[Gnuplot-info] labels and data offset

[howudodat <pe...@ho...>]

I am having two issues with my spectrum plot.  (visible at:
http://imagebin.org/280352)
1.  the plot command is being added to the graph as a label.  How can I
disable that?
2.  the entire plot seems to be shifted.  the xtics seem to be rounded with
the tics being: 133.180 E6, 133.200, 133.220, 133.240, 133.260, 133.280,
133.300 E6
the dataset however is:

    133198120    -104.79    -104.43    -104.12    -104.69    -103.85

    133217194    -106.28    -105.68    -105.73    -106.46    -106.86
    133217957    -106.19    -106.4    -106.07    -106.32    -106.71
    133218719    -106.64    -104.9    -105.93    -105.53    -106.68
    133219482    -106.78    -106.17    -106.75    -106.2    -106.36
    133220245    -106.34    -106.24    -106.3    -105.97    -107.14
    133221008    -106.55    -105.75    -105.86    -106.72    -106.29
    133221771    -105.2    -105.7    -105.39    -106.39    -107.62


and thus the plot "appears" to be shifted in the graph, the first line being
at 133.198
here is the plot command:

    set output filename.'-spectrum.png'
    set title titlename."-spectrum"
    set format x "%.0s e%S"
    set format y "%.0f"
    set ylabel "time (secs)"
    set xlabel "frequency"
    set xrange[*:*] noreverse
    plot filename.'.csv' nonuniform matrix using 2:1:3 with image
