I am having problem while displaying graphs with django-graphos. I have tried according to the documentation.its not showing the site names in the x-axis and also no plots on the graph :

my code :

models.py

    class MonthlySiteResponse(models.Model):

        site_name     = models.CharField(max_length=30)
        response_time = models.FloatField()

views.py

    def fn(request) :

        site_response_details = {'Site A' : 1.864, 'Site B' : 2.086, 'Site C' : 2.873, 'Site D' : 2.22 }


        #Saving data in my model fields
        for name, value in site_response.items() :
            new = MonthlySiteResponse()
            new.site_name = name
            new.response_time = value
            new.save()

        queryset = MonthlySiteResponse.objects.all()
        data_source = ModelDataSource(queryset, fields= ['site_name', 'response_time'])

        chart = flot.BarChart(data_source, options={'title': "Website"})

        return render_to_response("graphs.html", {"chart": chart})

graph.html

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        {% load static %}
        <script type="text/javascript" src="{% get_static_prefix %}js/jquery.js"></script>
        <script src="{% get_static_prefix %}js/flot/jquery.flot.js" type="text/javascript"></script>
        <script src="{% get_static_prefix %}js/flot/jquery.flot.categories.js" type="text/javascript"></script>

    </head>

    <body>
        {{chart.as_html}}
    </body>
    </html>

Can anyone suggest any other package to be used with Django models queryset?

回答1:

I don't know anything about Django-graphos, so this is a WAG, but try:

 chart = flot.BarChart(data_source, options={'title': "Website", 'xaxis': {'mode': "categories"}})

回答2:

What platform are you trying this on ? Have you tried running the demo site from graphos available on github ?

to run the Demo site

go to/django-graphos/demo_project/demo_project/settings/
$cp local.py-dist local.py
Change your directory to /django-graphos/demo_project/
$pip install -r requirements.txt
run the local server by going to go to /django-graphos/demo_project/
$python manage.py runserver
check the demo by visiting localhost:8000 in your browser.

This will give you fairly good idea how Django-graphos can be used, if you face any issues do ask.
