A common task done in macros is to lock and unlock different cells and objects in a workbook. This is often done for protection reasons, so that things cannot be modified inadvertently by users. If you need to unlock the charts that are in your workbook, you can easily do so if you remember that even though charts can be considered drawing objects, you don't unlock them as drawing objects--you specifically unlock the chart object.
In addition, how you unlock a chart depends on whether it is a Chart sheet or a Chart object on a regular worksheet. The following code, named ChartUnProtect, provides an example of how to successfully unprotect both types of charts.
Sub ChartUnProtect() Dim wks As Worksheet Dim cht As Chart Dim chtObj As ChartObject Dim PW As String PW = "mypass" 'Unprotect all Chart sheets For Each cht In ActiveWorkbook.Charts Sheets(cht.Name).Unprotect password:=PW Next 'Unlock all Chart objects on each worksheet For Each wks In ActiveWorkbook.Worksheets wks.Unprotect password:=PW For Each chtObj In wks.ChartObjects wks.DrawingObjects(chtObj.Name).Locked = False Next wks.Protect password:=PW Next End Sub
