I have tried a lot and also searched this forum but I think I need some help ...

Im trying to adjust the Matplot Graphs (different scale, lables etc .. ) by changing the corresponding
python files in /graphs/ ... but my changes are not showing, still the same/old graph is being created.

I tried deleting the pgn file in /static/ to make sure a new pic is being created every 15min, I also deleted
the corresponding pyc file, using a different browser (clearing cache) ... nothing has helped so far.

I have to say that sometimes "out of the blue" I can see my changes, sometimes the next day or at least many hours after I did the python changes, but I would expect the changes in the py files being in effect "right now".

Is it maybe a a problem with the apache?

Thanks

Axel,

Without more information, it is hard to be sure, but I think you are not killing the main GroveWeatherPi python program when you change the MatPlotLib graph files.

Restart the program and the changes should show up.

We have see similar flakey behavior in our Project Curacao project. We finally just kill the program and restart it and all the files are good.

What are the appropiate restart/kill commands. Thanks .axel

Axel,

Yes, restarting the Pi should be making graphs each time. But remember Graphs are only created every 15 minutes (I think - look at the add_job code in the main program).

Restart and kill commands depend on how you are starting GroveWeatherPi.py

ctrl-c or ctrl- (break key - | ) will kill the program if you are in the same terminal window.

ps xaf | grep python

and then:

sudo kill -9 (process number from ps command above)

will also do it.

BP

Best,

BP
