Is it possible to add text to a chart in Calc

I have various charts of data and would like to add text comments to highlight issues on the chart. Is there any way to do this?

Have a look at the following.

Inserting & Editing Comments…

Thanks for your answer. I want to add comments to my chart. But your link to adding comments to a sheet is useful. Thanks.

If the chart is in edit mode, you can use its drawing toolbar. Not all shapes are available, but you will find a “Text box” and a “Callout”. The drawings are put in front of the chart elements. If the drawing toolbar is disabled, go to menu View > Toolbars > Drawing.

Wow Thanks. It worked.

Exactly the info I was looking for, thanks.

For anyone who wonders the same as me: there is a long open bug with the font size of text, using the text box from the drawing toolbar in Calc: https://bugs.documentfoundation.org/show_bug.cgi?id=83159

This also answers my question. Thank you.
However, when you remove the chart from edit mode the text disappears.
Same thing happens when you add a Line.
