I'm totally new to C#, in fact any coding language. I've written a code which takes values (Temp and Weight) from Serial Port (COM Port) and store those values in DataGridView1. Now, as values written to the DataGridView1, I want them to plot on graph using LiveChart Nuget Package.

If line graph can be done on separate form then it's really good for me. If not, at least suggest me to plot a line graph on same form. Please refer below image for the output:

Note: X Axis value (Weight) start from 100 and ends at 0.

You have 3 "components":

1) One to collect the data into a queue / collection. (e.g. BackgroundWorker)

2) Another that updates the Grid

3) Another that updates the chart.

If #1 uses an observable collection, #2 and #3 can subscribe to the update events (implicitly via an ItemSource, or explicitly via event handlers), and update their UI in turn.
