[paida-users] PAIDA with Google App Engine?

[Jim B. <jb...@cr...>]

Hello,

I'm a Python neophyte, so my apologies in advance if this question isn't a
good fit for this list.

I'm tinkering with an application using the Google App Engine, and I have a
need for some basic exploratory data analysis graphs such as scatter plots,
boxplots and histograms.  I ran across the PAIDA project and have downloaded
the code; it seems to have everything I need from a functionality
perspective, now I'm trying to figure out if I can make it work with the
Google App Engine.  I need to get the graphical output to a web browser
client.  As I peruse the source code, it looks like the IPlotter function is
where I would need to make modifications in order to construct a graphic
image which could be returned to the browser rather than to the standard
console window display.

Can anyone give me any guidance on how this might be possible?

Thanks in advance,

Jim

Hello, Jim.

I'm the developer of the PAIDA.

There is no description about web browser GUI engine in the online  
documents, but the PAIDA includes a test engine for it.

Download sampleHistogram1D.py from PAIDA website and type
 >> python sampleHistogram1D.py --gui=firefox
and then access to
http://localhost:8080/

This engine is not production level, so you will have to modify the  
source code.

The SVN is used for rendering in the web browser and supported by at  
least Firefox and Safari.

Sincerely,
Koji

Hi Jim,

I'm sorry but I don't have the access to the App Engine. So, would you  
tell me a little more details? Did you have any trouble with running  
the sample code "sampleHistogram1D.py" ? PAIDA in firefox mode doesn't  
use local file system, I think.
