Can anybody tell how can I put the two cumulative distribution curve in a same plot?

While executing this command:

plot(x,pweibull(x,shape=1.120662,scale=18.496778),type="l",col=4)
plot(ecdf(SIZEDIST$AVG.µm.),add=TRUE)

the Weibull cdf curve is appeared in some unexpected form. It is not what I was expecting.
I need the first curve as smooth line and the second ecdf curve as step.

Use function lines 

plot(ecdf(rnorm(20)),col='red')
lines(ecdf(rnorm(10)),col='blue')
