Plot 3 different size blocks inside height velocity profile with dash line spanning to the right (please see image)

@juan sanchez - what is your question? What have you tried so far?

Hi, what I want to do is plot 3 blocks of different heights, independent of the x axis being velocity. I just need to plot 3 blocks and a dashed line moving to the right. I guess I cau use horline and vertline but I would like to see how is done.
