Hi,

Programmatically, how would i refer to the Chart Source data that is in
another Workbook please?

Currently i have:
ActiveChart.SetSourceData
Source:=Workbooks("Cases_Older_Than_One_Year.xls") .Sheets("Charts").Range("A3:" & Mycol & "6"), PlotBy:=xlRows

When Cases_Older_Than_One_Year.xls is open it works fine (as i would expect)
but i would rather not have to have this WB open at this point in the macro.

Thanks

John

The following code is an extract from a program that was extensively
used for auto-assigning ranges to plots. All you need to do is toggle
between target and source file to get the data.

Also, please remember that the code is highly dependent on the file
layout. Please make the necessary change when targeting various sheets
& files.

Have fun

Where is the closed workbook that the OP asked about?

A workbook must be open for a chart to change a reference to a worksheet
range within that workbook. An existing reference to a closed workbook is
fine, as long as the reference is not edited.
