Full Discussion: Problem creating graph with gnuplot with time on x-axis

I just realised the code I posted was incomplete. Since the x axis is time gnuplot has to be told so.

So the final code looks like this:

Code:
gnuplot
set terminal png
set output "graph_realtime.png"
set yrange [10:50]
set timefmt "%H:%M"
plot "./values_minute" using 1:2 title 'Temperature' with lines, \
"./values_minute" using 1:3 title 'Humidity' with lines

This works without giving an error message, but all the values is located at the extreme ends of the graph.

Added
Code:
set xdata time

which helped. But now I need to make the x axis easily readable, maybe tics every 15 minutes.

Added
Code:
set xtics "14:00", 900, "16:00"

which help but it's still showing the time as hours:minutes:seconds, how to only show it as hours:minutes? And does it exist an easy way to replace (in my example) 14:00 and 16:00 with proper values, i.e. if it was measured from 09:05 to 10:04 the first tic (excluding the edges of the graph) would be at 09:15, the last at at 10:00? I guess it's similar to
Code:
 set xtics "%H:M", 900, "%H:%M"

or do I have to create a script that read the first and last value from the table with values and insert the correct time?

Adjust X & Y screen axis

I'm using my wife's Macbook, and I just noticed that her screen is off axis, but I can't find a way to adjust it. I've tried playing around with resolution in preferences, but nothing. Maybe a terminal command for adjusting the x and y values of the screen? Any and all suggestions welcomed :) (2 Replies)

IRSEND(1)								FSF								 IRSEND(1)

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
