ELL_PLOT_SEG

ELL_PLOT_SEG

Name


      ELL_PLOT_SEG

Purpose


      Plot a color coded data segment on current map.

Category


Calling Sequence


      ell_plot_seg, p1, p2

Inputs


      p1 = Start of segment to plot. in
      p2 = Endpoint of segment to plot. in
        Both points are structures {lon:lon,lat:lat}.

Keyword Parameters


Keywords


        COLOR=clr Array of 24-bit colors of data along segment.
        WIDTH=wd Width of segment in meters.
        NUM=num Number of steps across width.

Outputs


Common Blocks


Notes


      Notes: If plotted color band has holes trying using
        thick=2 (or 3).
        Assumes data values (given by the clr array) are evenly
          spaced in range from pt1 to pt2.

Example


          map_set,39,-77,scale=4e6,/cont,/usa
          x1=-80 & y1=37
          x2=-73 & y2=41
          v = makey(500)*50-75
          clr=color_code(v)
          ell_plot_seg,{lon:x1,lat:y1},{lon:x2,lat:y2},color=clr, $
            width=10000,num=100,thick=2
          map_set,39,-77,scale=4e6,/cont,/usa,/noerase
