X axis label in Highcharts graph in Django app - django

I have created Highcharts graph by this code:
def chart_data(request):
dataset = DispatchPlan.objects.annotate(month=TruncMonth('scheduled_date')).values('month').annotate(
c=Sum('weight')).values('month', 'c')
chart = {
'chart': {'type': 'column'},
'title': {'text': 'Weight Dispatched by Months'},
'series': [{
'name': 'Months',
'data': [{'name': row['month'], 'y': row["c"]} for row in dataset]
}]
}
return JsonResponse(chart)
How can I add the X axis labels such that it shows month name instead of 0 and 1 ?
This is the one row of dataset from which the graph is plotted
{'month': datetime.datetime(2019, 6, 1, 0, 0, tzinfo=<DstTzInfo 'Asia/Kolkata' IST+5:30:00 STD>), 'c': 17600}


Try to use strftime (documentation) like that :
{'month': datetime.datetime(2019, 6, 1, 0, 0, tzinfo=<DstTzInfo 'Asia/Kolkata' IST+5:30:00 STD>).strftime("%B"), 'c': 17600}

How can I add multiple object references of a class to a list in flutter?

I have some object references of a class like this:
Patient patientOne = Patient('Person A', 'https://images.unsplash.com/photo-1545996124-0501ebae84d0?ixid=MXwxMjA3fDB8MHxzZWFyY2h8OHx8aHVtYW58ZW58MHx8MHw%3D&ixlib=rb-1.2.1&w=1000&q=80',
8, 2, 'Pending', '10-08-2015', true);
Patient patientTwo = Patient('Person B', 'https://images.unsplash.com/photo-1544005313-94ddf0286df2?ixid=MXwxMjA3fDB8MHxzZWFyY2h8MTF8fGh1bWFufGVufDB8fDB8&ixlib=rb-1.2.1&w=1000&q=80',
8, 5, 'Cancel', '23-12-2019', false);
Patient patientThree = Patient('Person C', 'https://images.unsplash.com/photo-1554151228-14d9def656e4?ixid=MXwxMjA3fDB8MHxzZWFyY2h8NHx8aHVtYW58ZW58MHx8MHw%3D&ixlib=rb-1.2.1&w=1000&q=80',
8, 7, 'Cancel', '01-02-2019', false);
Patient patientFour = Patient('Person D', 'https://upload.wikimedia.org/wikipedia/commons/e/ec/Woman_7.jpg',
8, 4, 'Pending', '20-09-2018', true);
Patient patientFive = Patient('Person E', 'https://cdn.pixabay.com/photo/2017/08/07/14/15/portrait-2604283__340.jpg',
8, 6, 'Pending', '28-04-2017', false);
I want to store those reference variables (patientOne , patientTwo ... patientFive ) into a list.
How to do that ?

final List<Patient> patients = <Patient>[];
patients.addAll([patientOne,patientTwo,patientThree,...]);
or
final List<Patient> patients = [
Patient('Person A', 'https://images.unsplash.com/photo-1545996124-0501ebae84d0?ixid=MXwxMjA3fDB8MHxzZWFyY2h8OHx8aHVtYW58ZW58MHx8MHw%3D&ixlib=rb-1.2.1&w=1000&q=80',

8, 2, 'Pending', '10-08-2015', true)

How to define last row in xlsxwriter while using add_chart

I running a script to take rows and columns from a worksheet and use it to make charts. The problem that I am running into is that since the rows in the MSEXCEL sheet are changing, I want to add the last row in the add_series argument so that it will always take the limit of the chart data from row 2 till the last row.
This is the code that I am using currently (that I want to change):
chart1 = workbook.add_chart({'type': 'column'})
chart1.add_series({
'values': "='Sheet1'!$B$2:$B$126",
'categories': "='Sheet1'!$A$2:$A$126",
'data_labels': {'value': False, 'categories': False, 'series': False}
})
I have modified the above code to the following, but now the charts are not getting any data whatsoever.
chart1 = workbook.add_chart({'type': 'column'})
chart1.add_series({
'values': "='Sheet1'!$B$2:($B$ + str(last_row_number + 1)",
'categories': "='Sheet1'!$A$2:($A$ + str(last_row_number + 1)",
'data_labels': {'value': False, 'categories': True, 'series': False}
last_row_number in this case is a variable [<type 'int'>] calculated by enumerating through the worksheet column.
Thanks in advance.

