Let's say I have a 10X10 array that is a multiplication table, multiplied times some arbitrary integer constant. For this example, pretend that constant is 5. So the first row would be 5, 10, ..., 45, 50; the second row would be 10, 20, ..., 90, 100; etc. When doing …

A simple physics graph... [code=python]import pylab a_time = range(0,141,10) a_R = [3.0,2.8,2.56,2.36,2.2,2.0,1.86,1.7,1.6,1.43,1.3,1.2,1.1,1.06,0.96] for i in range(0,15): pylab.plot(a_time[i],a_R[i], 'x') pylab.errorbar(a_time[i], a_R[i], 0.5, 0.05) pylab.show() [/code] I'm guessing the [icode]pylab.plot[/icode] line isn't needed, but even with this there is nothing connecting the plots together. I'm pretty sure there wasn't anything extra needed …
