For the following exemple, we want to drop a chart if a dataset is empty.
Include the Carbone tag {d.values:ifEM:drop(chart)} within a shape alternate text, title or description.
the d.values is a list of values to create a chart, coming from a JSON dataset
the :ifEM is a conditional formatter checking if the list is empty.
the :drop(chart) formatter is fired if the previous condition is true. The first argument chart is required to defined the element to drop.

Locations to insert tags for:
LibreOffice: Right click on the chart > properties > Option tab > Insert the drop expression {d.values:ifEM:drop(chart)} in the name, text alternative or description field
MS Word: Right click on the chart > click on "edit alt text" > insert the drop expression {d.values:ifEM:drop(chart)}
