CellFill: specify cell width?

Hello All,

I have a contour plot of maximum vorticity, vmax(/height,flight leg/).
There are 7 flight legs. What I want is to have the cell width be
representative of the duration of the flight leg, since each flight leg
is not the same time interval. Any I ideas on how to accomplish this?
Or a different approach?

Here are my plot resources:

      res = True
      res@gsnMaximize = True
      res@cnFillOn = True
      res@cnFillMode = "CellFill"
      res@cnLineLabelsOn = True
      res@gsnSpreadColors = True
      res@gsnFrame = False
      res@gsnDraw = False
      res@sfYArray = f->z
      res@tiXAxisString = "Time (UTC)"
      res@tiYAxisString = "Height (km)"
      res@tiXAxisFontHeightF = 0.01
      res@tiYAxisFontHeightF = 0.01
      res@gsnStringFont = "helvetica"
      res@tmYLLabelFontHeightF = 0.0095
      res@tmXBLabelFontHeightF = 0.009
      res@lbOrientation = "Vertical"
      res@tmXBMajorOutwardLengthF = 0.0
      res@tmYLMajorOutwardLengthF = 0.0
      res@tmXBMinorOutwardLengthF = 0.0
      res@tmYLMinorOutwardLengthF = 0.0
      res@cnLabelMasking = True
      res@cnLineLabelBackgroundColor = "transparent"
      res@lbLabelFontHeightF = 0.0075
      res@gsnLeftString = "Vertical Vorticity 10~S~-3~N~ s~S~-1~N~"

      res@tmYLMode = "Explicit"
      res@tmYLValues = fspan(0.45,11.25,19)
      res@tmYLLabels = fspan(0.45,11.25,19)+ " "

      res@tmXBMode = "Explicit"
      res@tmXBValues = ispan(0,6,1)
      ;res@tmXBLabels = (/"Leg0","Leg1","Leg2","Leg3","Leg4","Leg5","Leg6"/)
      res@tmXBLabels = (/"2214:18 -~C~2229:00", \
             "2230:00 -~C~2248:00", \
                         "2250:00 -~C~2305:05", \
                         "2306:00 -~C~2325:00", \
                         "2326:00 -~C~2342:30", \
                         "2344:30 -~C~0001:30", \
                         "0002:45 -~C~0017:30"/)

      res@tiMainString = "Maximum Bookend Vorticity"
      res@gsnSpreadColorStart = 129
      res@gsnSpreadColorEnd = -1
      plot = gsn_csm_contour(wks,vmax,res)
      draw(plot)
      frame(wks)

Thanks,

Phillip
