QUESTION:
How to book a 2-D histogram or scatter plot.
ANSWER:
To book a 2-D histo, use the following command:
nameHist = manager->histogram(string, nBins, lowEdge, highEdge, nBins2, lowEdge2, highEdge2);
To fill it, use the command:
nameHist->accumulate2( x, y );
This is the obvious generalisation of the 1-D case.
