Re: Creating dynamic chart / graphs with Django

[Ryan Nowakowski]

I like to start with one of the free dashboard templates for a project like 
this. I've used both CoreUI and AdminLTE in the past with good success. These 
dashboard templates include some sample graphs using one of the standard 
JavaScript charting libraries. 

I look at these graph examples for how the data is loaded. Then I use Django to 
load the data that same way. I like to optimize the data on the back end 
instead of having the charting library optimize it on the front end. For 
example, I'll do the interpolation of data in Python on the back end.

This allows me to have a project that has a pretty nice looking feel by 
default. Also I don't have to go through the trouble of trying to select a 
front end stack. The template has already done that for me.

Re: Creating dynamic chart / graphs with Django

[Thomas Lockhart]

Django integration is fairly easy with Bokeh. For very large datasets you will 
want to also use Datashader and Holoviews so that high-density data gets 
rendered with meaningful interpolations.

Re: Creating dynamic chart / graphs with Django

[Santhosh Kumar]

i too have similar requirement. I tried plotly, however the integration of 
django and plotly didnt go well often with huge data in sense, loading time 
was high and special channels setup was required. (i learnt from this video 
).
Currently im trying with chartjs.
Any other better suggestions please let us know in the group.

I believe (not sure) such channels implementation will be required for 
bokeh and seaborn as well.

Plus, in order to be an interactive real "live" chart you can use ajax.

Creating dynamic chart / graphs with Django

[tristant]

I am looking to build site with a variety of charts and graphs. A quick 
search shows quite a lot of packages out there, as listed here Django 
Packages : Charts 

Has anyone used any of these packages and could provide some advice on 
which is better? For my task, I am looking to create both typical 2D charts 
as well as possible 3D plots. The charts need to be interactive ( as in 
user can tweak inputs and expect the charts to respond).

I have done similar charts with R Shiny. I am wondering which of these 
packages can do similar things?

I notice in the link, some packages mention "offline". Does this mean they 
cannot create interactive charts?

Thanks.

USING graphs in django admin

[Luvpreet Singh]

I want to display graphs in django admin. Is there any tool to display them 
in django admin site ? 


I have tried django-admin-tools-stat , but I don't want to create a 
different dashboard for the graphs.


I want the queries on the models to be displayed with the help of those 
graphs.

Re: Graphs in django

[Anoop Thomas Mathew]

Hi,

What you are generating right now, is in a GTK window (desktop). This is
not directly show-able in a browser AFIK. What you can do is to
1. Generate a jpeg/png from that, and serve it as a static file to the
browser, just like an image
2. You can send the data across to the browser as json or any other
serialized format, and plot it using a javascript plotting library like
flot or flotr2 . This option would make
it more maintainable, look nicer and interactive.
Hope I am clear to you.

Thanks and Regards,
Anoop Thomas Mathew

Re: Graphs and django

[Ben Ford]

Hey Toby,
Thanks for the input, I'll try these things on tuesday (not to make anyone
jealous but I'm going to Bali for a long weekend in about 10 minutes :-D ).
The problems came up when I followed the steps in one of your .txt files...
I haven't had a chance to rigorously explore whats going on yet, and I'll
get right on to that when I get back!
As (another) aside I'm developing a reporting framework for django at the
moment, which I'd be keen to release to the community, and I think something
like dataplot would be a really good partner to that!! I'll be in touch -
sunburn not withstanding - when I get back! :-)

Re: Graphs and django

[Toby Dylan Hocking]

Hey Jeremy,

Thanks for the input. You are correct: I am running a recent copy of 
django from SVN on the primary machine I am using to develop 
django.contrib.dataplot.

In fact, I ran into the same problem that you did when I tried to port 
django.contrib.dataplot to a different machine -- a machine running Django 
0.95. After realizing the existence of the new backwards-incompatible 
changes, I was able to get the django.contrib.dataplot.bike demo app 
working on my old system by simply adding the max_digits and 
decimal_places arguments to the bike/models.py FloatFields. Another 
solution would have been to upgrade the django libraries to the new trunk 
versions.

Again, thanks for trying out my library. I'm anxious to hear if you're 
able to get it working. Once you are able to get the bike app working on 
your system, it should be straightforward to translate the design 
paradigms to your plotting application.

Sincerely,
Toby Dylan Hocking

Re: Graphs and django

[Toby Dylan Hocking]

Hi Ben,

I see what you're doing now. There are a couple things I should mention.

First of all, you are right: getattr(r,'generic.scatter.plot') is not the 
same as typing r.generic.scatter.plot -- instead, it invokes the 
__getattr__ method of r, and looks for something by that name in the R 
namespace. Having found nothing, it raises an exception. If it did find 
something -- you'd have to rplot.source_for_function() or 
r.source("/path/to/generic.scatter.plot.R") first -- it would return the 
function, and assign it to r.generic_scatter_plot (rpy automatically 
translates R dots . to python underscores _ in variable names).

It also looks like our package versions are significantly different. RPy 
is notoriously touchy about what particular package versions you are 
using, so that may be the cause of django.contrib.dataplot's failure on 
your system. But despite the differences in package versions, I bet that 
if you source the R code first, you will be able to execute the getattr 
properly, i.e.

>>> from rpy import r
>>> r.source("/usr/local/lib/python2.4/site-packages/django/contrib/dataplot/R/generic.scatter.plot.R")
{'visible': False, 'value': }
>>> r.generic_scatter_plot


However, the whole point of django.contrib.dataplot is that it takes care 
of these details for you ---

>>> from django.contrib import dataplot
>>> plot=dataplot.Scatter('myscatterplot',fun_to_get_scatter_data)
>>> plot.to_html()

Have you tried to get the demo bike app (django.contrib.dataplot.bike) to 
work? If you are able to get those simple examples working, it should be 
straightforward to translate the design paradigm to your problems.

