Gnuplot program graph

i new to using the gnuplot program.

I am trying to create a graph which will calculate the frequency for the range of values in a given column, and plot it as a histogram

x-axis being range
y-axis being frequency

I have created it using excel...but couldnt not figure it out in gunplot.

Heres an example of how my file looks:

id1 id2 value1 value2
a b 0.01 0.03
a2 c 0.05 0.06
a3 d 0.1 0.13
a4 e 0.12 0.14
a26 z 1.5 1.4

so if i want to plot the values in column4(Value2)

i have to first compile a table showing the range and frequency:

range frequency
0 - 0.1 3
0.1 - 0.2 6
0.2 - 0. 3 5

how would you compile such info from Value2 column using gnuplot?
Once i get it to the above format...i know how to graph it.

I have an enourmous number of such files...and exporting each one to Excel and a very painful and time consuming process.

Please help with your suggestions.

You can't do it from gnu plot. You need to write your own program to do the binning first.
