I must state that this is my first time dealing with gnuplot. I am getting cpu temp via ipmitool and sending it to a file. The data is appended to the file in this format $TIME $CPU1 $CPU2, the time var is TIME=$(date +”%Y-%m-%d %H:%M”) in the script that generates the data.

Here is the script im using to plot the data:

#!/usr/bin/gnuplot

# Set the output file type and name
set terminal png size 800,600
set output 'cpu_temps_plot.png'

# Set the title and labels
set title "CPU Temperatures Over Time"
set xlabel "Time"
set ylabel "Temperature (°C)"

# Set the x-axis to use time format
#original code
set xdata time
set timefmt "%Y-%m-%d %H:%M"
set format x "%H:%Mn%m/%d"

# Plot the data
plot "cpu_temps.dat" using 1:2 with lines title "CPU1 Temp", 
     "cpu_temps.dat" using 1:3 with lines title "CPU2 Temp"

When executing the plot script, I get the following error. I have run to the end of my rope

#gnuplot plot_temp.gp
