There is a possibility of making a simple chart on such a large scale that the mere size of the chart adds to its complexity by causing the reader to glance from one side of the chart to the other

Fig. 239. A Clear and Accurate Title is of Great Importance

The clipping above, taken from the front page of a very prominent newspaper, shows an absurd title. If a thing is reduced 100 per cent, it is all gone. How can drinking be reduced 2,000 per cent.?

Any conventional symbols or signals adopted for use in graphic work should be as clear and suggestive as it is possible to make them. The above illustration is shown here as an admirable example of good practice in the making of graphic symbols

in trying to get a condensed visualization of the chart. There are relatively few curve charts which cannot be presented for report purposes on paper 8j^ by 11 inches, the commonest size used for a typewriter. Though the placing of a chart on paper of typewriter size requires more care than is necessary if a very large sheet of paper is used, the resulting chart is frequently more easy to interpret than it would be if made to a larger scale.
