Could anybody please help me with a simple histogram plot? My code is:
; - Drawing a histogram using discrete bin values
;
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
begin
x = new(32,integer)
do i=0,dimsizes(x)-1
x(i) = i
end do
fl_y_axes="y_zhou.dat"
data_y = asciiread(fl_y_axes,32,"float")
; x_short = x
; qsort(x)
wks = gsn_open_wks("eps","histo") ; open workstation
gsn_define_colormap(wks,"temp1") ; choose colormap
res = True
res@tmXBLabelStride = 2 ; every other x-label
; res@gsnHistogramDiscreteBinValues = ispan(0,31,1)
plot=gsn_histogram(wks,data_y,res)
end
The graph I got is like:
[image:
?ui=2&view=att&th=12744d92ab56da93&attid=0.1&disp=attd&realattid=ii_12744d92ab56da93&zw]
But my data have 32 numbers, I hope thse values are shown as y-axes,
