Hi all
Im after a simple graphing program. I use Z grapher in windows and would like to find one for Linux

What I would like is a program where I could type in the x and Y co ordinates and then click on a button to get the regression ,and to find the equation

Also the area under the graph,

I have been looking , but for example Kplot ( all the ones I have looked at) are not . well I couldnt find out how to enter in the data lets put it that way !

I tried grace. but ot wouldnt load for me

Any Ideas??

Kind regards

Stephen

If you dont mind little typing, you can use gnuplot, its a very simple interactive plotting package.

With gnuplot you can export your result in postsript file, tex files, fig files.

You can also integrate them under LateX using epsfig or PSFRAG for example.

Yes, gnuplot is what you are looking for.

This is a site with examples I often use:

Ive downloaded gnuplot , but the command line looks daunting ..any with a GUI ,,,
With Zgrapher for example I click Xy type in the info then click regression /dy/dx and there is the result ... I have use it a lot for what if ... so whange /compare data a lot ..

So the quicker and easier to use ..the better

If all you need is to generate some scatterplots easily and with a GUI, have you tried gnumeric? It can create charts pretty easily, and the statistical tools are second to none in the spreadsheet world. You can also export your figures as svg.

For a fair amount of stuff you can use this cool gnuplot frontend I packaged up called plotdrop. The homepage is: http://icculus.org/~jcspray/plotdrop/ if you want to see a little more about it. It's in the Universe repository.
