Internal Plotting Parameters

Internal Plotting Parameters (default.cnt)

The internal plotting parameters of the ROMS plotting package are controlled buy the default.cnt file. This configuration file allows you to adjust things like font size and line thickness. This page is intended as a reference for the options contained in this file. A sample default.cnt can be found in the Data directory of the source code.

---

LVPINFO

Switch to print out viewport information (T/F). If you set this to T the output to the terminal from the ccnt or csec command will include additional information about the dimensions of the resulting plots.

Default Value: F

Sample output from csec

SEC_FRAME - plots/page = 1
SEC_FRAME - current plot = 1
SEC_FRAME - frame left = 0.0909
SEC_FRAME - frame right = 0.8182
SEC_FRAME - frame bottom = 0.1818
SEC_FRAME - frame top = 0.7955
SEC_FRAME - box Xmin = 0.0000
SEC_FRAME - box Xmax = 81.0000
SEC_FRAME - box Zmin = -150.0000
SEC_FRAME - box Zmax = 0.0000

Default Value: F

LNOZERO

Switch to omit drawing of zero-contour line (T/F) for overlays.

Default Value: T

LCNTLAB

Switch to label contour lines (T/F) for overlays.

Default Value: T

CNT_CLL

Width of labeled contour lines: [0] default, [2] double for overlays.

Default Value: 0

LDRWUSR

Switch to draw user lines (T/F).

Default Value: T

LHIGLOW

Switch to label High/Low contour labels (T/F).

Default Value: F

LMODDAY

Default Value: T

LDOMAIN

Switch to draw domain box (T/F).

Default Value: T

LFRAME

Switch to draw NCAR frame box (T/F).

Default Value: T

LTMARKS

Switch to draw box tick marks and labels (T/F).

Default Value: T

LCLRBAR

Switch to draw color bar (T/F).

Default Value: T

LVECRHO

Switch to draw vectors at RHO-points (F: at PSI-points).

Default Value: T

LVCOLOR

Switch to paint vectors by their magnitude (T/F).

Default Value: T

LROTVEC

Switch to rotate vector component normal to cross-section.

Default Value: F

LZEROZN

Switch to set surface depth to zero in cross-sections.

Default Value: T

THCKUSR

User polylines thickness.

Default Value: 2.0

VEC_VPO

Vector positioning mode: [<0] head, [0] middle, [>0] tail. This sets what part of the vector is located at the RHO-points (or PSI-points if LVECRHO is F).

Default Value: 1 (tail)

VEC_AMN

Vector arrow minimum size (fraction of viewport width).

Default Value: 0.0007

VEC_AMX

Vector arrow maximum size (fraction of viewport width).

Default Value: 0.05

VEC_VLC

Vector low cutoff percentage.

Default Value: 0.05

VEC_VFR

Vector fractional minimum.

Default Value: 0.07

VEC_VRM

Vector reference magnitude (if zero, use maximum cutoff).

Default Value: 0.0

VEC_MXX

Maximum vector text block X-coordinate.

Default Value: 0.85

VEC_MXY

Maximum vector text block Y-coordinate.

Default Value: -0.07

SECAXIS

Section axis coordinate labels: [0] metric, [1] spherical.

Default Value: 0

COORSCL

Cartesian coordinate units: [0] km, [1] m, [2] cm, [3] mm

Default Value: 0

HVELSCL

H velocity: [0] m/s [1] cm/s [2] mm/s [3] -knots [4] -knots/2

Default Value: 1

WVELSCL

V velocity: [0] m/s [1] m/day [2] cm/day

Default Value: 2

ZREF

Reference depth (m) used to compute several quantities.

Default Value: 0.0

SMTHOUT

Smooth output: [0] no, [1] Bleck's filter, [2] Shapiro filter

Default Value: 0

NSAPPL

Number of applications of smoothing filter. This only has an effect if SMTHOUT is not 0.

Default Value: 1

NORD

Order of Shapiro filter. This only has an effect if SMTHOUT is set to 2.

Default Value: 4

FontSz1

Default Value: 20.0 plotter units

FontSz2

Font size for secondary top/bottom titles.

Default Value: 10.0 plotter units

FontSz3
