'map' object is not subscriptable about django-nvd3 HOT 3 OPEN

This confused me too for a bit when trying to get a demo line chart to work.
Writing here in case it helps someone else who's equally new to all this.

The error I was getting from Django was the same 'map' object is not subscriptable referring to line 220 in my venv's lib/python3.4/site-packages/django_nvd3/templatetags/nvd3_tags.py but that was the symptom not the cause. As Renkai points out above the issue is a python2/3 compatibilty problem in the demo code (not in the nvd3 package), in my case xdata = map(lambda x: start_time + x * 1000000000, xdata) in the demo_linechart function.

Changing it and the similar line beneath to xdata = list(map(lambda x: start_time + x * 1000000000, xdata)) fixed it for me.

Try to change xdata = map(lambda x: start_time + x * 1000000000, xdata) to xdata = list(map(lambda x: start_time + x * 1000000000, xdata)) and so on.

The "list(" should be added in several such places.
Ando more: to get nvd3 working on Python 3.4.2 i changed nvd3_tags.py : unicode to str in 2 places.
Is it possible to make relevant versions to download via pip for Python 2.7 and Python 3 ?
