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,

Betreff: [mg28825] Creating graph with only a view [few] data points


Hello,

I'm a student at a school for technicians (electronic). 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
