Re: [web2py] Re: matplotlib output

[Richard Dijkstra]

Only adding the .png extention is not sufficient.

outputfile = os.path.join(request.folder,'static','mp1.png')
plt.savefig(outputfile,format='png')


 Outfile from Matplotlib




Besides this issue; is using a temporarily file a mature solution or is 
streaming preferrable?

plt.savefig('c:\web2py\outputfile.png',format='png')

does me give an accessable png-file

To be sure about the comment I made the following view, which had the

The view is not executed. Adding return dict() doesn't have effect. Even 
this dict() does not lead to an error.


{{extend 'layout.html'}}

return dict()

Re: [web2py] what other tools do you use with web2py

I want to make cockpit like application with tabs and embedded graphs. Must be

That example and the info hierarchy and tabs example are the widgets we will be 
using. Looks fine to us.
however I do not have a clear view on how pyjama is used within web2py. I have 
looked at the pyjamas example http://www.web2py.com/appliances/default/show/45

Thank for the conceptual advise.
Besides the examples is also a tutorial for pyjama -  web2py  available.

Would be convenient. I do not know whow wrote the pyjama example on web2py,

Re: [web2py] what other tools do you use with web2py

[Richard Dijkstra]

Anthony,

Do you (and Massimo, I belief you are working closely together) have experience 
with Pyjama and web2py? I have only found a posting in 2009 when it all 
started.

Thanx, for the tip; we will update you on our progress.

[web2py] Rpy2

[Richard Dijkstra]

Hello all,

Ofcourse a lot of math and statistics can be done by Python. Adding R to 
Python as a module through Rpy2 may make this complete. Is there any 
experience using Rpy2 within Web2py?


Regards,
Richard

Re: [web2py] embedded graphics

[Richard Dijkstra]

Richard,

Thanks. I have to figure out what this exact means because I am new to  
Web2py.
Important is the graphics device you use, which one is that Agg, Cairo 
or something else?

Hello Richard,

I think if I had to do what you want to do (I will have to do 
something similar soon) that I would use compute type field to 
generate my graph with lambda function base on orther field input data 
for processing and output from my lambda a graph under PNG image type 
and store the result in db or server directory upload.


I am more inclined into use Matplotlib since it is better fit since it 
is python lib (but nerver use Matplotlib)...


Also, if my processing become to complex for a lambda function, I will 
use internal function :


__functionName(input1, input2, etc.)

Function beginning by "__" are not expose to final user so they don't 
need decorator...


Hope this help.

Hello,

I want to create a scientific website with embedded graphics on Mac
OS.
Plots are created through Rpy2 and Matplotlib.

All the modules run corretly on my Mac but what graphics type will
give me the embedded plots and where should I place relevant code
within the Web2py framework?

Thank you for your reply.

Richard

Re: [web2py] Re: Dynamically created png in HTML

[Richard Dijkstra]

Anthony, Richard,

Thank you for the feedback.

Getting the png file from the static area could be done, and how do I 
get the dynamically create file in that static area?

What would the output path be in :

grdevices.png(file="/tmp/rweb2output.png" , width=512, height=512)

Since src is a relative url, it will end up being 
http://127.0.0.1:8000/tmp/rweb2output.png (assuming you're running on 
your local machine on the default port). Instead, put the file inside 
your application's 'static' folder (you can create a 'tmp' subfolder 
in there), and use src="{{=URL('static','tmp/rweb2output.png')}}". 
Also, use an  tag instead of .
