Easy is always open to debate. But here is one way to accomplish what you want In[22]:= f = Interpolation[Transpose[ {Evaluate[poissonProcess[4, 20]], Range[0, 20]}], InterpolationOrder -> 0] Out[22]= InterpolatingFunction[] Plot[f[x], {x, 0, 6.7}, AspectRatio->.3]; -- To reply via email subtract one hundred and four
