MVLib - Short Writeup - Version 4.0
Example Number 19 - Histogram booking and plotting
This simple example shows how to book and plot an histogram, the calls to mvbook allow to define an histogram, the calls to mvbookfill fille the histogram data structure defined by MVLIb and mvbookplot plot the histograms that can be composed in variety of way. The use of MVLib parameters
  • Histogram Color
  • Histogram Background
  • Histogram Statistic
are also shown.
The source code to produce these plots is available here and the complete script running the code is available here.
