How to display a line graph in Django?

Hi all, 

I have wrote a python program to display the line graph as follows: 

import matplotlib.pyplot as plt

x = [1,2,3]
y = [2,4,1]
 

plt.plot(x, y)
 

plt.xlabel('x - axis')
plt.ylabel('y - axis')
 

plt.title('My first graph!')
 
plt.show()







Now I need to display the same via Django. So I think I need to write the above code in the view and then redirect the same to the html template file. Am I right?




In that case, how to send the request objects related to the line chart to the template?




Normally, we send in the following format:




def view1(request)


 return render(request, 'display_report.html', { 'var1': "abc", ...
 ... })


So if we are trying to display the line graph generated by the above code, how to do so ? 




Please share your inputs. 




Thanks.

All you need to do is update the render call a dictionary with the customuser variable in it:

return render(request, 'members/member_contact_form.html', {'ContactFormset':ContactFormset, 'Address Formset':AddressFormset, 'customuser': customuser })

Hi,

You need to pass the variables that you want to use in the template to the template itself. You do this here:

return render(request, 'members/member_contact_form.html', {'ContactFormset':ContactFormset, 'AddressFormset':AddressFormset })

The dictionary you add to the render method there contains all the objects that you can get in the template itself. So if you want to add something called object you need to add that to the dictionary.

I have a two formsets rendered in a view called ContactIndex, the parent model for this view is the CustomUser model. I want to present the first_name of the user object in my html template. I've tried these tags without success any advise?

This is the tags in my HTML template:

{{ customuser.first_name }} - does not work

{{ object.first_name }} - does not work

This is my view:

def ContactIndex(request, CustomUser_id):          customuser = CustomUser.objects.get(pk=CustomUser_id)          if request.method == "POST":              ContactFormset = ContactInlineFormSet(request.POST, request.FILES, instance=customuser)              AddressFormset = AddressInlineFormSet(request.POST, request.FILES, instance=customuser)              if ContactFormset.is_valid() or AddressFormset.is_valid():                  AddressFormset.save()                  ContactFormset.save()                  # Do something. Should generally end with a redirect. For example:                  return redirect ('ContactIndex', CustomUser_id=customuser.id)          else:              ContactFormset = ContactInlineFormSet(instance=customuser)              AddressFormset = AddressInlineFormSet(instance=customuser)          return render(request, 'members/member_contact_form.html', {'ContactFormset':ContactFormset, 'Address    Formset':AddressFormset })
