Package: psensor
Version: 0.6.2.17-2+b1
Severity: normal

Dear Maintainer,

psensor doesn't show any graphs (curves) of CPU temperatures.
The range of the vertical axis is from "0C" to "0C".
psensor does show temperature values such as "43C"
on the right-hand side of its window.

lm-sensors is installed and the command /usr/bin/sensors
works (i.e., shows CPU temperatures).

Regards,
Ryo

What are your settings about 'Monitoring duration' and 'Measure update
interval' (in the preferences window)?
Did you wait more than the measures update interval? The Graph cannot be
drawn before few measures have been retrieved.

Could you please send me the complete output of the sensors command?

Could you please delete the $HOME/.psensor/log file then launch psensor
with the following command: psensor -d 3, wait a couple of minutes and
send me the file.

Thanks,
JeanFI.

Just in case...have you enabled the curve of at least one sensor? I mean
the checkbox in the column 'Enabled' of the table?

Could you please send me a screenshot of the main application?

What is you desktop environment? Gnome-Shell?

BTW, thanks for the information that you have sent, I will analyze them
soon and try to understand what goes wrong.

Hi JeanFI,

Thanks for your prompt response.

Update interval is 1 second;
Monitor duration is 10 minutes;
Measure update interval is 1 second.

I believe these are default values, as I haven't changed anything.

Just in case, I left my office for lunch and came back. Still, there
is no graph!

OMG! You've just made me realize the existence of
the "Enabled" column! I installed psensor just two hours ago
and didn't see the curves and sent the report.

I've checked the "Enabled" boxes of my four CPU cores
and four corresponding curves are now shown.

Sorry that was sloppy of me! but may I suggest that those
curves should be enabled by default?

Cheers,
Ryo

I'm wondering if it makes sense to change things
in the following way?

1) If no graphs are enabled, don't show the graph
panel on the left.

2) Change the word "Enabled" to "Graph" or "Show Graph" or
something like that.

As to (2), since the sensor values are displayed,
it's not necessarily clear what "Enabled" means.

In that sense, the following alternative may be good:

1+2) When and only when "Enabled" is checked, are
BOTH temperature values AND the graph displayed.

Just my two cents.

No problem, at least you raise an usability issue which needs to be
addressed.

On some computers like for example the Lenovo W500, there are around 20
sensors. If all curves are enabled the result is quite bad and not a
good first impression for the user. That's probably better to enable by
default only CPUs and GPUs which are the more important. I will try to
think about this kind of solution for a future release.

Regards,
JeanFI.

The layout of an application should not
change except if the user is doing an action which clearly
implies such change without any deep understanding of the application
specificities (resize the window, hide a inner panel, etc).

If it displays a label like "No sensors graph enabled" in the middle
of the graph canvas it might be more obious.

I agree, it is confusing. "Graph" sounds good.

There is a need to hide sensors from the table, that's something that
I would like to implement at some point, but I don't
see any reason to hide a temperature if the sensor
is displayed in the table.
