I need better graphing software

electricitylikesme

Without needing to write my own, or learn MatLab in rather extensive detail in order to accomplish the former.

What I want, is something which will let me throw in my variables and then do some simple analysis on them visually. Say for example I graph something and I want to find peaks, or I'd like to integrate between two points under the graph, I'd like to be able to choose those points visually.

Is there anything like this, either as a toolbox or a plugin or a stand alone program?

You can definatly display max and min points on a graph in excel simply by right clicking somewhere on the graph and messing around with it. I'm fairly sure you can do some area under the graph plots, but to be honest I'm not exactly sure where to find those.

Matlab would be your best bet, there is however another program (that also costs money) which currently escapes my memory.

Matlab is what you want. The simple graphing tools aren't difficult to learn and it'll do differentiation for you, making it trivial to find maxes and mins. It'll do integration, not visually though, although you can find points on a plotted graph and plug them into the command line.

EDIT: Also check out Mathematica or Maple I haven't used them much but they're the other big engineering/math software packages.
