Chart from dictionary/date source ?

[Julien42]

Hello,

I'm new to python google chart and while I search the web for an answer, I didn't find any answer so ask it here.

I'm recovering a dataset in a dictionary array in the form

results['status1'] = [ datetime1, datetime2, datetime3, .... ]

results['status2'] = [ datetime1, datetime2, datetime3, .... ]

What I'm looking for is to make a chart like bar which for each day, give counts of corresponding entries (eventually, do it per hour or per week)

I try to start with the code from

https://github.com/perrygeo/perrygeo.github.com/blob/master/_posts/2007-12-19-more-on-google-charts-and-a-python-interface.markdown

and it fails like this

>>>

  File "/home/user/script/script-chart.py", line 383, in plot_googlechart

    url = chart.get_url()

  File "/usr/lib/pymodules/python2.7/pygooglechart.py", line 342, in get_url

    url_bits = self.get_url_bits(data_class=data_class)

  File "/usr/lib/pymodules/python2.7/pygooglechart.py", line 350, in get_url_bits

    url_bits.append(self.data_to_url(data_class=data_class))

  File "/usr/lib/pymodules/python2.7/pygooglechart.py", line 609, in data_to_url

    data = self.scaled_data(data_class, self.x_range, self.y_range)

  File "/usr/lib/pymodules/python2.7/pygooglechart.py", line 576, in scaled_data

    y_range = self.data_y_range()

  File "/usr/lib/pymodules/python2.7/pygooglechart.py", line 546, in data_y_range

    if type == 'y'])

TypeError: cannot concatenate 'str' and 'int' objects

<<<

but I'm not really sure which format should have input data. Any hints ?

Eventually at the end, I want to add to the end of the chart data like

results['status1'] = [ datetime1, datetime2, datetime3, ...., 'invalid', 'unknown' ]

Thanks a lot.

Cheers,

Julien
