bar charts

[Jochen Maes]

Hey all,


I'm trying to show 20 baqrs horizontally, and each bar should have a
label, this is the python code:
def create_chart(data, file):
chart = GroupedHorizontalBarChart(300, 300, x_range=(0, 1000000))
chart.set_bar_width(10)
labels = list()
for dat in data[-20:]:
labels.append(dat[0].strip())
chart.add_data([dat[1],])
chart.set_axis_labels(Axis.LEFT, labels)
chart.download('test.png')

here is the result, why do i only see one label?
