Change Source Data in VBA
Hi,
Please be aware that I have also posted this in the XL Programming group as I am not sure which is most appropriate. I have a chart set up (eg a simple bar chart) that I want to be able to update automatically using VBA. The source data will vary in quantity and I have no way of knowing in advance how many data there will be. Eg I might currently have: A1 B1 C1 D1 10 12 15 35 but when I want to refresh the chart I might have: A1 B1 C1 D1 E1 F1 15 5 10 20 25 10 (don't worry about the actual values). How do I tell Excel to re-size the source data area automatically (ie as part of a VBA macro) - the number of data may reduce as well as increase? I'm reasonalby comfortable with VBA but by no means am I a programmer, so a brief explanation of how the solution works would be appreciated. This is in Office 2003 if that makes a difference. TIA Dave |
Change Source Data in VBA
Before tackling this process using VBA, would it be possible to solve with a
dynamic range? http://peltiertech.com/Excel/Charts/Dynamics.html In your scenario, perhaps a range defined something like: =OFFSET($A$1,0,0,COUNT(1:1),1) named "MyRange" In your chart, the data range is: ='My Book.xls'!MyRange -- Best Regards, Luke M *Remember to click "yes" if this post helped you!* "Risky Dave" wrote: Hi, Please be aware that I have also posted this in the XL Programming group as I am not sure which is most appropriate.
