 CATEGORY:

       color plotting

 CALLING SEQUENCE:

       hydra_colorbar, zrange=[min,max], /zlog, ztitle='Z,units'
 
 KEYWORD PARAMETERS:
       zmat:   supply the z matrix for autoranging. 
       ctable: ctable(0) is first color index, ctable(1) is last.
       ztitle: string to print along axis.
       zrange: like xrange, zrange(0) is first color, zrange(1) is last
       zlog:   logarythmic z axis.
       xpos:   specify position of colorbar relative to the position
               vector x position.  0 is the left edge of plot,

 PROCEDURE:
       locate corners of image, draw tv image. draw axis with "axis"
       procedure.  xyouts zword if specified.

 EXAMPLE:
       hydra_plotcolor, Z, time, energy, $
             zrange=[0.1,100], /zlog, title='POLAR/HYDRA Ions'
       hydra_colorbar, zrange=[0.1,100], /zlog, ztitle='Counts'