Sincerely,
Toby Dylan Hocking

Hi Toby,
My versions are:
R:2.4.0
Python:   2.5.1
Rpy:1.0-RC2

Sorry I wasn't very clear earlier... I imported r into ipython to have a
play with it and see what happens. I tried getattr(r,' generic.scatter.plot')
which didn't work - I'm under the impression that getattr won't work with
dotted notation like that if you're doing normal object lookup, am I right
in saying that r does it differently to python? So i tried getattr(r,
'generic') and that didn't work either. The error I get is:
> Error in get(x, envir, mode, inherits) : variable "generic.time.series"
was not found
I tried it with underscores too and I got exactly the same message...

In fact just having looked through the source and having a play with rpy it
seems that there are bugs all over the place:

>>> from rpy import r
RHOME= /usr/lib/R
RVERSION= 2.4.0
RVER= 2040
RUSER= /home/ben
Loading Rpy version 2040 .. Done.
Creating the R object 'r' ..  Done
>>> r
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python2.5/site-packages/rpy.py", line 307, in __repr__
Rver = self.__getitem__('R_version_string')
  File "/usr/lib/python2.5/site-packages/rpy.py", line 290, in __getitem__
obj = self.__dict__[name] = self.__dict__.get(name, self.get(name))
rpy.RException: Error in get(x, envir, mode, inherits) : variable
"R_version_string" was not found

It looks like the logic in R.__getattr__ isn't working properly! I'll
reinstall it at some point and see how it works :-)

After linking dataplot into my contribs dir and adding both dataplot
and dataplot.bike in my INSTALLED_APPS, I get this:

Error: Couldn't install apps, because there were errors in one or more models:

A quick check indicates that this is because of a backwards incompat in Django:
http://code.djangoproject.com/wiki/BackwardsIncompatibleChanges#RenamedFloatFieldtoDecimalField

I guess you're running on latest trunk?

Re: Graphs and django

[Toby Dylan Hocking]

Hi Ben,

I'm excited to hear that you got a copy of django.contrib.dataplot and you 
are trying it out. I will try to help you debug the problem, but the 
full traceback may be more useful. Can you send it?

The purpose of the get_r_fun method is to look at the current R 
environment and check if the desired R function has been source'ed yet. 
This is one of the first steps before passing the data before R.

I take the "r has no attribute generic" to refer to one of the generic 
plotting functions named in one of the RPlot subclasses -- you must be 
dealing with Scatter, TimeSeries, or NormalQQPlot, right? Are you sure it 
doesn't say something like "r has no attribute generic.scatter.plot"? You 
might try changing the dots . to underscores _ in the 
r_fun_name='generic.scatter.plot' line in the definition of the 
ScatterPlot subclass.

Maybe your version of RPy isn't translating python names into R names the 
same way as mine is? I'm using RPy 0.4.6-3ubuntu2 Python 2.4.2-0ubuntu3 
and R 2.2.1-2 on ubuntu dapper. What are your versions?

Sincerely,
Toby Dylan Hocking

Basically it is an interface to the R programming language (for statistics 
and graphics) through the RPy package. You can download my latest release:

I'm a statistician who has been using this system for some time at my

for general use with the Django framework.

The installation instructions are in INSTALL.txt in the archive. 
Documentation is mostly present in docstrings at the moment -- I'm working

I had a similar experience with matplotlib. The docs are not always too 
easy to understand so you have to do some digging and experimenting but 
it is very flexible  and powerful and the resulting charts are good quality.

A recipe here shows how to return a matplotlib image in a Django response:

One fast way for line graphs would be plain PIL
(http://www.pythonware.com/products/pil/) module. But the results are
usually not really pretty: No antialiasing of lines, except you also use
the aggdraw module (http://effbot.org/zone/aggdraw-index.htm).

If you want do do really nice graphs, you might take a look at some
screenshots of matplotlib:
http://matplotlib.sourceforge.net/screenshots.html

The module is quite large, but has really many functions: from simple
pie charts (3D too) up to finance charts which gets data from
finance.yahoo.com

I took quite some time until I figured how matplotlib/pylab works, but
eventually I succeeded. Hopefully you'll get to some good results
faster than me :)

I've been using FusionGraphs (flash based graphing, generating the

python using PIL or anything, but it's been quick and effective.

Thanks Joseph.  You might find it interesting to take a look at our
Diagra product datasheet...  we've been in the financial charts
business since 2001
   http://www.reportlab.com/docs/diagra-ds.pdf

The engine and most chart types have been in the open source package
since 2001, but we've not really promoted it.  Now that we're getting
into Django, hopefully we'll get some nice examples out to inspire
people..

I'll second (third? fourth?) the matplotlib vote.  I've used it in a
couple of projects with django and it works quite well.  My biggest
complaint about matplotlib is the couple of dependencies it wants, but
the latest releases have taken care of most of that problem, so give it
a try.

If matplotlib doesn't work for you, there's another lib called
ChartDirector that we've used at work.  It's got PHP, and Python front
ends and the api is fairly consistent.  I think it costs about $75 for a
license, but I don't really remember.  Check it at
http://www.advsofteng.com/cdpython.html

Someone also ported the excellent JPGraph PHP lib to python.  You can
get it at http://metagram.webreply.com/ although I've not looked at it
in a long time and I'm not sure how well maintained it is.

Hope that helps ya,
jeremy

If you don't mind using Flash as the output medium you could try this:

Works with anything that is able to output XML, I've used the PHP
