Y must have 130 the same dimensions as X. The vector at point [i,j] has a 131 magnitude of: 132 133 (U[i,j]^2 + V[i,j]^2)^0.5 134 135 and a direction of: 136 137 ATAN2(V[i,j],U[i,j]). 138 139 OPTIONAL INPUT PARAMETERS: 140 X: Optional abcissae values. X must be a vector with a length 141 equal to the first dimension of U and V. 142 143 Y: Optional ordinate values. Y must be a vector with a length 144 equal to the first dimension of U and V. 145 146 KEYWORD INPUT PARAMETERS: 147 COLOR: The color index used for the plot. 148 149 DOTS: Set this keyword to 1 to place a dot at each missing point. 150 Set this keyword to 0 or omit it to draw nothing for missing 151 points. Has effect only if MISSING is specified. 152 153 LENGTH: Length factor. The default of 1.0 makes the longest (U,V) 154 vector the length of a cell. 155 156 MISSING: Missing data value. Vectors with a LENGTH greater 157 than MISSING are ignored. 158 159 OVERPLOT: Set this keyword to make VELOVECT "overplot". That is, the 160 current graphics screen is not erased, no axes are drawn, and 161 the previously established scaling remains in effect. 162 163 164 Note: All other keywords are passed directly to the PLOT procedure 165 and may be used to set option such as TITLE, POSITION, 166 NOERASE, etc. 167 OUTPUTS: 168 None. 169 170 COMMON BLOCKS: 171 None. 172 173 SIDE EFFECTS: 174 Plotting on the selected device is performed. System 175 variables concerning plotting are changed. 176 177 RESTRICTIONS: 178 None. 179 180 PROCEDURE: 181 Straightforward. Unrecognized keywords are passed to the PLOT 182 procedure. 183 184 MODIFICATION HISTORY: 185 DMS, RSI, Oct., 1983. 186 For Sun, DMS, RSI, April, 1989. 187 Added TITLE, Oct, 1990. 188 Added POSITION, NOERASE, COLOR, Feb 91, RES. 189 August, 1993. Vince Patrick, Adv. Visualization Lab, U. of Maryland, 190 fixed errors in math. 191 August, 1993. DMS, Added _EXTRA keyword inheritance. 192 January, 1994, KDB. Fixed integer math which produced 0 and caused 193 divide by zero errors. 194 December, 1994, MWR. Added _EXTRA inheritance for PLOTS and OPLOT. 195 June, 1995, MWR. Removed _EXTRA inheritance for PLOTS and changed 196 OPLOT to PLOTS. 197 September, 1996, GGS. Changed denominator of x_step and y_step vars. 198 February, 1998, DLD. Add support for CLIP and NO_CLIP keywords. 199 June, 1998, DLD. Add support for OVERPLOT keyword.</div> 110 200 111 201 -

02 14:44:47Z pinsard Copyright c 1990 2000 Research Systems Inc All rights reserved Unauthorized reproduction prohibited PURPOSE: Create a bar graph or overplot on an existing one CATEGORY: Graphics CALLING SEQUENCE: BAR_PLOT Values INPUTS: Values: A vector containing the values to be represented by the bars Each element in VALUES corresponds to a single bar in the output KEYWORD PARAMETERS: BASELINES: A vector the same size as VALUES that contains the base value associated with each bar If not specified a base value of zero is used for all bars COLORS: A vector the same size as VALUES containing the color index to be used for each bar If not specified the colors are selected based on spacing the color indices as widely as possible within the available colors specified by D N_COLORS BARNAMES: A string array containing one string label per bar If the bars are vertical the labels are placed beneath them If horizontal rotated bars are specified the labels are placed to the left of the bars TITLE: A string containing the main title to for the bar plot XTITLE: A string containing the title for the X axis YTITLE: A string containing the title for the Y axis BASERANGE: A floating point scalar in the range 0 0 to 1 0 that determines the fraction of the total available plotting area in the direction perpendicular to the bars to be used If not specified the full available area is used BARWIDTH: A floating point value that specifies the width of the bars in units of nominal bar width The nominal bar width is computed so that all the bars and the space between them set by default to 20 of the width of the bars will fill the available space optionally controlled with the BASERANGE keyword BARSPACE: A scalar that specifies in units of nominal bar width the spacing between bars For example if BARSPACE is 1 0 then all bars will have one bar width of space between them If not specified the bars are spaced apart by 20 of the bar width BAROFFSET: A scalar that specifies the offset to be applied to the first bar in units of nominal bar width This keyword allows for example different groups of bars to be overplotted on the same graph If not specified the default offset is equal to BARSPACE OUTLINE: If set this keyword specifies that an outline should be drawn around each bar OVERPLOT: If set this keyword specifies that the bar plot should be overplotted on an existing graph BACKGROUND: A scalar that specifies the color index to be used for the background color By default the normal IDL background color is used ROTATE: If set this keyword indicates that horizontal rather than vertical bars should be drawn The bases of horizontal bars are on the left Y axis and the bars extend to the right OUTPUTS: A bar plot is created or an existing one is overplotted EXAMPLE: By using the overplotting capability it is relatively easy to create stacked bar charts or different groups of bars on the same graph For example if ARRAY is a two dimensional array of 5 columns and 8 rows it is natural to make a plot with 5 bars each of which is a stacked composite of 8 sections First create a 2D COLORS array equal in size to ARRAY that has identical color index values across each row to ensure that the same item is represented by the same color in all bars With ARRAYS and COLORS defined the following code fragment illustrates the creation of stacked bars note that the number of rows and columns is arbitrary : Y RANGE 0 ymax Scale range to accommodate the total bar lengths BASE INTARR NROWS FOR I 0 NROWS 1 DO BEGIN BAR_PLOT

