xy chart time
You need to display the x axis in a time format. Do you have a problem formatting the axis or do you have problems creating the correct data structure for the graph?
Also, if your timing is constant, all you need is a plain chart. Write x0 when the program starts (i.e. outside the loop, via a property node).

That's a very important distinction. if the dt varies over time, you need an xy graph and much more complicated data structures. If dt is constant for a given run, all you need is a chart.
Here's using an xy graph, allowing for variable time increments.
This is just a quick draft. Note that the data structures grow without limit, so you need to implement measures to prevent eventually running out of memory or slowing down due to memory allocation overheads.
(note that also the "build xy graph" express VI could be used, but I don't like express VIs)
