Plotting and Fitting
Hi, I have to learn to plot and fit functions (with error bars in x and y direction).
My question is: 1) Can I do it with sage? Would you prefer gnuplot?
How can I read and plot data like this: http://rn0.ru/show/1430/ easily in sage? 2) And if yes how?
I already tried to plot some randomly created data: http://rn0.ru/show/1429/ And that works great.
3) How can I fit a function (nonlinear) with considering the errorbars?
