Script works fine. I would like to provide more spacing between the tick labels (1,2,3) and the sub-title (Direct titration and Back-titration) as well as spacing between the sub-titles and axis title. How can it be done?
set xlabel offset 0, -1 will shift both the subtitles and the axis title downward by one character height.
set xlabel "\nTEXT" will create a two-line axis label and place TEXT on the second line.
Modifying your xlabel command to be
set xlabel "\nSample No. " font ",16" offset 0,-1
will make both those changes.
I have a problem. Im trying to do a polar plot, the fact it's that i want to plot some theorical line as some experimental data in the plot. But the theorical line has a range different of the experimental data because i had to do it like that to had gnuplot paint it.
I have the following script:

unset ytics
set xtics ("5" 6, "15" 16.5, "30" 32)
# set the xtics only go from 0 to 6000 with increment of1000 but do not display anything. This has to be done otherwise the grid will not be displayed correctly.
set rtics (5,15,30)
set rtics format ' ' scale 0

And here there are some examples of columns in the direccionalidaddatos.txt archive, the column in the middle it's just the angle in radians but it's usless cause i just want the angle in degrees so just ignore it ;):

And the result it is the image Polar plot
As you see in the image there are two branches that have no points, i want those branches to simply don't disappear cause they don't mean notihng in the graphic.So if anyone knows a form to made dissapear the branches, or to improve the script let me know hehe.
Thanks so much.
Can you just reduce the sampled range for the second plot component?

I do not want to change my data files that come with the first column containing the time values. Then I formatted it on gnuplot to show only the hour and minute. But it is a bit ugly to start the time from 8:00. I would like to start it from 0 and keep the values at the same pace of the data file. I was trying to use a constant like this example shows How do I make a plot in gnuplot with the lowest value automatically subtracted from the y data? but it is not working.
Here are my source and the plot.

The following example uses the newer gnuplot date time syntax (see help timecolumn), e.g. timecolumn(1,myTimeFmt) and set format x "%H:%M" time.
In order to normalize your time series to the first data point you have to store this time into a variable, e.g. t0 which you can "re-use" in successive plot commands from the same datafile.
Note the different time format for the x axis: "%H:%M" for day time and "%tH:%tM" for hours exceeding 24 hours or minutes exceeding 60 minutes, see help time_specifiers.
Edit:
for better readability of the plot command, I "outsourced" the normalization into a function Normalize(). But note that t=0 is still required at the beginning of the plot command.
in case you have some (uncommented) header lines, you need to skip them via skip <number of header lines>.
Code:
### normalize time data relative to start time
reset session
myTimeFmt = "%Y-%m-%d %H:%M:%S"
# create some test data
set table $Data
plot '+' u (strftime(myTimeFmt,time(0) + $1*3600*2)):(cos($1)) w table
unset table
# function to normalize time column to first value
Normalize(c) = (t==0?(t0=timecolumn(c,myTimeFmt),t=1):NaN, timecolumn(c,myTimeFmt)-t0)
# in case there are uncommented header lines skip them
SkipHeaderLines = 0
set multiplot layout 2,1
set format x "%Y\n%m-%d\n%H:%M" time
plot $Data u (timecolumn(1,myTimeFmt)):3 skip SkipHeaderLines w l ti "absolute time"
set format x "%tH:%tM" time
plot t=0 $Data u (Normalize(1)):3 skip SkipHeaderLines w l ti "relative time"
unset multiplot

But the error occurs when you try to start it:

The dollar signs are interpreted as starting a shell variable. Use column instead:

I want to set the background of data labels to white! The considered plot is a data plot of the following data (gnuDC.dat):

8 770.63 771
12 530.33 530
16 385.13 385
24 261.87 262
48 137.71 138
96 81.42 81
The plot command reads:
plot "gnuDC.dat" using 1:2 title "DC: GNU Fortran 4.7.2 + Open MPI 1.6.3" w p ls 1, \
"gnuDC.dat" using 1:2:3 with labels center offset 2.,0.7 font "Helvetica,14" tc ls 4 notitle, \
"gnuDC.dat" using 1:3 notitle smooth csplines ls 14
Which gives me:
It looks ok but think one could read the lables better when the would have an white background. Is there an easy way to add the white background for all labels at once?

With gnuplot version 5 there is a boxed option which does exactly this: give labels a background and, if you want, also a border. The style is controlled with set style textbox, e.g.
set style textbox opaque noborder
plot ... with labels boxed ...

No, for versions 4.6 and earlier there isn't an easy way to achieve this.
