Time = x, survival = y, and group = group (if you have groups). You will want to exclude, delete, or filter out (local data filter) the combined table values. Use the line element (the one that connects each point). You can also shift and select the points to have both the points and lines, you might want to see the points to get the labels on then turn them off. The table will have "time" as the label (see the little label in the column name). Right click on that column header and select Label/unlabel to remove. Then right click on the At Risk column header and select Label/Unlabel to indicate that is the column you want to use as the label. Now any row that you want labeled in your plot, select the row and then from the row menu select label. Or click the point in the plot, right click and select Rows>Row Label.
In graph builder you can also take the ? tool and click in the graph and that will get you to the sections in the help about the GB.
