The following program shows, how to get the Excel chart as an image in Picture Box .Before we crate a Chart, we have to fill data in Excel sheet. After enter data your Excel sheet is look like the following picture.

After filling the data, We have to create a chart object in VB.NET and configure the Chart object with necressary data like positions, size, data range, chart type etc.. And use the command for export chart as picture file, then load the picture from the path to picture box. The following picture shows the program screen after drawing the picture


Imports Excel = Microsoft.Office.Interop.Excel
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, _
  ByVal e As System.EventArgs) Handles Button1.Click

        Dim xlApp As Excel.Application
        Dim xlWorkBook As Excel.Workbook
        Dim xlWorkSheet As Excel.Worksheet
        Dim misValue As Object = System.Reflection.Missing.Value

        xlApp = New Excel.ApplicationClass
        xlWorkBook = xlApp.Workbooks.Add(misValue)
        xlWorkSheet = xlWorkBook.Sheets("sheet1")

        'add data
        xlWorkSheet.Cells(1, 1) = ""
        xlWorkSheet.Cells(1, 2) = "Issac"
        xlWorkSheet.Cells(1, 3) = "Raja"
        xlWorkSheet.Cells(1, 4) = "Ravi"

        xlWorkSheet.Cells(2, 1) = "Term1"
        xlWorkSheet.Cells(2, 2) = "80"
        xlWorkSheet.Cells(2, 3) = "65"
        xlWorkSheet.Cells(2, 4) = "45"

        xlWorkSheet.Cells(3, 1) = "Term2"
        xlWorkSheet.Cells(3, 2) = "78"
        xlWorkSheet.Cells(3, 3) = "72"
        xlWorkSheet.Cells(3, 4) = "60"

        xlWorkSheet.Cells(4, 1) = "Term3"
        xlWorkSheet.Cells(4, 2) = "82"
        xlWorkSheet.Cells(4, 3) = "80"
        xlWorkSheet.Cells(4, 4) = "65"

        xlWorkSheet.Cells(5, 1) = "Term4"
        xlWorkSheet.Cells(5, 2) = "75"
        xlWorkSheet.Cells(5, 3) = "82"
        xlWorkSheet.Cells(5, 4) = "68"

        'create chart
        Dim chartPage As Excel.Chart
        Dim xlCharts As Excel.ChartObjects
        Dim myChart As Excel.ChartObject
        Dim chartRange As Excel.Range

        xlCharts = xlWorkSheet.ChartObjects
        myChart = xlCharts.Add(10, 80, 300, 250)
        chartPage = myChart.Chart
        chartRange = xlWorkSheet.Range("A1", "d5")
        chartPage.SetSourceData(Source:=chartRange)
        chartPage.ChartType = Excel.XlChartType.xlColumnClustered

        'exporting chart as picture file
        xlWorkSheet.ChartObjects(1).chart.Export(FileName:= _
        "C:\excel_chart_export.bmp", FilterName:="BMP")

        'load the pipcture into the picture box
        PictureBox1.Image = New System.Drawing.Bitmap _
			("C:\excel_chart_export.bmp")

        xlWorkSheet.SaveAs("C:\vbexcel.xlsx")
        xlWorkBook.Close()
        xlApp.Quit()

        releaseObject(xlApp)
        releaseObject(xlWorkBook)
        releaseObject(xlWorkSheet)

        MsgBox("Chart File Exported !")
    End Sub

    Private Sub releaseObject(ByVal obj As Object)
        Try
            System.Runtime.InteropServices.Marshal.ReleaseComObject(obj)
            obj = Nothing
        Catch ex As Exception
            obj = Nothing
        Finally
            GC.Collect()
        End Try
    End SubEnd Class

When you execute this source code you will get the picture in Picture Box from Excel Chart.

Excellent example! Thanks a ton:-)
One question: Instead of exporting a chart to a file, how to directly display it inside PictureBox using VB.NET? Thanks in advanced:-)
