pltbase.pro

Overlayer contour to trace a field which can be mask. Elementary brick of plt, pltz and pltt.

Parameters

z2d        in required

The table to trace

x        in required

Axis. Vector or array of the same size that z2d. This is the coordinate of z2d on x.

y        in required

Axis. Vector or array of the same size that z2d. This is the coordinate of z2d on y.

mask        in required type: array

It is the array who mask z2d (with 0s on points we want to mask and 1s on others). If z2d is not masked, put this argument equal to 1.

xm        in required

Axis of the mask. Vector or array of the same size that mask. This is the coordinate of mask on x.

ym        in required

Axis of the mask. Vector or array of the same size that mask. This is the coordinate of mask on y.

levels        in optional type: vector

Vectors which contain levels needed at the contour. If it is not given, we take 20 levels between the min and the max.

colors        in optional type: vector

Vectors which contain colors needed at the contour. If it is not given, we take 20 levels between the min and the max.

Keywords

UNSUR2       

To trace one isoline on two.

CONTOUR       

To be used since plt, pltz or pltt. (Have a look on these routines).

NOCONTOUR       

To make just colors.

NOFILL       

To make just isolines with no filling

TRICHAMP       

TRIMSK       

REALCONT       

NAN       

USETRI       

COLORTRICHAMP       

The color we want to use to draw the triangulation which is used to make contours of the field.

COLORTRIMASK       

The color we want to use to draw the triangulation which is used to make contours of the mask.

COLORTRINAN       

COLORPOINTS       

DRAWPOINTS       

TH_TRICHAMP       

TH_TRIMASK       

DESSTRICHAMP       

To draw the triangulation which is used to make field's contours.

DESSTRIMASK       

To draw the triangulation which is used to make mask's contours.

DESSTRINAN       

COLOR_C       

To draw the contour in color instead of in black with filling in color

I_COLORS        type: vector

It is a vector specifying the colors to use to trace contours. It is the same thing that c_colors which act on contours.

CONT_COLOR        default: (!d.n_colors - 1) < 255

The color of the continent.

CONT_NOFILL       

Activate it not to fill the point mask to let them transparent! Comment: Nevertheless, we trace mask's contour.

UNLABSUR        type: integer

I specify we only label one contour on two.

COINMONTEMASK       

COINDESCENDMASK       

COINMONTENAN       

COINDESCENDNAN       

INDICEZOOMMASK       

INDICEZOOMNAN       

MASKORG       

MASKNAN       

TRINAN       

FORPLT       

To activate if we want that the drawing of coast be realized by tracecote rather than tracemask.

REALSECTION       

MORE        default: 10

Number to give to avoid style's bugs: % Out of range subscript encountered: . % Execution halted at: PLTBASE 151 If the bug still exist, increase the value of more! (The explanation and the justification of this method do not have scientific bases yet...).

EXCHANGE_XY       

_EXTRA

History

Sebastien Masson (smasson@lodyc.jussieu.fr) ???? 8/2/2000 check if the tri array is not equal to -1. allow contour without using a triangulation.

Restrictions

In the case of z2d, x and y are arrays of same size, we have to put them as vectors: z2d[*], x[*], y[*].
