Sent from the Gnuplot - User mailing list archive at Nabble.com.

define the gauss-function,

gauss(x)=amplitude/(sigma*sqrt(2.*pi))*exp(-(x-position)**2/(2.*sigma**2))

fit it to the data, 

fit 'datafilename' gauss(x) via amplitude, position, sigma

and then plot it:

plot 'datafilename' with histeps, gauss(x)

and try to set 'amplitude', 'position', and 'sigma' to reasonable
values before fitting, otherwise the fit may get lost.

1. what do you mean by 'ladder graph'? there are several different
graphs when searching for 'ladder graph' with google (images).

2. do you work with a data file? if yes, how does it look like?

Hi
1. ladder grapg like this attached graph.
2. I don't work with data file.
Thanks

Hi
1).For example, ladder grapg like this.      How to plot like this with gnuplot?
 
Y-axis(average session/s)
13
12                          
11                              ********
10                              *
9                                *
8                    ********
7                    *
6                    *
5          *******    
4          *
3          *
2*******  
1         
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15  :X-axis(min)
 
 
Every 4 minutes y-value suddenly change from 2 to 5, 5 to 8 and 8 to 11 respectively.
 
 
2). I don't work with data file.

 
thanks.
           
Cooky

plot 'with steps'

an example:

set xrange [0:pi]
set samples 10
plot sin(x) with steps

Hi
1. ladder graph like this attached.
2. No, I don't work with data file.

plot "< join file1.dat file2.dat" using 1:($2+$3) with linespoints

if 'file1.dat' has more than 2 entries per line you need to increase
the '$3' in the 'using' option.

the 'join' command is in the 'gnu coreutils' which are normally
installed on every linux-system, for windows you need to
install it (search for 'GnuWin').

Thanks Thomas,

I wasn't aware of the possibility of running commands and using their
output as "files". Very nice!

Thanks again for your help,

nick

if the y-values can be described using a function (like in your example):

set samples 4
f(x)=1./x
set xrange [1:4]
plot f(x) with linespoints

Thanks, really wonderful!

I did something like this, (of course very awkward one)

p [0.85:6.5] [0:1.2] 1/x,'-' w p
1 1
2 0.5
3 0.333
4 0.25
5 0.2
6 0.166
e

just to share with others ..

Sincerely,
Jon

a little bit simpler:

p [0.85:6.5] [0:1.2] 1/x,'-' using 1:(1./$1) with points
1
2
3
4
5
6
e

or a little bit more difficult:

set xrange [1:4]
set samples 4
set table 'temp.dat'
plot 1./x
unset table
set xrange [0.85:6.5] 
set yrange [0:1.2]
set samples 100
plot 1./x, 'temp.dat' with points

you could cut the first word (the line number) using awk:

history 10 '| head -5 | awk "{for(i=2; i<NF; i++) {printf(\"%s \", \$i)} ;
print \$NF}" > diary.gp'

Hi Thomas,

thanks a lot! I had never heard of that special file before, many thanks
for pointing it out to me.
