More simple questions. I tried duplicating what i found in the online
TClonesArray, and i looked in the user's guide, but my code still
won't run properly :( so i tried and RTFM...
(root 5.13.04, windows 2000, compiliing with msvc 8)
all i want is 8 identical histograms to fill and reference in an array.
"
TClonesArray bigArr("TH1F", 8);
for (chan=0; chan<NUM_CHAN; chan++) { new(bigArr[chan]) TH1F(name,title,HIST_SIZE,0,HIST_SIZE); printf("\t after%d\n\n",chan); } [fill histograms, read histograms, write histograms]
the program doesn't crash, but when I try to fill the histograms with a simple parabolic pattern, every getbincontent(x) returns 0.
When i try to write either the bigArr[x] or just bigArr nothing gets into the file that i try to write to (eg i open in Cint and do f1.ls() and it shows an empty file).
I tried making the new commands not inside of a block (that is, i wrote in chan=0 new().... with no loop) to see if that would change anything and it didn't.
I must be initializing things wrong.
Thanks Again,
George
