Excellant, solved my problem with not loading above test file format.

replace
p=re.compile('\\[(\w\w\w) (\d+) (\d\d)\d\d)\\] ([\d.]+)');
with
p=re.compile("\\[(\w\w\w) (\d+) (\d\d)\d\d)\\]\\[(\d\d)\d\d)\\] ([\d.]+)");

and
percent = m.group(5)
with
percent = m.group(7)

must be a format difference between my battery-status and others.

This could be a really usefull app. I like plotting graphs, but app writters generally integrate them into something else or use strange static input formats. I can see how battery-graph could be enhanced to covers lots of useful formats, not least CSV.

Excellant app, whish you luck in packaging it up

I modified battery-graph to accept either input format from battery-status. I've updated the download from post #1. Please retrieve it again if you are having problems.

I wish battery graph could show you which apps were drawing the most power based on load and usage, as well as possibly components. Now I don't know how possible that is, but it'd be worth looking into.

I'm a nice guy. I took the debianisations of youamp and modified them heavily to fit this. This will install battery-graph to /usr/bin, the gtk chart stuff to site-packages. I've also written a desktop file so it can be launched from the menu and I've also added dbus integration. I've left hints in various places about any changes I did.

In a scratchbox, doing a "dpkg-buildpackage -rfakeroot" will produce an ready to install debian package. This could be uploaded to extras if you wanted to (after checking everything first . But also remember that battery-status is not in extras).

qwerty12: thanks for your help. Can I run dpkg-buildpackage on the N810? If so, where do I get it from?

Because this is a python package and no compiling is needed (in the compiled languages sense anyway) and this doesn't run an configure of any kind, you probably could get the needed stuff from the SDK repo which is from:
https://bugs.maemo.org/show_bug.cgi?id=3405#c6

I'd guess you need dpkg-dev, python2.5-distutils, python2.5-dev. But installing them on an N810 will take copious amounts of space so I'd really do this in a scratchbox where possible.

I tested the package BTW :P, works well . Oh yes, before I forget, you probably want to add an license to that. In setup.py, I've left it as GPL v3 because that was what youamp was and I don't really know what this is licensed under.

For packaging, have you tried pyPackager ?

Just used it to create a fake package for libxml2juuiiii that pkgtkeditor upgrade required, so guess it works even for a complete newbie to python and maemo packaging like me.

You may find pygtkeditor useful for on platform development as well.

I packaged battery-graph into a deb file, making it easier to download and run.

I also wrote a replacement for battery-status, called battery-info. Its like battery-status, but shows more information. In addition to the battery status, it shows the temperature, the number of bytes of new network traffic and the CPU speed. The network traffic and CPU speed are only shown when you use the -d flag. There is also a -p flag, which analyzes process usage. It shows processes that have accumulated CPU time, and lets you know how many process have come and gone. These two outputs are differential, and are shown starting with the second output with -d.

Instead of dbus signalling, battery-info gets battery status from the lshal command. This should eliminate the problem of activating the battery applet.

I've updated Post #1 with both downloads.

This is also interesting to plot how fast it goes to 100% while on, while on adapter.

You can also use this to test every day, putting one application off (for example OMWeather; not to bad mouth OMWeather, this is just an example, and besides that the settings of each application affect their CPU cycles as well). This way you can (roughly!) debug which applications use more resources than you wish for.

Linking errors.

It requires Linux kernel version >= 2.6.24

So, no (full) WiFi driver. For now.

I forgot to mention that you need to download rps (the real Linux ps command) from http://www.makikiweb.com/n800/downlo....2.7.armel.deb
to use the -p flag.
