#48 Graphics not showing: Message: no valid data points

[Sathors]

Hi,

I am using the arc gtk theme on archlinux, with klavaro 3.02.
It is a dark theme. I use the same theme with qt, telling qt to use the gtk theme.

When looking at my progress, the window is empty, and the Y and X fields are empty as well. Well they seem to have values (when given the focus, the cursor is in the middle), but nothing shows, and I can't select the text.

Thanks for the great software though!

It seems it has nothing to do with the theme.
Actually when run from the terminal, when looking at the stats, I have the following in the terminal:
** Message **: no valid data to plot.

I tried to change the GTK3 theme using the GTK_THEME variable to confirm it had nothing to do with my current theme.

I have tried deleting my ~/.local/share/klavaro directory, along with my ~/.config/klavaro directory.
When doing a fluidness exercise, the stat_fluid.txt file does not get created.

So the problem is the creation of logs for fluidness. I guess you could be using text with language different from the default one, and that is not acceptable by the program for logging purposes. Could you launch it from the terminal and show the messages there when finishing the practicing?

[Sathors]

Hi Felipe. I did a practice, then clicked on "Progress".

+✘1 ~$ klavaro

Does the problem happen only with fluidity? Have you tested also with velocity, for example? And can you verify that you have normal write access to the folder /home/sathors/.local/share/klavaro/ ?

[Sathors]

For the velocity, I had not used it so far, but the same seems to be happening:

** Message: no data yet, no statistic file:         
/home/sathors/.local/share/klavaro/stat_velo.txt    
** Message: no data yet, no statistic file:

 espeak -ven -k1 --punct 'Delivered'                
** Message: no valid data to plot.                  

The permissions are alright (my user is sathors):

So it seems that the data points do exist and get written. It is the reading that must have a problem. The structure of the file seems to be ok, with tabs between each column.

[Felipe Castro]

It seems a problem related to the locale. As you use en_UK, the program is not recognizing it as a separate locale, mixing with the generic C English.

For now, if you want to see your plots, switch to C language (US), and change the "English UK" tag in the fluid file to only "English" (just a work around). You can load the specific en_UK.paragraphs to practice or any other text from the "Other" button.

I'll see how to fix that in next release, ok?

[Felipe Castro]

Fix commited to SVN.

[Sathors]

Yep, you were right, the workaround works. Thanks for the fix!
