CALLING SEQUENCE: COLORBAR, Zrange [,Width] [,Height] [,X=x] [,Y=y] [,Wid=wid] INPUTS: Zrange: [Zmin,Zmax] specifies the minimum and maximum value of data corresponding to the first and last entry of color table. OPTIONAL INPUTS: Width: specify the width of the color bar, default to 20 pixels Height: specify the height of the color bar, default to 320 pixels KEYWORD PARAMETERS: X: specify X location of the lower left corner of the color bar, default to 70 pixels from right boundary for X device Y: specify Y location of the lower left corner of the color bar, default to 100 pixels from bottom boundary for X device Wid: specify the destination window the color bar to be drawn, default to current plot device Ncap: specify the number of value labels Format: specify the color bar label format PSfact: specify the PS color bar scaling factor, default is 30 Reverse: use black color for color bar text color Ncolors: specify the number of colors used from the table OFF: specify offset value for colorbar LOG: specify linear or log scale used OUTPUTS: None. RESTRICTION: The Width, Height are absolute pixel numbers respect to the actual plot device. The location X, and Y pixels respect to the plot device origin. EXAMPLE: Example 1 - Place a colorbar at the default location 70,100 pixels from the lower right corner of the plot area colorbar,[min(z),max(z)] Example 2 - Place a colorbar at the location 10,100 pixels from the lower left corner of the plot area colorbar,[min(z),max(z)],X=10,Y=100 MODIFICATION HISTORY: Written by: Ben-chin Cha, April 9, 1999 xx-xx-xxxx xxx Comment
