You can right-click a Table Graph plot node to add a Filter subnode (), which controls which columns or rows in the table to include. The Filter node has the following section:

Under Point Selection, enter the columns (for column-based table data) or rows (for row-based table data) to include in the table graph in the Logical expression for inclusion field. You enter them as comma-separated entries such as col1, col2, … for column-based table data. In the Logical expression for inclusion field, you can also use rowindex to refer to the row index (for example, in a Boolean expression like mod(rowindex,3)!=0) with column-based table data and, similarly, colindex to refer to the column index with row-based table data.
