A common method of including supporting data is to place the figures in the form of a table above or below the grid opposite the vertical rulings, reading upward as shown in the chart at the top of the page. This method has the advantage of closely relating figures to the plotted points.

TABULAR INSERTS. Supplementary or supporting data can often be shown as a tabular insert placed within the grid where adequate space is available. This procedure is particularly good where it is desired to include figures but at the same time subordinate them to the graphic picture.

COORDINATE TABLE AND CHART. Where the tabular presentation is of equal importance to the graphic, it is frequently a good plan to construct a separate chart and table, placing them side by side.

4. SIGNIFICANT DATA ONLY. Data added to clarify the picture should generally be restricted to the items in which the reader is most likely to be interested, such as high or low points on fluctuating curves or the values for recent dates. In coses where such values ore included directly on the curves, the principles outlined under "Curve Designations," pages 52 and 53, should be observed.

5. A Grid with frequent horizontal rulings may often make the reading of amounts sufficiently precise to obviate the need for actual data.

The arrow and designation "Edge of Paper" have been added to the original in order to indicate that the outside line is not a frame. See 382.
