Hello ... I was wondering if anyone knows of any freeware graphing software (all it has to do is make proper graphs with even scales on both axis (not like excel does it)). I've tried something called RJS graph but it makes my computer hang when saving and loading graphs, which is a real pain. I've been searching for about two hours and haven't found anything useful. Maybe I'll write my own program if worse comes to worse, but it would probably just be better to draw them by hand then ... Anyways, if you know of any such software send 'em this way, thanks.

I've used graphmatica a few times, and it's a decent freeware program that lets you save your graphs as images =)

If you mean vectorial drawing, the you could take a look to Inkscape;
If you need a bitmap editing app then try Gimp
For functions then analysis 2.3

Of course, you can try OpenOffice to see if it is a little more flexible than Excel.

Can't really suggest an alternative, but it isn't terribly difficult to force excel to create a graph with even scales if that is the only thing keeping you from using it.

Wow I'm an idiot, I was trying to use a line graph for a line graph when I should have been using an XY Scatter Plot for a line graph. Silly me ... That inkscape program looks like something I was looking for a while ago, so I'll check that out.

Thanks for the replies.

Well, this thread wasn't what I was hoping it would be, so let's see if I can't make things more interesting...

Is there any real charting software? Excel is great for a lot of things, but often times it just does not cut it. Not enough power and flexibility for things like controlling axes, getting things just so, etc. I'm thinking preferably freeware, or at least shareware so I can evaluate before buying.

Juding as it's a missing feature of PSPP, I think SPSS may have the feature you're looking for.

DreamCalc may have what you are looking for. It spits out pretty looking graphs...

pffft, just head straight for the daddy of graphing programs - GNUplot.

...and then chew your own lips off in frustration at the command-line interface and startlingly poor "help" system.

It'll do whatever you want, but it will not make it easy for you.

Yeah some regression equations would be nice in Excel / OpenOffice. If only there was a freeware equivilent of SigmaPlot.

You can perform regression in Excel. There's a function LINEST (or something like that) which does calculates linear regression giving you a and b values (from the equation y = ax + b) and if you right click on a chart and click add trend-line there's a range of things to choose from.
