vertical bar determined by frame height

Hi guys,

I'm trying to make a kind of infographics, where I want to indicate certain time period by a vertical bar.

There would be fantastic if this can be done based on frame height, where the bar height is = frame height and the text in the frame is vertically centered.

I have to use more than one bar color (=different styles)

Wonder if anybody has an idea of how can it be handled in a relative smart way.

thanks
