 Hi ROOTers,

This is the link to a page from PAW manual :

http://ncdf68.fnal.gov/~litvinse/sets.jpg


 This is a graphic explanation of all relevant setting parameters.

 suggestion:
         I am really missing such a picture in ROOT manual. Could you
	 consider adding similar picture to it?

 question 1:
         how can I set the width of the histogram frame from the command
         prompt?

         Is where TStyle setter that controls this width that can be
         set once for the whole session?

 question 2:
         How one changes the precision format of the numbers shown
         in stat box or fit box of the histogram? How can it be set to
         scientific format for example.

 problem:
         If I plotted a histogram and then superimposed another
         histogram on the top of it such that the latter has some
         solid FillColor set, the tick marks on axes get obscured.
         This is very inconvenient. I think in PAW one could just
         redraw the first histogram once again with S option to recover
         ticks or at least there was some such trick. In ROOT am able
         to come up with the only solution of plotting filled histogram
         first and then superimposing unfilled one on the top of it,
         then ticks are OK, but this method does not work if you have
         several filled histograms.
         (once could also create axes separately and plot
         them on the top of the picture, but this is very tedious).

 regards,
 Dmitri Litvintsev
