Matplotlib X-axis dates

Show all headers | View raw

Hi Guys

Have been all day looking for a solution on the x-axis and the time plot.

The output that I get is this with all the dates shift to the right overlapping each other. http://postimg.org/image/fs4tx83or/

I want the x-axis to start at 0 and to finish after the 3 entries on the DB.

X Axis should show (and it does but shift one over each other to the right):
2016-06-02 11:15:00
2016-06-02 11:20:00
2016-06-02 11:25:00

Data on the Cassandra DB:
cqlsh:lebara_diameter_codes> select * from nl_lebara_diameter_codes;

country | service | date                            | errorcode2001 | errorcode3056 | errorcode4010 | errorcode4012 | errorcode4998 | errorcode4999 | errorcode5012
---------+---------+---------------------------------+---------------+---------------+---------------+---------------+---------------+---------------+---------------
      NL |    gprs | 2016-06-02 11:15:00.000000+0000 |          3061 |             0 |             1 |             0 |             0 |            50 |           741
      NL |    gprs | 2016-06-02 11:20:00.000000+0000 |          3204 |             0 |             9 |             0 |             0 |            56 |           725
      NL |    gprs | 2016-06-02 11:25:00.000000+0000 |          3044 |             0 |             8 |             0 |             0 |            64 |           722


Code:
sql = country_sql("NL",ago.strftime('%Y-%m-%d %H:%M:%S'),"gprs")
result = sql.sql_statement_range()
for i in result:
        country = i.country
        service = i.service
        x_list.append(i.date)
        code_2001.append(i.errorcode2001)
        code_4012.append(i.errorcode4012)
        code_4998.append(i.errorcode4998)
        code_4999.append(i.errorcode4999)
        code_5012.append(i.errorcode5012)
        code_3056.append(i.errorcode3056)
        code_4010.append(i.errorcode4010)

print(x_list)   --> Output is [datetime.datetime(2016, 6, 2, 11, 15), datetime.datetime(2016, 6, 2, 11, 20), datetime.datetime(2016, 6, 2, 11, 25)]
#date_nump=date2num([i for i in x_list])
date_nump=date2num(x_list)
print(date_nump) --> output is [ 736117.46875     736117.47222222  736117.47569444]
