Plotting power consumption diagram issue

[sabriCHALLOUF]

Hi,
I detected an issue when plotting the power consumption graph using plot_oml_consum.

Test Case :
+ BOARD : M3
+ Binary : binary of the example timer_periodic_wake_up (from the RIOT OS sources)
+ Number of nodes : 4
+ IoTLab Site : Grenoble
+ Used nodes : 95, 96, 101 and 102
+ Experiments numbers : 234396, 234385 and 234384

Expected Results :
+ OML files contains power consumption values 👍
+ OML plotter should use the OML file values to plot power consumption graph.

Real Results :
+ OML plotter ( plot_oml_consum -p -i ~/.iot-lab/last/consumption/m3_95.oml) detect some errors when lunched 👎

Here is the errors message :

challouf@grenoble:~$ plot_oml_consum -p -i ~/.iot-lab/last/consumption/m3_95.oml
/usr/local/lib/python2.7/dist-packages/oml_plot_tools/common.py:147: ConversionWarning: Some errors were detected !

I like to add that I used also the -X option when logging with SSH but still the same problem.
Thank you in advance

Hi, I have just tested with your homedir. I put my SSH public key on your account profile and test to plot the file with success. I save the plot in your homedir with the name Figure_1.png

fsaintma@orval:~$ ssh -X challouf@grenoble.iot-lab.info
challouf@grenoble:~$ plot_oml_consum -p -i ~/.iot-lab/last/consumption/m3_95.oml
^Z
[1]+  Stopped                 plot_oml_consum -p -i ~/.iot-lab/last/consumption/m3_95.oml
challouf@grenoble:~$ ls
...  Figure_1.png  ...

So I suppose that you have a problem with your SSH client configuration and export display.

Best regards.

Hi,
Thank you for the response.
I updated my ssh keys and still the same problem.
I don't know what to do to resolve the problem.

Best Regards

I Like to add that the problem appears in the Windows environment but not in Linux one. I tried with Ubuntu 16 and 20 and it works well.
