Representing Dynamic Chart for Survey Data

Whenever you need to draw dynamic chart in a userform depending on parameters & factors of survey as mentioned above,VBA macro code is mentioned below.You will have to select one parameter at a time mentioned at the left hand side of the chart.The only requirement for this code is to set focus of your cursors on data points on an excel spreadsheet and to load an image control in form

Private Sub UserForm_initialize()
Call showGraph

End Sub


Sub showGraph()
Dim currentrow As Long
Dim currentchart As Chart
Dim pathname As String
Dim chartheader, datasource, chartdatasource As Range
   currentrow = ActiveCell.Row
    On Error GoTo Errorhandler

    If currentrow <= 1 Then
       MsgBox "Move cell pointer to a row that contains data of Row Labels"
    End If
   
    Set chartheader = ActiveSheet.Range("A1:F1")
    Set datasource = ActiveSheet.Range(Cells(currentrow, 1), Cells(currentrow, 6))
   
    Set chartdatasource = Union(chartheader, datasource)
   
    Range(chartdatasource.Address).Select
    ActiveSheet.Shapes.AddChart.Select
   
    ActiveChart.SetSourceData Source:=chartdatasource, PlotBy:=xlRows
    ActiveChart.ChartType = xlColumnClustered

        pathname = ThisWorkbook.Path & "\temp.gif"
        If Not Dir(pathname) = "" Then
               Kill pathname
            End If
    ActiveChart.Export Filename:=pathname, filtername:="gif"
   
   
    pathname = ThisWorkbook.Path & "\temp.gif"
    UserForm1.Image1.Picture = LoadPicture(pathname)
   
        ActiveSheet.ChartObjects.Delete
   
   
    Exit Sub
Errorhandler:
