- A multiple bar graph contains comparisons of two or more categories or bars.
- One axis represents a quantity and the other axis identifies a specific feature
- about the categories. Reading a multiple bar graph includes looking at extremes
- (tallest/longest vs. shortest) in each grouping.
- Python example::
- from nvd3 import multiBarChart
- chart = multiBarChart(width=500, height=400, x_axis_format=None)
- xdata = ['one', 'two', 'three', 'four']
- ydata1 = [6, 12, 9, 16]

- chart.add_serie(name="Serie 1", y=ydata1, x=xdata)
