One dimensional line chart (sink)

I want to be able to see a line chart of my outputs in real time. 

I want the graph to 'forget' old points after a time (which I set) and I want it to add new points in.

I want the graph to resize with the block. The graph only needs to display one dimension. I want to have many graphs in one model.

I want to be able to get at the raw data, it must look like a CSV (comma delimted)
