I'm trying to link a chart to another workbook in excel 2010. Copy-Paste does the trick, except for the dates on the horizontal axis. They keep showing as numbers (42515), but not in date format. I tried several things: change Axis type, convert source data to text (TEXT(42515; "dd/mm/yyyy")...
It's necessary that the link between the two charts stays, because I use it to automatically update the chart.
Anyone any suggestions?
