I tend to rush into sending a reply before fully reading relies. I see now that you were in your 40's when you started to program back in the 1980's. Maybe you owned an Apple or TRS-80 computer back then.
Approx what age were you when you decided to learn C#? Did you have a knowledge of C or C++ first?
Learning new things is also good for the brain and helps prevent Alzheimer's disease.
My first computer was a main-frame at UC Berkeley on which I ran some SPSS factor analysis programs. My first "personal" computer was a little octal training device, followed by a Radio Shack Color Computer
My little career (ultimately at Adobe) unfolded around programming in PostScript, which, of course, is inside printers.
Later, on both Mac and PC, I had experience developing a massive Excel/VBA program to simulate multi-lender power-plant financing and construction.
The moment C# with WinForms came out, I knew this was the right stuff, for me.
The earlier books on C# by Chris Sells, and Jesse Liberty, were invaluable for me. Later, Jon Skeet's book became my first call. You can't go wrong with (the more advanced) books by Michaelis and Lippert, and Andrew Troelsen.

I started programming in 1966 - I kid you not. I learned C in my late 30s, C++ in my late 40s, and C# in my 60s. I am still learning, and not just programming. Never give up. It seems @BillWoodruff may be a year or so older than me.
I never managed to grow long hair, or play the guitar well. So I turned my attention to important life skills such as smoking and drinking. Now as I approach my 74th (a couple of weeks hence) I try to spend more time learning useful stuff that I missed in my younger days.
As to wisdom, thanks for the vote of confidence, but I know I am far from wise.
We all (or most of us) contribute what we can here, and no one person's worth is greater than another's, apart of course, from @OriginalGriff, who knows everything there is to know.
I didn't start programming until I brought a TRS-80 computer apart from usign programmable calculators around the early 1980's.
My first introduction to assembly language was to write the letter 'A' in the middle of the screen.
I had fun with disassemblers in finding out how computer programs worked and learn a few secrets of arcade games.
There were some great games in those days and you had to be skillful to fit you game in a 16k memory space for you had a large market to sell your game.
Typing in computer code from a computer magazine started to be a hobby of mine.
There would not be a lot around in 1966 to program on. It must have been a very large mainframe computers and maybe you used hole punch cards in those days.
If your approx 70yrs old then you must have been started learning at about 17yrs old in 1966 and maybe learning C in 1988.
I'm just starting to learn C# so I have a lot of catching up to do; but in knowing the basics of computers such as loops, logic etc helps.
Yes, punched cards, paper tape, and programming by buttons on the front panel of the processor. I knew nothing about computers when I started my first job, but worked with a guy who taught me the basics. I only learned C# and .NET after I had retired, and there is still much I don't know about it.
I use to save things as bookmarks to my browser but then had a few problems and lost valuable bookmarks so I don't trust browser bookmarks. These days I tend to create shortcuts to a link and store them into a folder that I can backup. In doing this I can arrange the links into sub folders and give easy to identify names.
So start from the beginning and work out where the problem is.
Start by disabling the serial port, and adding random values in your tick handler. Does that do what you wanted - does the graph change each tick?
If it does, then start looking at the serial port.
If it doesn't, then look at the timer, and prove that's working at the interval you expect.
If it is, then look at your graphing package and work out why it's not updating.
If it isn't, then look at why.
Reduce the problem to smaller and smaller areas - it's one of the key parts of both design and debugging!

You need to confirm that you can RECEIVE independently of any charting; and that you can CHART, independent of any receiving. You have done neither. Charting depends (eventually) on receiving. Where to start?
