i have to make java program, which have to create Histogram, and it have to be opened with IE (internet explorer )
The method is final/Static or graph creation.
It's just simple two arrows (X and Y ), and some rectangular (like 3-6 of them)
Like this one:
So, can some body help me with code, because i have no idea how to make it ...
( in fact, just one person of 22 made this graph  )

Does the program need to run in IE? Or just have the image run in IE?
How is the graph data stored?
