Thanks a lot,

it is really a brilliant idea. :)

I have just problem with cgReverseIndices to find indices of avg z values.

here is the code;

readcol, 'sampledata.txt', x, y, z

hist_xy=hist_nd(transpose([[x],[y]]),[0.05,0.05],$
min=[min(x),min(y)],max=[max(x),max(y)],reverse_indices=ri)

avg_hist_xyz=make_array(size(hist_xy,/DIMENSIONS),VALUE=!VAL UES.F_NAN)

for j=0,n_elements(hist_xy)-1 do if ri[j+1] gt ri[j] then $
avg_hist_xyz[j]=mean(z[ri[ri[j]:ri[j+1]-1]])

;;;;;;;;;;;;;;; I am not sure how to use correctly "cgReverseIndices"
indicesz = cgReverseIndices( avg_hist_xyz[ri], 4, COUNT=cnt) ?????
help, indicesz ?????

regards,
Nafiseh
