I have a file of 28 charts that is linked to 12 spreadsheets utilizing the
€œsource data€� function within Excel. The spreadsheets are updated weekly (at
a minimum). When the chart files are opened, a pop-up asks if you want the
charts to update or not. I select the €œupdate€� option to update the charts
with the new data from the spreadsheets. This particular set of data was
entered on 6/22 and then again on 6/29. When I updated the charts, they all
updated with the new data with the exception of 4 charts linked to one
spreadsheet. All 24 other charts linked to the other 11 spreadsheets
displayed the 6/29 data. The 4 charts only show data to the 6/22 date, even
though the spreadsheet includes the 6/29 data.

I have checked all formulas associated with these charts and they are
formatted exactly as the formulas that updated. When the €œsource data€� is
opened and the series is viewed, it encompasses (dotted line circling the
data column) the 6/29 data. I can see no logical reason for this one
spreadsheet not to update the 4 charts.
