- Compute contour lines for a 2-D array. If the interval is negative,
then contour lines less than base will be drawn as dashed lines.
The contour lines will be computed for all V such that:
lowlimit <= V <= highlimit
and V = base + n*interval for some integer n
Note that the input array, g, should be in column-major (FORTRAN) order.
- Parameters:
g
- the 2-D array to contour.nr
- size of 2-D array in rowsnc
- size of 2-D array in columns.interval
- contour intervallowlimit
- the lower limit on values to contour.highlimit
- the upper limit on values to contour.base
- base value to start contouring at.vx1

intervalToLevels
public static float[] intervalToLevels(float interval,
float low,
float high,
float ba,
boolean[] dash)
throws VisADException
- Returns an array of contour values and an indication on whether to use
dashed lines below the base value.
- Parameters:
interval
- The contouring interval. Must be non-zero.
If the interval is negative, then contour lines
less than the base will be drawn as dashed
lines. Must not be NaN.low
- The minimum contour value. The returned array
will not contain a value below this. Must not
be NaN.high
- The maximum contour value. The returned array
will not contain a value above this. Must not
be NaN.ba
- The base contour value. The returned values
will be integer multiples of the interval
away from this this value. Must not be NaN.
dash Whether or not contour lines less than the base
should be drawn as dashed lines. This is a
computed and returned value.
- Throws:
VisADException
- The contour interval is zero or too small.
