### Creating histograms.
histogramFactory = analysisFactory.createHistogramFactory(tree)
### Fixed bin width histogram.
h2dF = histogramFactory.createHistogram2D('fixed', 'Fixed', 20, 0.0, 20.0, 20, 0.0, 20.0)

### Filling with gaussian.
import random
r = random.Random()
for i in range(1000):
	h2dF.fill(r.gauss(10.0, 3.0), r.gauss(10.0, 3.0))

### Plotting the histogram.
plotterFactory = analysisFactory.createPlotterFactory()
plotter = plotterFactory.create('PAIDA Plotter')
plotter.createRegions(2, 2)

plotter.region(0).setTitle('Bar format')
plotter.region(0).style().setParameter('showTitle', 'true')
plotter.region(0).style().dataStyle().setParameter('histogram2DFormat', 'bar')
plotter.region(0).plot(h2dF)

plotter.region(1).setTitle('Box format')
plotter.region(1).style().setParameter('showTitle', 'true')
plotter.region(1).style().dataStyle().setParameter('histogram2DFormat', 'box')
plotter.region(1).plot(h2dF)

plotter.region(2).setTitle('Ellipse format')
plotter.region(2).style().setParameter('showTitle', 'true')
plotter.region(2).style().dataStyle().setParameter('histogram2DFormat', 'ellipse')
plotter.region(2).plot(h2dF)

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