Highstock Demos

Single line series: http://www.highcharts.com/stock/demo/basic-line

This example generates the same highstocks chart as Example1-basic-line.py, but use jsonp_loader from highstock_helper instead of add_data_from_jsonp

jsonp_loader(url, prefix_regex=r'^(.*()', suffix_regex=r'();)$', sub_d=None, sub_by='') jsonp_loader is to request (JSON) data from a server in a different domain (JSONP) and convert to python readable data.

1. url is the url (https) where data is located
2. "prefix_regex" and "suffix_regex" are regex patterns used to 
    remove JSONP specific prefix and suffix, such as callback header: "callback(" and end: ");", 
3. "sub_d" is regex patterns for any unwanted string in loaded json data (will be replaced by sub_by). 
4. "sub_by" is the string to replace any unwanted string defined by sub_d

For function coversion, such as Data.UTC to datetime.datetime, please check JSONPDecoder.
