Hi Krzysztof,
>From a TBrowser, you can draw several histograms in the same pad.
 -Divide your pad (eg with the canvas context menu).
 -click on any pad with teh middle mouse button to set the current pad.
 -double click on the histogram in the browser

TBrowser supports the selection of multiple objects, but this
information
is currently not used by the other Root classes.
