void RegH1F::getHistInfo (  Option_t *  option,
Stat_t &  content,
Stat_t &  error2

void RegH1F::Divide (  TF1 *  f1,
Double_t  c1 = 1
)  [virtual]
 

Divide by a function (as for TH1): this = this/(c1*f1).

Parameters:
f1  The function f1
c1  An optional multiplier to f1

void RegH1F::Divide (  const TH1 *  h1  )  [virtual]
 

Divide by a histogram (as for TH1): this = this/h1.

Parameters:
h1  The histogram h1

Definition at line 181 of file RegH1F.C.

void RegH1F::Divide (  const TH1 *  h1,
const TH1 *  h2,
Double_t  c1 = 1,
Double_t  c2 = 1,
Option_t *  option = 0
)  [virtual]
 

Replace contents by the division of h1 by h2: this = c1*h1/(c2*h2).

Parameters:
h1  The first histogram h1
h2  The second histogram h2
c1  An optional multiplier to h1
c2  An optional multiplier to h2
option  An option. "B" means binomial errors, "S" means subset, i.e. binomial errors for weighted events

Definition at line 185 of file RegH1F.C.

void RegH1F::Divide (  const TH1 *  h1,
const TH1 *  h2,
const TH1 *  h3,
Double_t  c1 = 1,
Double_t  c2 = 1
)  [virtual]
 

Replace contents by the division of h1 by h2, with h3 as overlap histogram: this = c1*h1/(c2*h2).

In the most general case where h1 contains a sum of event weights w_i and h2 a sum of event weights v_i, h3 should contain the sum w_i*v_i for those events which fall into the same x bin; h3 is the overlap histogram.

Parameters:
h1  The first histogram h1
h2  The second histogram h2
h3  The third histogram h3
c1  An optional multiplier to h1
c2  An optional multiplier to h2

void RegH1F::DrawFunc (  Option_t *  option,
const char *  fname
)  [virtual]
 

Enable a specific Fit Function to be plotted with the Histogram.

If the Histogram was fitted with the Option "0", the Fit Function is globally disabled for drawing. This function enables it for the active drawing and disables it again afterwards. Note: The Draw is done via DrawCopy ! Author: Ronnie Weber

Parameters:
option  Draw Options for Histogram
fname  Name of the function