All rights reserved Unauthorized reproduction prohibited PURPOSE: Create a bar graph or overplot on an existing one CATEGORY: Graphics CALLING SEQUENCE: BAR_PLOT Values INPUTS: Values: A vector containing the values to be represented by the bars Each element in VALUES corresponds to a single bar in the output KEYWORD PARAMETERS: BASELINES: A vector the same size as VALUES that contains the base value associated with each bar If not specified a base value of zero is used for all bars COLORS: A vector the same size as VALUES containing the color index to be used for each bar If not specified the colors are selected based on spacing the color indices as widely as possible within the available colors specified by D N_COLORS BARNAMES: A string array containing one string label per bar If the bars are vertical the labels are placed beneath them If horizontal rotated bars are specified the labels are placed to the left of the bars TITLE: A string containing the main title to for the bar plot XTITLE: A string containing the title for the X axis YTITLE: A string containing the title for the Y axis BASERANGE: A floating point scalar in the range 0 0 to 1 0 that determines the fraction of the total available plotting area in the direction perpendicular to the bars to be used If not specified the full available area is used BARWIDTH: A floating point value that specifies the width of the bars in units of nominal bar width The nominal bar width is computed so that all the bars and the space between them set by default to 20 of the width of the bars will fill the available space optionally controlled with the BASERANGE keyword BARSPACE: A scalar that specifies in units of nominal bar width the spacing between bars For example if BARSPACE is 1 0 then all bars will have one bar width of space between them If not specified the bars are spaced apart by 20 of the bar width BAROFFSET: A scalar that specifies the offset to be applied to the first bar in units of nominal bar width This keyword allows for example different groups of bars to be overplotted on the same graph If not specified the default offset is equal to BARSPACE OUTLINE: If set this keyword specifies that an outline should be drawn around each bar OVERPLOT: If set this keyword specifies that the bar plot should be overplotted on an existing graph BACKGROUND: A scalar that specifies the color index to be used for the background color By default the normal IDL background color is used ROTATE: If set this keyword indicates that horizontal rather than vertical bars should be drawn The bases of horizontal bars are on the left Y axis and the bars extend to the right OUTPUTS: A bar plot is created or an existing one is overplotted EXAMPLE: By using the overplotting capability it is relatively easy to create stacked bar charts or different groups of bars on the same graph For example if ARRAY is a two dimensional array of 5 columns and 8 rows it is natural to make a plot with 5 bars each of which is a stacked composite of 8 sections First create a 2D COLORS array equal in size to ARRAY that has identical color index values across each row to ensure that the same item is represented by the same color in all bars With ARRAYS and COLORS defined the following code fragment illustrates the creation of stacked bars note that the number of rows and columns is arbitrary : Y RANGE 0 ymax

theorie: sur la sphere un vecteur en un point donne a pour direction la tangente au cercle qui passe par le centre de la terre et par le vecteur Donc trouver la direction une fois la projection faite ds le plan 2d c est trouver la tangente a la courbe representant la projection du cercle sur le plan 2d au point representant la projection du point de depart de la shere sur le plan 2d En pratique on ne connait pas la definition de la courbe que donne la projection d un cercle alors trouver sa tangente en un point Ce que l on fait: Ds un repere cartesien 3d a on trouve les coordonnees du point T debut de la fleche situe sur la shere b pour chaque point T on determine les directions locales definies par la grille en ce point et auxquelles se rapportent les coordonnes u v du vecteur Ces directions locales sont definies par les gradiants des glam et gphi Une fois ces directions obtenues on les considere comme orthogonales et en les normant on construit un repere orthonormal nu nv auquel se rapporte les coordonnes u v du vecteur Ds le repere cartesien 3d de depart le vecteur est definit par: V u nu v nv ou V nu et nv sont des vecteurs 3d et u et v des scalaires c pour approximer la tangente au cercle par la corde definie par le debut et la fin de la fleche on va normaliser V puis le diviser par 100 d ceci nous permet de determiner les coordonnees ds le repere
