You are quite correct that you cannot do something like
Plot[NIntegrate[{expr1,expr2,expr},{x,a,
100}]//Evaluate,{a,0,10}] and get multiple styles.
But I doubt for something like this, the issue of a single style
vs multiple styles would arise. If the unless the expressions
are pretty simple, the execution time for this Plot will be
terrible. And if the expressions are fairly simple, then it
should be possible to do
Plot[Integrate[{expr1,expr2,expr},{x,a,
100}]//Evaluate,{a,0,10}] which would allow multiple styles.
Unless you have a very fast machine or a lot of patience, doing
Plot[NIntegrate[... isn't a good way to do things for
non-trivial integrals. Execution time is going to be a far
bigger problem than multiple styles.
