Why is it that when I double click a graph in Calc, the ribbon at the top disappears? For example, I would like to enter superscripts/subscripts when editing titles, but there seems to only be a work-around by making a text box, editing the text in there with the full suite of formatting options, and then copy-pasting into the title. Also it is irritating that when you double click on the chart to enter edit mode, the y-position of the spreadsheet is shifted upwards, since the header of the edit mode is shorter than the header in the standard mode.

Thanks for your help and consideration. Ian
