AIDA provides two different kinds of histograms: binned and unbinned.
Binned histograms are called IHistogram1D, IHistogram2D, IHistogram3D for one, two and three-dimensional histograms.
Similarly, unbinned histograms are called ICloud1D, ICloud2D, ICloud3D
Getting started
Viewing and Loading Plots
Lets start with viewing AIDA objects. You can either create them with the AIDA examples, the org.lcsim examples or you can load an existing AIDA file with File->Open File... in the menu.
All AIDA objects are arranged in trees. You can have many trees open at the same time; they are represented as Folders, 
. Trees can contain, e.g. Clouds 
and/or Histograms 
, with the name of the object appearing next to it. If a folder is closed, double-clicking will open it and display its contents. Similarly, double-clicking on an open folder will close it, so that the contents are hidden.

Trees that are created by the org.lsim examples will have non-descriptive names like |
A double-click on a Cloud or a Histogram will cause JAS3 to plot the contents.

If you want to display more than one plot on a page, you have to use the context menu.
