I started with the first one. Although I wasn't using a database for the chart, I was using a datatable. So I was able to use the info to figure out how to display data in the chart. Then I just played around with a number of things, seeing what happened.

other than those, just add a ChartControl to your Form, and start looking at all the Methods and Properties for it.

start by typing Chart1. in your code editor.

here is a simple example of how to plot data from an array to get you started :)

    Dim values1 As New List(Of Double)
    Dim values2 As New List(Of Double)

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        
        Chart1.Series(0).Points.DataBindY(values1)
        Chart1.Series(1).Points.DataBindY(values2)

     End Sub


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        values1.AddRange(New Double() {10.2, 23.6, 7.5, 9.8, 14.0})
        values2.AddRange(New Double() {5.9, 20.1, 12.8, 16.4, 8.2})

        Chart1.Series.Add("Series2")

        'stacked column style
        'With Chart1.Series(0)
        '    .LabelFormat = "0.0"
        '    .ChartType = DataVisualization.Charting.SeriesChartType.StackedColumn
        '    .IsValueShownAsLabel = True
        '    .BackGradientStyle = DataVisualization.Charting.GradientStyle.TopBottom
        '    .Color = Color.Blue
        '    .BackSecondaryColor = Color.Aqua
        'End With

        'With Chart1.Series(1)
        '    .LabelFormat = "0.0"
        '    .ChartType = DataVisualization.Charting.SeriesChartType.StackedColumn
        '    .IsValueShownAsLabel = True
        '    .BackGradientStyle = DataVisualization.Charting.GradientStyle.TopBottom
        '    .Color = Color.Purple
        '    .BackSecondaryColor = Color.Magenta
        'End With

        'side by side columns
        With Chart1.Series(0)
            .LabelFormat = "0.0"
            .ChartType = DataVisualization.Charting.SeriesChartType.Column
            .IsValueShownAsLabel = True
            .BackGradientStyle = DataVisualization.Charting.GradientStyle.TopBottom
            .Color = Color.Blue
            .BackSecondaryColor = Color.Aqua
            .LegendText = "Values 1"
        End With

        With Chart1.Series(1)
            .LabelFormat = "0.0"
            .ChartType = DataVisualization.Charting.SeriesChartType.Column
            .IsValueShownAsLabel = True
            .BackGradientStyle = DataVisualization.Charting.GradientStyle.TopBottom
            .Color = Color.Purple
            .BackSecondaryColor = Color.Magenta
            .LegendText = "Values 2"
        End With

        Chart1.ChartAreas(0).AxisX.Interval = 1

    End Sub
