There is a nice tool un Windows Forms called Chart. You can draw graphs of different kind with it.

Here is a Tutorial

Here is a Video that shows how to use it.

Here is a nice post with an example from StackOverflow.

Have fun exploring it.

Basically the steps are:

1. Create a Series for each line you want to draw.

2. Add the values from your array or list to the series.

EDIT: 3. See comment by TaW

EDIT 2) : here you find all different chart types that can be displayed.

and here how to use them.

When you click in the property window of the chart on Series you get the Series-Properties. There you can also find the property: ChartType and set it by a mouse click if you want to.

You'll have to create the port object and set the necessary parameters for it from the design view search for port tool

or your code like this

dataPort.PortName = your_port_name;
dataPort.BaudRate = your_baud_rate;

After you open the port and read the data from it:

dataPort.Open();

while(dataPort.IsOpen)
{
    chart1.Series["Series1"].Points.AddXY(val.Second, dataPort.ReadByte());
    chart1.Update();
}
