### Creating histograms.
histogramFactory = analysisFactory.createHistogramFactory(tree)
### Fixed bin width histogram.
h3dF = histogramFactory.createHistogram3D('fixed', 'Fixed', 10, 0.0, 20.0, 10, 0.0, 20.0, 10, 0.0, 20.0)

### Filling with gaussian.
import random
r = random.Random()
for i in range(1000):
	h3dF.fill(r.gauss(10.0, 3.0), r.gauss(10.0, 3.0), r.gauss(10.0, 3.0))

### Plotting the histogram.
plotterFactory = analysisFactory.createPlotterFactory()
plotter = plotterFactory.create('PAIDA Plotter')
region = plotter.createRegion()

region.setTitle('Box format')
region.style().setParameter('showTitle', 'true')
region.style().dataStyle().fillStyle().setColor('blue')
region.plot(h3dF)

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