Collabora Office 23.05 Help
To edit a chart title that you have inserted into a Collabora Office document:
Double-click on the chart.
A gray border appears around the chart and the menu bar now contains commands for editing the objects in the chart.
Double-click on an existing title text. A gray border appears around the text and you can now make changes. Press Enter to create a new line.
If no title text exists, choose Insert - Titles to enter the text in a dialog.
A single-click on the title allows you to move it with the mouse.
If you want to change the formatting of the main title, choose Format - Title - Main Title. This opens the Title dialog.
Select one of the available tabs in the dialog to make modifications.
Click OK. In your document, click outside the chart to exit chart editing mode.
