Introduction
I made this control as a favor to my friend who is an electrical engineer. He needed a Task Manager style control to display a sampled signal coming from a device that he was making. I did a quick search on codeproject, and the closest thing I could find was Anup. V.’s Plotter control but it lacked the scrolling capability. So I finally had to get my hands dirty and made this plotter control. Now I’m posting it here guessing that there might be other electrical engineers out there who are in a desperate need of such a control.

Tip: Use the vertical track bar to change the current value.
Using the Plotter Control
-
Set the Min & Max properties.
-
Set the BackColor & ForeColor properties to adjust the colors to your liking.
-
Use the Add method to add new values periodically (e.g. from a timer event handler).

Fixed a bug when the graph was drawn incorrectly when the control was put on a form with AutoScaleMode different than None and the system font size was different from the size the application was built with.
