20 * GNUPLOT |

|
22 In order to show graphs, you can setup gnuplot this way to say for example the downloaded |
|
23 data in a.txt. If the header reads: |
|
24 # Start: 2010-11-27 23:4:28 |
|
25 # Num Samples: 1118 |
|
26 # Time between samples: 30 s |
|
27 |
|
28 |
|
29 You can use the unix command date to transform that into a timestamp: |
|
30 $ date '+%s' -d '2010-11-27 23:4:28' |
|
31 1290895468 |
|
32 |
|
33 Then in gnuplot you can run, considering the values of 1290895468s since the epoch and |
|
34 samples every 30 seconds: |
|
35 > set xdata time |
|
36 > plot "dutxa.txt" using ($1*30 + 1290895468):2, "dutxa.txt" using ($1*30 + 1290895468):3 |
