Re: x axis Major Tick Marks

Hello,

    I got the tick marks and labeling on x axis. I found that the commands
in my script have to set res@tmXBMode = "Manual", but
"warning:ManualComputeMajorTickMarks: The precision specified is smaller
than the precision needed tick mark labels may not be correct" still showed
up though tmXBLabels and tmXBTickStartF are consistent. I am not sure what
the warning means. Tingting's commands can be used in res@tmXBMode =
"Manual" or "Explicit" without any warning. But, I only need years on x
axis.

########## my version
  res@tmXBMode = "Manual"
  res@tmXBValues = ispan(1,36,1) ;1986-1988, 3yrs, 36mos
  res@tmXBLabels = mth
  res@tmXBTickStartF = 1986
  res@tmXBTickEndF = 1989
  res@tmXBTickSpacingF= 1
  res@tmXBPrecision = 4

########## Tingting's version
  yyyymm = yyyymm_time(1996, 1998, "integer")
  yrfrac = yyyymm_to_yyyyfrac(yyyymm, 0.0)
  res@trXMinF = 1986
  res@trXMaxF = 1989
  res@tmXBMode = "Explicit"
  res@tmXBValues = yrfrac
  res@tmXBLabels = ""+yyyymm

  res@tmXBLabelAngleF = 60
  res@tmXBLabelFontHeightF = 0.008

    Best,
