About this for a start....

c[t_] := \[Piecewise] {
   {0, t >= 0 && t < 10},
   {1, t >= 10 && t < 20},
   {0, t >= 20 && t < 30},
   {-0.5, t >= 30 && t < 40},
   {0, t >= 40 && t < 50},
   {2, t >= 50 && t < 60}
  }

Plot[c[t],{t,0,60},Filling->Axes,FillingStyle->Orange]

I would like to plot something like this with version 6
At time 0 to 10 the current is 0, at time 10 to 20 it is 1, time 20 to 30 it

is 0, time 30 to 40 it is -0.5, time 40 to 50 it is 0, then at time 50 to 60

it is +2.
I would like to break each of these up into something like this eq1:= for 0 
to 10, eq2 := 10 to 20 and so on.  Then I want to combine the equations into

a plot.  Then I would like to fill in the different sections with different 
colors.
I will then go one with another eq. that uses these results and filled in 
areas to show  how they interact.  I will worry about this after my first 
question.
Can some one help me?
thanks
