chart function worked, then grayed out
I have a spreadsheet with about 800 rows and analyzing text data using countifs. I've already done a bunch of charts this way, just tried one and got a nice stacked column chart but it did not have the axes labeled. I looked at the way I had done previous charts and then included the axis titles in the range I selected to make the chart. Now ALL my chart functions are grayed out and I cannot make a chart!! I cannot even make a chart with a simple selection of table number values without the axis labels. What is going on??
