private void |
ContourPlotKernel(Graphics g,
boolean[] workSpace)
corresponds to Synder's subroutine "GCONTR". |
private boolean |
CrossedByContour(boolean[] workSpace)
true iff the current segment in the grid is crossed by one of the contour values and has not already been processed for that value. |
private void |
DetectBoundary()
|
private void |
DrawKernel(Graphics g)
the guts of drawing and is called directly or indirectly by ContourPlotKernel(Graphics, boolean[]) in
order to draw a segment of a contour or to set the pen position "prevXY". |
private void |
DrawProfile(Graphics g,
ContourPlot.Profile profile)
|
private Color |
GetColour(int index)
|
private void |
GetExtremes()
scans the data in z in order to assign values to zMin and zMax |
private void |
InvalidData()
sets the first two components of the contour value array to equal values, thus preventing subsequent drawing of the contour plot. |
private void |
MakeMatrixRectangular()
appends zero(s) to the end of any row of "z" which is shorter than the longest row. |
void |
paint(Graphics g)
draws the contours provided that the first two contour values are not equal (which would indicate invalid data) |
private boolean |
Routine_label_020()
corresponds to a block of code starting at label 20 in Synder's subroutine "GCONTR". |
private boolean |
Routine_label_050()
corresponds to a block of code starting at label 50 in Synder's subroutine "GCONTR". |
private boolean |
Routine_label_150()
corresponds to a block of code starting at label 150 in Synder's subroutine "GCONTR". |
private short |
Routine_label_200(Graphics g,
boolean[] workSpace)
corresponds to a block of code starting at label 200 in Synder's subroutine "GCONTR". |
private void |
SetColour(Graphics g)
sets the colour of the graphics object, given the contour index, by interpolating linearly between Color.BLUE & Color.red |
void |
setFill(boolean fill)
|
void |
setLogInterpolation(boolean logInterpolation)
|
void |
setNumberOfContours(int numberOfContours)
|
void |
setPalette(Color[] palette)
|
void |
setZedMatrix(cern.colt.matrix.DoubleMatrix2D zed)
|
private int |
sign(int a,
int b)
