battery-stats-graph-flow fails to do anything

[anarcat]

i get the following when running the flow program on my logfile:

[1239]anarcat@angela:battery-stats$ /usr/share/battery-stats/battery-stats-graph-flow
Argument "" isn't numeric in subtraction (-) at - line 17, <$fh> line 4.
Argument "" isn't numeric in subtraction (-) at - line 17, <$fh> line 4.

Argument "" isn't numeric in subtraction (-) at - line 17, <$fh> line 8.
Warning: empty y range [0:0], adjusting to [-1:1]

now, maybe it's because i have a screwed up CSV logfile, because I have used the procedure in #3 to convert my previous CSV files... you can reproduce the issue with the following .csv file:

timestamp,when,manufacturer,,technology,serial_number,status,cycle_count,energy_now,energy_full,energy_full_design,charge_now,charge_full,charge_full_design

not quite sure what is going on here...

Hm, look like your battery is different from mine, as mine only have the energy* fields filled in. Perhaps the script need to be changed to cope with this?

[anarcat]

yeah, i guess? not sure - the python grapher has hooks for that, that you added, i think. :)
