I don't know if this will help.
I published a Terminal program for a PC with source code in C#.
Besides the program accepting and sending characters to a remote UART device such as on the PSoC, it also can accept data in packetized form to plot on the PC and/or log into a .csv format.
This program is free and since it has the source code, can be altered by anyone as they need.
I've used this program in a long-term battery study and used both the plotting and logging functions.

Thank you for your reply. I am plotting the adc result to a terminal monitor and more specifically to the Putty, through the SW Tx UART. So, I extract the results from the Putty to a txt file and afterwards, I import the data to an excel file. I think this way is more helpful to me.
Thank you 🙂
