You need free and private?  The price is low -- if this is a business why

it's not business it's like a school project, so no money :D


There is another charting library called pygal which is great.  It can
produce output to .svg file format or .png.  You could distribute the files
which will display in a browser.  Or you could build them into web pages if
you are so inclined to build a website.  It seems that isn't what you want

So, the python plotting packages mentioned can create files that hold your
graphs.  As to whether you want to display them on the web or send them
around as attachments to your coworkers, or build some local application to
display them is your choice


Sorry for my confusion :D
I'm still not sure wht to do.
Anyway I would like to plot graph with my data first of all, then I 
could think to share them in network and then online.

Confusing mustang.  You said:

anyway I'm not interested in building website I've only to plot/show data
collecting them from a sensor and plot them in a realtime graph (for
example temperature).

and then you said:

Perhaps you could use a Javascript plotting library (like the one at 
flotcharts.org), and use Python only as a CGI agent to serve plotting 
data when requested by Javascript, at regular intervals?

Having previously written websites using php, and now a confirmed python
developer, you should know this:

Php, vbscript, perl, and perhaps other languages allow the interspersal of
code and html in the same file.  You can't do that with python.  So, if you
begin to wade into making websites with python you may be a little lost
until you grasp the concept of separating code from templates (the html
portion) and how you populate your templates with your code values.  Django
is a popular choice, but some like smaller frameworks like flask, and
others.

You even could use python for the webserver. Read the docs for the module

now I'm using apache. Is it possible to do the same with python+apache

mod_python exists for apache. If your only goal is just a simple website for
your temperature sensor you could do it completely with python. If the
webserver should serve other pages as well I'd prefer apache with mod_python.

my goal is only to collect data and show them or plotting in a graph.

I'm not sure to understand how you are using php, but indeed you can

show instant data on webpage

2016-01-26 Thread mustang 

I've built a sensor to measure some values.
I would like to show it on a web page with python.


This is an extract of the code:

file  = open("myData.dat", "w")

while True:
temp = sensor.readTempC()
riga = "%f\n" % temp
file.write(riga)
time.sleep(1.0)

file.close()

Until this all ok.
Then in PHP I read the file and show it on internet. It works ok but...
First problem. I've to stop the streaming with CTRl-C to load the PHP 
file because if I try to read during measurement I cannot show anything 
(I think because the file is in using).

How can I show time by time in a webpage the output?

Is this an option?

open("myData.dat", "w").close()

while True:
temp = sensor.readTempC()
riga = "%f\n" % temp
with open("myData.dat", "a") as f:
f.write(riga)
time.sleep(1)
