Fig. 238. Statistical Exhibits in the Municipal Parade by the Employees of the City

of New York, May 17, 1913

Many very large charts, curves and other statistical displays were mounted on wagons in such manner that interpretation was possible from either side of the street.

The progress made in recent years by practically every city department was shown by comparative models, charts, or large printed statements which could be read with ease from either side of the street. Even though the day of the parade was rainy, great crowds lined the sidewalks. There can be no doubt that many of the thousands who saw the parade came away with the feeling that much is being accomplished to improve the conditions of municipal management. A great amount of work was necessary to prepare the exhibits, but the results gave ample reward.

Chapter XVII A FEW CAUTIONS

THE title for any chart presenting data in the graphic form should be so clear and so complete that the chart and its title could be removed from the context and yet give all the information necessary for a complete interpretation of the data. Charts which present new or especially interesting facts are very frequently copied by many magazines. A chart with its title should be considered a unit, so that anyone wishing to make an abstract of the article in which the chart appears could safely transfer the chart and its title for use elsewhere. In the preparation of this book it has been found that a number of the charts used have been copied from one magazine to another, and that the titles under the charts have suffered much in the copying.
