Bug with data scaling?

Description

I recently switched from 0.2.0 to 0.2.1 and some of my charts are now displaying differently, here is an example:

chart = StackedHorizontalBarChart(270, 20)
chart.set_colours(['fb7e01', 'f8f8f8'])

chart.add_data([50])
chart.add_data([100])

print chart.get_url()

0.2.0 http://chart.apis.google.com/chart?cht=bhs&chs=270x20&chd=s:f,9&chco=fb7e01,f8f8f8

0.2.1 http://chart.apis.google.com/chart?cht=bhs&chs=270x20&chd=s:A,9&chco=fb7e01,f8f8f8

Based on the outputted chart, the 0.2.0 versions produces the intended result. If this is not a data scaling bug, I would appreciate a hint how to achieve the output of the 0.2.0 version with 0.2.1

In 0.2.0, scaling assumed 0 as the lowest value, where 0.2.1+ scaling adjusts to the min and max value of the data given. In your case, 50 is the min and 100 is the max so the range is 50 starting from 50.

If you want to replicate 0.2.0's logic, when creating the graph specify the range values like so:

chart = StackedHorizontalBarChart(270, 50, x_range=[0, 100])

It produces the URL you want.
