hi,
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 couldn't 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
etc
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 graphing...is a very painful and time consuming process.
Please help with your suggestions.
thanks
