Class to manage histogram axis.

This class manages histogram axis. It is referenced by TH1 and TGraph. To make a graphical representation of an histogram axis, this class references the TGaxis class. TAxis supports axis with fixed or variable bin sizes. Labels may be associated to individual bins. See examples of various axis representations drawn by class TGaxis.

Execute action corresponding to one event.

This member function is called when an axis is clicked with the locator. The axis range is set between the position where the mouse is pressed and the position where it is released. If the mouse position is outside the current axis range when it is released the axis is unzoomed with the corresponding proportions. Note that the mouse does not need to be in the pad or even canvas when it is released.

Int_t TAxis::FindBin ( const char * label )

virtual

Find bin number with label.

If the List of labels does not exist create it and make the axis alphanumeric If one wants just to add a single label- just call TAxis::SetBinLabel If label is not in the list of labels do the following depending on the bit TAxis::kCanExtend; of the axis.

if the bit is set add the new label and if the number of labels exceeds the number of bins, double the number of bins via TH1::LabelsInflate
if the bit is not set and the histogram has labels in each bin set the bit automatically and consider the histogram as alphanumeric if histogram has only some bins with labels then the histogram is not consider alphanumeric and return -1

-1 is returned only when the Axis has no parent histogram

Double_t TAxis::GetBinCenterLog ( Int_t bin ) const

virtual

Return center of bin in log With a log-equidistant binning for a bin with low and up edges, the mean is : 0.5*(ln low + ln up) i.e.

sqrt(low*up) in logx (e.g. sqrt(10^0*10^2) = 10). Imagine a bin with low=1 and up=100 :

the center in lin is (100-1)/2=50.5
the center in log would be sqrt(1*100)=10 (!=log(50.5))

NB: if the low edge of the bin is negative, the function returns the bin center as computed by TAxis::GetBinCenter

void TAxis::SetTimeFormat ( const char * tformat = "" )

virtual

Change the format used for time plotting.

The format string for date and time use the same options as the one used in the standard strftime C function, i.e. : for date :

     %a abbreviated weekday name
     %b abbreviated month name
     %d day of the month (01-31)
     %m month (01-12)
     %y year without century

for time :

     %H hour (24-hour clock)
     %I hour (12-hour clock)
     %p local equivalent of AM or PM
     %M minute (00-59)
     %S seconds (00-61)
     %% %

This function allows also to define the time offset. It is done via F which should be appended at the end of the format string. The time offset has the following format: 'yyyy-mm-dd hh:mm:ss' Example:

     h = new TH1F("Test","h",3000,0.,200000.);
     h->GetXaxis()->SetTimeDisplay(1);
     h->GetXaxis()->SetTimeFormat("%d\/%m\/%y%F2000-02-28 13:00:01");

This defines the time format being "dd/mm/yy" and the time offset as the February 28th 2003 at 13:00:01

If F is not specified, the time offset used will be the one defined by: gStyle->SetTimeOffset. For example like that:

     TDatime da(2003,02,28,12,00,00);
     gStyle->SetTimeOffset(da.Convert());
