Hi experts,

I am using C#.
I want to draw a real time graph. I am getting data from serial port which I want to take as Y axis and X axis will be real time. I don`t know how to draw such a graph (serial data vs time).

The data I'm reading from serial port is temperature.

Please tell me if anyone knows how to do it or please send me example code. It's very important for me. Please help.

Thanks in advance

Wow, real time graph is a bold requirement. Have a look at Cédric's charting control [^], it is "high speed".

You may also give a try to CodeProject article search engine.
For instance, a quick search gave me this entry: "Cristi Potlog's Chart Control for .NET".

See this article here, it is based on a temperature sensor conntected to an Arduino, which then pumps the data via serial port to a PC.

It is VB.net but should be easily ported to c#.
