Add new data to chart

New to LibreOffice. How do I add new data points to an existing chart.
Instructions say I must add a tag. I have no idea what a tag is. Please explain.

For what it’s worth, I have never seen a more unusable Help than LibreOffice offers. Maybe I’ll get used to it.

Hi

You can add data points with drag and drop. The “trick” is to select the data set (not just the new points) and then drag and drop them on the graph.

Anyone is welcome to help improve the documentation. Do not hesitate if you have good ideas :slight_smile:

How do I select the data set?
