### In AIDA system, an analysisFactory creates some treeFactories,
### and a treeFactory creates some trees.
analysisFactory = IAnalysisFactory.create()
treeFactory = analysisFactory.createTreeFactory()
tree = treeFactory.create()
### The tree with zipped XML format and allowing to create new r/w mode file.
#tree = treeFactory.create('exampleBasic.aida', 'xml', False, True, 'compress=yes')

### Creating a histogram.
histogramFactory = analysisFactory.createHistogramFactory(tree)
h1d = histogramFactory.createHistogram1D('name', 'title', 20, 0.0, 20.0)

### Filling with gaussian.
import random
r = random.Random()
for i in range(1000):
	h1d.fill(r.gauss(10.0, 3.0))

### Plotting the histogram.
### analysisFactory -> plotterFactory -> plotter -> region(s)
plotterFactory = analysisFactory.createPlotterFactory()
plotter = plotterFactory.create('PAIDA Plotter')
region = plotter.createRegion()
region.plot(h1d)

### Save plots to a file.
plotter.writeToFile('sampleBasic.ps')

### Wait.
dummy = raw_input('Hit any key.')