Almost every interface in XlsxWriter supports (row, col) notation as well as A1 range notation.
In the case of add_series() you can use lists like [sheetname, first_row, first_col, last_row, last_col]:
chart.add_series({
'categories': ['Sheet1', 1, 0, 125, 0],
'values': ['Sheet1', 1, 1, 125, 1],
# ...
})
# Or:
last_row = 125
chart.add_series({
'categories': ['Sheet1', 1, 0, last_row, 0],
'values': ['Sheet1', 1, 1, last_row, 1],
# ...
})
See the docs for add_series().

Plotting multiple pie charts in plotly

I have the following code from edited from: How to plot pie charts as subplots with custom size with Plotly in Python
import plotly
import plotly.offline as py
import plotly.graph_objs as go
py.init_notebook_mode(connected=True)
labels = ['Oxygen','Hydrogen','Carbon_Dioxide','Nitrogen']
values = [4500,2500,1053,500]
domains = [
{'x': [0.0, 0.33], 'y': [0.0, 0.50]},
{'x': [0.33, 0.66], 'y': [0.0, 0.50]},
{'x': [0.66, 1], 'y': [0.0, 0.50]},
{'x': [0.0, 0.33], 'y': [0.50, 1]},
{'x': [0.33, 0.66], 'y': [0.50, 1]},
{'x': [0.66, 1], 'y': [0.50, 1]},
]
traces = []
valueslist = []
for domain in domains:
trace = go.Pie(labels = labels,
values = values,
domain = domain)
traces.append(trace)
layout = go.Layout(height = 600,
width = 600,
autosize = False,
title = 'Main title')
fig = go.Figure(data = traces, layout = layout)
py.iplot(fig, show_link = False, image='png')
I am trying to plot 6 pie charts at one time with different values and different titles for each chart. How should I add these extra lists? Assume, I have the following lists to add:
values1 = [5, 6, 1, 2]
values2 = [1, 4, 5, 6]
values3 = [2, 6, 2, 4]
values4 = [1, 5, 3, 7]
values5 = [25, 51, 33, 47]
#with following titles:
title = 'title0'
title1 = 'title1'
title2 = 'title2'
title3 = 'title3'
title4 = 'title4'
title5 = 'title5'

Data structure in Python

names=['Peter', 'John']
size = ['X', 'M', 'L']
list_price = [1, 2, 3, 4, 5, 6] # There are 2 people will buy 3 size of shirt
I want to create my data structure into:
[
{'name': u'Peter', 'size_price': defaultdict(<type 'int'>, { 'X': 1, 'M':2, 'L': 3})},
{'name': 'John', 'size_price': defaultdict(<type 'int'>, {'X':4, 'M':5, 'L':6})}
]
I prefer to do defaultdict()

You can turn list_price into an iterator and then use next to get one value after the other:
>>> iterator = iter(list_price)
>>> [{"name": n, "size_price": {s: next(iterator) for s in size}} for n in names]
[{'size_price': {'X': 1, 'M': 2, 'L': 3}, 'name': 'Peter'},
{'size_price': {'X': 4, 'M': 5, 'L': 6}, 'name': 'John'}]
Of course you do not have to use a list comprehension but can do the same thing with nested loops as well.

Manually rendering django template with date filter

I've got the template to render manually, but not the dates with a filter. Is there a way of doing this without formatting the dates before I put them in the context?
Here is the code:
t= This is to notify you that you are booked on the course {{title}} that starts on {{start_date|date:"F j, Y"}} at {{start|time}} and is being held at {{venue}}.
c = {'startdate': datetime.datetime(2010, 12, 1, 9, 0), 'enddate': datetime.datetime(2010, 12, 1, 12, 0), 'has_cpd': False, 'title': 'Course 1', 'closes': None, 'creator': 1L, 'venue': 'Venue for Course 1', 'summary': 'Course 1 Summary', 'tags': '', 'attachment': <FieldFile: None>, 'organiser': 3L, 'id': 1L, 'opens': datetime.datetime(2010, 11, 30, 20, 1, 50, 951490), 'venue_map': None}
t.render(c)
This gives the output:
This is to notify you that you are booked on the course Course 1 that starts on at and is being held at Venue for Course 1.
Why don't the dates show up?

Looks like a simple typo between start_date vs. startdate.
In [18]: t= Template("""This is to notify you that you are booked on the course {{title}} that starts on {{startdate|date:"F j, Y"}} at {{start|time}} and is being held at {{venue}}.""")
In [19]: t.render(c)Out[19]: u'This is to notify you that you are booked on the course Course 1 that starts on December 1, 2010 at and is being held at Venue for Course 1.'
