Hello,
I have rectified the positioning by correcting the defined positions 1 & 2.
position1 = [0.15, 0.40, 0.95, 0.90]
position2 = [0.15, 0.10, 0.95, 0.30]
I see 'sky blue' color applied to the background for the error-estimate plot. I want the area covering lower_error and high_error be represented in 'sky blue' color. What is going wrong? I don't see any extreme standard deviations in my data (i.e., the standard deviations are always less than corresponding mean values). I have replaced the lines for box / bar plot to make as line plot.
I have changed the statements in the code as below:
!P.Multi=[0,1,2]
; Draw the first plot
cgPlot, xtime, var_data, Title=title, XTitle=xtitle, YTitle=ytitle1, $
XStyle=8, Position=position1,/NoData, YRange=[0,900], $
XRange=[86.0, 88.0], YStyle=1
; Fill in the error estimates
cgColorFill, [xtime, Reverse(xtime), xtime[0]], $
[high_error, Reverse(low_error), high_error[0]], $
Color=colors[1], Position=position1
; Draw the line plot with no data
cgPlot, xtime, var_data, linestyle=0, thick=2,Color=colors[3],/OVERPLOT
cgPlot, xtime, var_min, linestyle=2, thick=2, Color=colors[2],/OVERPLOT
cgPlot, xtime, var_max, linestyle=2, thick=2, Color=colors[2],/OVERPLOT
; Draw the bottom plot without a top axis
cgPlot, xtime, npoints, PSYM=16, Color=colors[0], $
SYMSIZE=0.5,Position=position2, $
YTitle=ytitle2, XTitle=xtitle, XRange=[86.0,88.0], YRange=[0,100]
; Clean up.
!P.Multi = 0
Please suggest...
Thanks in advance.

My intention was to obtain: (1) top panel plot - Error estimation plot with mean, standard deviation as background and min-max as boundaries for a time-series data of a variable, (2) below panel plot - Bar plot showing the frequency of observations respectively at each time-step corresponding to the above plot. I started using the examples of colored line plots (for two row plotting), Error-estimate

I got an error for bar plot as "CgAxis - Keyword array parameter XTICKNAME must have from 1 to 60 elements". I don't have any clue where I am actually going wrong, probably I have not understood properly the Coyote's library graphic routines. Can someone provide me assistance to achieve my desired plot?
