If the horizontal bars are arranged with the earliest date at the top, any reader who wishes to do so may read the chart as a curve from the left-hand edge of the page and the dates will then appear in correct order from left to right.

In Fig. 45 the latest date has been placed at the top of the chart. This causes an impression absolutely the reverse of what it was intended to bring out by the drawing. Any one glancing at this chart is likely to suppose that the earlier year is indicated at the top and probably would not notice that the draftsman in this case, for some unjustifiable reason, has reversed the correct arrangement.
