Visual Basic provides a ready-made Control for charting and graphing.
All we need to do right now is add it from the Toolbox.
In Visual Basic, click on the tab that says "Form1.vb [Design]", so
you are looking at the Form1 design. In the Toolbox, click on the Chart
Control, which is grouped under Data. Then click anywhere on the background
of Form1 to add the Chart Control to Form1.
Set the Size Property of the Chart to 819, 450, and use your mouse
to position the Chart directly under the lowest Panel.
Set the BackColor Property to Gainsboro (or any other color you like)
to make the chart stand out from the background.
Click on the background of Form1, and use the Form1 size "handles"
with your mouse to make the Form large enough to contain the Chart Control.
You may need to scroll the Visual Basic window in order to see the bottom
of the Chart Control and the Form.
Visual Basic Design mode shows the chart control with a default bar
chart as shown in the picture. We will actually be using line graphs,
but that will be set up later in code.
