Draw expression varexp for specified entries.
varexp is an expression of the general form e1:e2:e3 where e1,etc is a C++ expression referencing a combination of the TTable columns One can use two extra meta variable "i$" and "n$" along with the table column names. i$ is to involve the current row number n$ refers the total num,ber of rows of this table provided by TTable::GetNRows()
Example: varexp = x simplest case: draw a 1-Dim distribution of column named x = sqrt(x) : draw distribution of sqrt(x) = x*y/z = y:sqrt(x) 2-Dim dsitribution of y versus sqrt(x) = i$:sqrt(x) 2-Dim dsitribution of i versus sqrt(x[i]) = phep[0]:sqrt(phep[3]) 2-Dim dsitribution of phep[0] versus sqrt(phep[3])
Note that the variables e1, e2 or e3 may contain a boolean expression as well. example, if e1= x*(y<0), the value histogrammed will be x if y<0 and will be 0 otherwise.
selection is a C++ expression with a combination of the columns. The value corresponding to the selection expression is used as a weight to fill the histogram. If the expression includes only boolean operations, the result is 0 or 1. If the result is 0, the histogram is not filled. In general, the expression may be of the form:
value*(boolean expression)
if boolean expression is true, the histogram is filled with a weight = value. Examples: selection1 = "x<y && sqrt(z)>3.2 && 6 < i$ && i$ < n$" selection2 = "(x+y)*(sqrt(z)>3.2" selection3 = "signal*(log(signal)>1.2)" selection1 returns a weigth = 0 or 1 selection2 returns a weight = x+y if sqrt(z)>3.2 returns a weight = 0 otherwise. selection3 returns a weight = signal if log(signal)>1.2
option is the drawing option see TH1::Draw for the list of all drawing options. If option contains the string "goff", no graphics is generated.
nentries is the number of entries to process (default is all) first is the first entry to process (default is 0)
By default the temporary histogram created is called htemp. If varexp0 contains >>hnew (following the variable(s) name(s), the new histogram created is called hnew and it is kept in the current directory. Example: tree.Draw("sqrt(x)>>hsqrt","y>0") will draw sqrt(x) and save the histogram as "hsqrt" in the current directory.
By default, the specified histogram is reset. To continue to append data to an existing histogram, use "+" in front of the histogram name; table.Draw("sqrt(x)>>+hsqrt","y>0") will not reset hsqrt, but will continue filling.
In case of a 2-Dim expression, one can generate a TProfile histogram instead of a TH2F histogram by specyfying option=prof or option=profs. The option=prof is automatically selected in case of y:x>>pf where pf is an existing TProfile histogram.
TTable::Draw can be used to fill a TEventList object (list of entry numbers) instead of histogramming one variable. If varexp0 has the form >>elist , a TEventList object named "elist" is created in the current directory. elist will contain the list of entry numbers satisfying the current selection. Example: tree.Draw(">>yplus","y>0") will create a TEventList object named "yplus" in the current directory. In an interactive session, one can type (after TTable::Draw) yplus.Print("all") to print the list of entry numbers in the list.
By default, the specified entry list is reset. To continue to append data to an existing list, use "+" in front of the list name; table.Draw(">>+yplus","y>0") will not reset yplus, but will enter the selected entries at the end of the existing list.

Fit a projected item(s) from a TTable.
formula is a TF1 expression.
See TTable::Draw for explanations of the other parameters.
By default the temporary histogram created is called htemp. If varexp contains >>hnew , the new histogram created is called hnew and it is kept in the current directory. Example: table.Fit(pol4,"sqrt(x)>>hsqrt","y>0") will fit sqrt(x) and save the histogram as "hsqrt" in the current directory.
