Hello Oliver, draw your curve on squared paper and identify the coordinates {x, y} of your "significant points". Then proceed as shown below: IN: lst = {{1, 1}, {2, 1.5}, {2.5, 2}, {3, 3}, {4, 5}, {5, 6.5}}; itp = Interpolation[lst, InterpolationOrder -> 3]; Table[itp[x], {x, 1, 5, 0.5}] Plot[itp[x], {x, 1, 5}] Best regards, Matthias Bode Sal.

I'm making my calculations with Mathematica. For a documentation I want to create a graph with the characteristic of a diode and a transistor. I'm looking for a software, with which I only have to enter some significant points of the graph, the scale, and the legend. Then the software should create the graph. Does anybody know a software which could do that, or is it possible to do this with Mathematica. Greetings Oliver
