How to run two scripts simultaneously while sharing data and plotting?

I need to run two functions simultaneously namely func1 and func2. However I need func1 to make a plot based on some data (coming on the serial port and) being read and processed by func2.

It is not possible for me in any way to merge the two functions into one. I looked into parpool but it seems like it doesn't allow making figures while running in parallel.

Please recommend how can I make func1 plot a figure based on data coming from func2 in parallel?

save the data of func1 periodically. and read it from func2 and plot
