plotMX

[ninuzzu66]

Hi all

I wrote a simple script for linux to plot meteo.log data file created as follows

cat /<cumulus path>/CumulusMX/realtime.txt >> /<meteo.log path>/meteo.log #In my system, it runs every 5 minutes

To use the script, you just need to set the FILE environment variable to specify where meteo.log is and install gnuplot package.
To learn how it works, just run the script without parameters.

Hope it helps

Bye, Nino

Tried it and got the following result and an output.png file which cannot be read by any image reader on my machine. I had about 5 lines in meteo.log (filling up now of course).

I think you are using an old version of awk.
Is it possible?
Mine is GNU Awk 4.1.4.

[HansR]

I run a RPi with Raspbian and awk is standard supplied by mawk 1.3.3-17
The alternative I may choose is gawk 1:4.2.1+dfsg-1

I must say, it would be nice if different awk dialects would be masked.

I've made some updates.
Now it should work with your awk version as well.

Let me know.

Unfortunately, same result. In the mean time I had installed gawk 4.2.1, result is the same. I send you the meteo.log as well so you can try, maybe it is the log file or I make a fault in the call.

I understood the problem.
In my meteo.log the data format is 03/05/20, in yours it is 03-05-20.
So you have to:
1) change the line set timefmt \"%d/%m/%y_%H:%M:%S\"; in set timefmt \"%d-%m-%y_%H:%M:%S\";
2) use the script providing the data in your own format. Example: ./plotMX.sh 03-05-20 temp

I tried with your meteo.log and it works.

OK, success Nice
But too specific for me and only for Unix/Linux.

I wrote a new post with a plotMX web version.
