Developing a charting control
Using VB.NET, voltage values are transferred through the communications port of the computer. How does one take those values (we managed to write a code to/from communication from the communications port) and put it to a live graph, so every 0.25 seconds the graph will graph the voltage?
Instead of reinventing the wheel and developing yet another charting control, I'd recommend that you purchase Dundas Chart
, which is the best of the third-party charting solutions. It will do everything you want and pretty much things you never thought possible.
