It can be done with web2py and gluon/contrib/websocket_messaging.py easily. 
The problem is that how depends on details.

Nice. In the example there is this code:

data.push(random());

In the example the problem is updated using random() points. I think Vera's 
problem is that the data must be pushed from the server to the client. She 
needs a websocket.

I use d3.js - seems to at least awesome.

Here are some examples with real time paths:

[web2py] Re: real time graph

[Massimo Di Pierro]

Hello Vera,

I agree with some of the answers below: you need javascript for real time. 
But there are many subtleties. In particular what is the data source? and 
when does it change? How often does it change?

For example if you want to the graph change be triggered by a rare user 
event you can make an ajax request to update your graph (this could be made 
with matplotlib or JS).

If instead the graph change is triggered by a frequent user event, for 
example the movement of the mouse, you need to use JS.

If the graph changes because of events generated server side (for example 
you are displaying a graph of CPU usage in your server) then you need a way 
for the browser to refresh its content periodically. One way is to make 
ajax requests, grab the new data, redo the plot clientside in JS. Another 
way is to use a websocket.

If you give us more details we can try make a working example.
