Thread: place-time chart

Dear All,

i would like to plot a place-time chart.
There were a survey which registrated forklift moving between buildings. I have the exact times when forklift arrived at building and leaved that. I would like to plot how long the forklift were at each building with a horizontal line. When it moves to another building I would like to plot too and another thing is important that a forklift is empty or pleated.

Thank you in anticipation

Ps. you can find an attachment with a quite weak solution.
