how to give data labels only for x axis points, eg once a week

My graphs have daily Covid data; necessary for graph but not for data label. So how to show data labels only for x axis points, eg once a week?

If you can’t show us an example, please tell us at least what kind of graph you are using : bars, columns, line graph, x-y scatter, etc?? Please edit your question above to add this information. You should also add the version of LibreOffice that you are using.
