Data analysis software

I'm really bored. I had to do lats of work, but I spend mainly for programs, that don't work as expected.
I wrote a c code to generate datas, such as creating gaussian distribution, weather this gaussian is gaussian, or distance of two atoms obey gaussian etc..
My data set is spaced and simple such as

-0.074636 2.500000 1.000000
-0.074491 2.500000 0.000000
-0.074345 2.500000 0.000000
-0.074200 2.500000 0.000000
-0.074055 2.500000 0.000000
-0.073909 2.500000 0.000000
-0.073764 2.500000 0.000000
-0.073619 2.500000 0.000000
-0.073473 2.500000 1.000000
-0.073328 2.500000 0.000000
-0.073183 2.500000 0.000000
-0.073037 2.500000 0.000000
-0.072892 2.500000 0.000000
-0.072746 2.500000 0.000000
-0.072601 2.500000 0.000000
-0.072456 2.500000 0.000000

Where first coloum is X values (as you can see it is linear) and third coloum is Y values, changing with X. The problem is i cant use gnuplot because I DON'T WANT TO write code to generate simple datas, x-axis labes, fittin datas normalizing them etc.
I wrote Pardus-kullanicilari list about a plotting tool but of course there was no response. Pardus is still a small baby with small number of babysitters.
I went to kde-apps and downloaded qtiplot. This app is very usefull and easy if you can install (in fact it's not the author's problem) you need to install and complie qwtplot3d, which is library. But it's not self-installed, i need to copy libs and headers required directories. My story has not ended.
After a succesful install the prgram is light and except importing my datas it plots neathly which can be configured easily.
Yes it does not importing datas. What i do is to load data to openoffice and copy&paste. Undo is cleanin whole datas.
Why don't i want this in open office?
Because, icant configure plot and plot is self behaivoir, make whatever it wants to!
