BARCHR plots a bar chart with optionally shaded bar segments and descriptive legends. In addition, multiple lines with shading between lines can be plotted. Legend can be automatically placed or the user can specify the location of the legend. In the bar chart mode, bars can run vertically or horizontally. b(i,j) specifies the ith bar and jth segment of bar (or horizontal line depending on iflag option). Top of jth segment or height of jth line is computed from:
j
yplotted = ylen * (Sum b(i,k) - bm)/(bx-bm)
k=1
