11 | ; 'plt', 'pltz' or 'pltt' |

12 | ; |
---|
13 | ; @param POSFENETRE {out}{type=vector} |
---|
14 | ; It is a vector composed by 4 elements containing the position of the frame |
---|
15 | ; containing captions and the graph in normalized coordinates. |
---|
16 | ; Comment: To position the drawing; we have to do !p.position=posfenetre |
---|
17 | ; after the call of the caliber |
---|
18 | ; |
---|
19 | ; @param POSBAR {out}{type=vector} |
---|
20 | ; Like POSFENETRE but for the color bar. |
---|
21 | ; Same comment to position the color bar, !p.position=posbar |
---|
22 | ; |
---|
23 | ; @param dtasize {in}{optional}{type=2 elements vector} |
---|
24 | ; used by pltv to specify the size of the array that wil be plotted |
---|
25 | ; and therefore the default yxaspect to be used. |
---|
26 | ; |
---|
27 | ; @keyword LANDSCAPE |
---|
28 | ; Force the page or the window on the screen to be in lengthened position. |
---|
29 | ; |
---|
30 | ; @keyword LCT {type=integer} |
---|
31 | ; It designate the number of the palette of color we want to use for the plot. |
---|
32 | ; |
---|
33 | ; @keyword MAP |
---|
34 | ; We use it when we want to do a projection. |
---|
35 | ; This keyword can be of two types: |
---|
36 | ; MAP=[P0lat,P0lon,Rot]. For the description of these 3 values (see the online help of MAP_SET). |
---|
37 | ; /MAP: In this case, map is automatically calculated have the value: |
---|
38 | ; map = [0, (lon1+lon2)/2., 0] |
---|
39 | ; Comment 1: A good way to choose the type of the projection we want to do is to have a look at IDL demo: |
---|
40 | ; IDL> demo |
---|
41 | ; Then choose earth sciences and mapping. |
---|
42 | ; Comment 2: By default it is a cylindrical projection which is effectuated (with or without the keyword map). |
---|
43 | ; If we want an other projection, MAP must be activated and we have to add the keyword: /nom_projection. |
---|
44 | ; For example, for a polar projection centered on the south pole: |
---|
45 | ; IDL> domdef,-180,180,-90,-45 |
---|
46 | ; IDL> plt, tab, /stereo,map=[-90,0,0] |

57 | ; @keyword SMALL |
---|
58 | ; Vector composed of 3 or 4 elements, applied to make a drawing on a |
---|
59 | ; small portion of a page or screen. It delimit the zone where the drawing will be done. |
---|
60 | ; If there is 4 elements: |
---|
61 | ; then is constituted of coordinates (expressed in cm located from the up and |
---|
62 | ; left corner of the page or the window (in portrait like in landscape) of the bottom |
---|
63 | ; and left corner and of the up and right corner of the drawing zone. |
---|
64 | ; If there is 3 elements: |
---|
65 | ; in this case, we divide the page or the screen in small[0] columns and in small[1] lines |
---|
66 | ; the drawing made in the box numbered small[2]. The numerotation starting up and left by |
---|
67 | ; the number 1 and then, following the writing direction. |
---|
68 | ; By default, we make the largest drawing we can do, conserving the aspect rapport |
---|
69 | ; (except when REMPLI is activated). |
---|
70 | ; |

71 | ; @keyword PORTRAIT |
---|
72 | ; Force the page or the window to be in standing position. |

86 | ; The colorbar's title |
---|
87 | ; |

88 | ; @keyword CONTOUR |
---|
89 | ; If we want to trace contours of a different field than the one |
---|
90 | ; whose we have the colored drawing (by example E-P in color and QSR in contours). |

93 | ; |
---|
94 | ; @keyword ENDPOINTS |
---|
95 | ; keyword specifying that we want to make a vertical cut in diagonal. Then coordinated of extremities |

97 | ; coordinates. |

---|
102 | ; to draw. These fields can be an array or a structure. |
---|
103 | ; For example: vecteur={matriceu:lec('unsurface'),matricev:lec('vnsurface')} |
