VBA Excel Draw line between cells based on cell value

0 votes
I'm straining to think of the work. I must draw a line depending on value from one cell to the next (if not 0). There could only be one value in each row; the others are all zeros. Line's beginning and finish were in the cell's middle.

Anyone have programming experience?

In accordance with your description and with the connectors' ends centred on the cells, this code generates msoConnectorStraight forms on the RangeToConnect parameter.
Note: One line controls whether empty rows should be skipped; comment it if you choose.

Sub ConnectValues(RangeToConnect As Range)
    Dim ws As Worksheet
    Set ws = RangeToConnect.Parent
    
    'Clear the existing shapes on the range
    Dim s As Shape
    For Each s In ws.Shapes
        If s.Type = msoConnectorStraight And _
            Not Application.Intersect(RangeToConnect, s.TopLeftCell) Is Nothing And _
            Not Application.Intersect(RangeToConnect, s.BottomRightCell) Is Nothing Then
            s.Delete
        End If
    Next s
    
    'Add the connectors to the range
    Dim cell1 As Range, cell2 As Range, r As Range, c As Range
    For Each r In RangeToConnect.Rows
        Set cell2 = cell1
        Set cell1 = Nothing 'Breaks the line on empty rows, to be commented if they should be ignored.
        For Each c In r.Cells
            If VBA.Len(c.Value) > 0 Then
                Set cell1 = c
                Exit For
            End If
        Next c
        If Not cell1 Is Nothing And Not cell2 Is Nothing Then
            ws.Shapes.AddConnector _
                msoConnectorStraight, _
                cell1.Left + cell1.Width / 2, cell1.Top + cell1.Height / 2, _
                cell2.Left + cell2.Width / 2, cell2.Top + cell2.Height / 2
        End If
    Next r
End Sub
