hi, i want to plot a set of 3-D data. i have 3 spatial co-ordinates (x, y, z) and then a physical quantity i have measured. Is there a straight forward free plotting package i could use to plot this data? thanks!

i need to calculate radius of curvature of 1 MeV KE electron in 1 Tesla magnetic field. r = mv / eB what is the (relativistic) speed, v, of the electron? (ans: 0.941 c ??) then i think you use p(rho) = mo. V / sqrt (1 - v^2 /c^2) = mv (ans: 7.59E-22 kg m/s) e = 1.6E-19 C B = 1...
