How to plot from the discrete data?

Show all headers | View raw

Dear gnuplot society,

I was writing my article and came to a desire to see my data
graphically to have better picture of the process.

Very bad that I can't post an attachment - I painted up my data and
could show you to ease your understanding.

I will try to write it here using gnuplot terms with some comments:

  gnuplot> set title "Life as it is" \\
  gnuplot> set xlabel "Jobs, thousands" \\
  gnuplot> set ylabel "Time, seconds" \\
  gnuplot> set xrange [1:200] \\
  gnuplot> set xtics 25 \\
  gnuplot> set xtics add(1, 10, 25, 50, 100, 150, 175, 200) \\
  gnuplot> set yrange [0:60] \\
  gnuplot> set ytics 5 \\
  gnuplot> set ytics add(0.6, 2, 4.8, 12, 29.8, 41.4, 52.4, 55) \\
  gnuplot> plot ..

Let me know comment please: I have a graph with two discrete functions
(or data sets) of the same domain (axe x):

X axe is called "Jobs, thousands", it ranges between 0 and 250. It has
the following points: {0, 1, 10, 25, 50, 100, 150, 175, 200}

The range of values of both functions (data sets) is from 0 to 60
(measured in seconds).

Now the two mentioned functions has such values:
f1(0) = 0 = f2(0)
f1(1) = 0.6 = f2(1)
f1(10) = 2;         f2(10) = 3.2
f1(25) = 4.8;      f2(25) = 9
f1(50) = 12;       f2(50) = 16.6
f1(100) = 29.8;   f2(100) = 34.6
f1(150) = 41.4;   f2(150) = 51.2
f1(175) = 52.4;   f2(175) = 59.2
f1(200) = 55;      f2(200) = no value

I wan to draw all these points using two colours for appropriate
function.
And then I want to connect points to see lines which establish the
graphical imagination - the picture.

Could you please tell me how to do this?

Yours,
Sophie
