hatch - Draw hatch.

hatch
    ( var ( min max | -min min | -max max ) | varmin varmax )

To show help, simply run "hatch".

var

Variable.

min, max

Value range to be drawn (default: [-1e+30:1e+30]).

varmin, varmax

Variable range (only for 1D chart).

angle

Anti-clockwise angle of the hatch (default: 45). hatch is parallel to +X axis when angle=0. You can specify two or more angles by comma-separated values, e.g., -angle 45,90.

density

Density (or accuracy) of the hatch (default: 0.01).

int

Hatch interval (default: 0.1).

color

Hatch color (default: 1).

type

Hatch line type (default: 1).

thickness

Hatch line thickness (default: 1).

(1) Draw hatch on lat-lon figure.

ga-> open u.ctl
ga-> set lev 500
ga-> set lat -90 90
ga-> set lon 0 360
ga-> d u
ga-> hatch u 20 100

(2) Draw vertical hatch on lat-time figure.

ga-> open t.ctl
ga-> set t 1 12
ga-> set lat 0 90
ga-> set lon 0
ga-> d t
ga-> hatch t 280 290 -angle 90

(3) Overlap hatch.

ga-> open t.ctl
ga-> d t
ga-> hatch t 200 270 -angle 45,135
ga-> hatch t 300 320 -angle 0,90

(4) Draw hatch on 1D figure.

ga-> open hgs.ctl
ga-> set lat 30
ga-> d hgs
ga-> hatch hgs 1000 6000 -color 2

(5) Draw hatch on 1D figure like linefill.

ga-> open t.ctl
ga-> set lat 40
ga-> d t
ga-> hatch t-5 t+5
