How do I create a 2 plot chart with time stamp on x axis?

The attached has the wrong time on the x axis. I am able to get this to work with only 1 plot. In order to get the chart to even except a second waveform I had to bundle the 2 doubles and feed it into it. I then deleted that and created the second waveform and fed that into the chart. I'm sure this has something to do with the chart properties but I can't deduce what to change. I noted the coerce dot on the chart input but I'm not sure what is being coerced. I've tried to adapt several examples I found on these forums but just can't seem to get anything to work correctly. I know this is not a good idea to create arrays in while loops and later I'll be replacing the chart with a graph.

Ok I got it to work. What I did was replace the bundle function of the waveforms with a build array function. This broke my clear history property node but I fixed that by creating a new control. Now I'm going to try it again from scratch to figure out what happened
