Chart(s) refers to visual representations of data. Use the “Chart” button at the bottom of any data window (i.e., grid) (e.g., products, orders) to make visual reports of the grid.
Charts are not created based on just a table without specifications. There must be at least one grouping and one aggregate chosen in the grid from which a chart can be created, the chart button will show no data. Group by dragging a column to the top of the window. And choose an aggregate in another column by clicking on the three dots next to the title of the column.
