Chart - ligacao a base de dados

Recommended Posts


Boas pessoal,

Eu quero que o meu chart me mostre dois campos de uma tabela, mas não estou a conseguir programa-lo, estou a fazer assim

Const cs As String = "Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\Acer\Documents\Visual Studio 2010\Projects\Empresa2\Empresa2Teste.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"

Dim con As New SqlConnection(cs)


Dim novonome, novaquantidade As String

Dim sql As String = "SELECT * FROM Artigod WHERE Nome='" & novonome & "', " & "Quantidade='" & novaquantidade & "'"

Dim sqlcom As New SqlCommand(sql, con)

Dim da As New OleDbDataAdapter(sql, con) <-- da erro de que o tipo nao esta definido

Dim ds As New DataSet()

da.Fill(ds, "Artigos")

Dim ChartArea1 As ChartArea = New ChartArea() <-- da erro de que o tipo nao esta definido

Dim Legend1 As Legend = New Legend() <-- da erro de que o tipo nao esta definido

Dim Series1 As Series = New Series() <-- da erro de que o tipo nao esta definido

Dim Chart1 = New DataVisualization.Charting.Chart()


ChartArea1.Name = "ChartArea1"


Legend1.Name = "Legend1"


Chart1.Location = New System.Drawing.Point(50, 50)

Chart1.Name = "Chart1"

Series1.ChartArea = "ChartArea1"

Series1.Legend = "Legend1"

Series1.Name = "Series1"


Chart1.Size = New System.Drawing.Size(750, 500)

Chart1.TabIndex = 0

Chart1.Text = "Chart1"

Chart1.Series("Series1").XValueMember = "Nome"

Chart1.Series("Series1").YValueMembers = "Quantidade"

Chart1.DataSource = ds.Tables("Artigos")
