label parallel to the Y axis. Parallel labels should read from bottom to top.
· Axis labels should be placed close to the scale numbers, but not so close that they protrude into the imaginary rectangle occupied by the scale numbers.
· If there is more than one Y axis, the labels should all read in the same direction(from bottom to top). It is helpful to include the data point or line pattern in the Y-axis labels to show which data relate to which Y axis.
· Numbers along the Y axis should be horizontal and aligned on the decimal point, whether or not the decimal point is actually present. Figs. 21 and 22 compare the incorrect (Fig. 21) and correct (Fig. 22) usage of label placement. Size of Labels
· The axis label should be large enough to be legible but not so large or heavy that it competes with the chart content for attention. Numbers should be smaller than the axis label size. The title should be larger than the axis labels. Explanatory labels, such as a legend, should be smaller than the axis labels.
· Boldfacing or increasing the text size of the headings can help to differentiate them from the body of the table. Use larger font sizes instead of boldface text.
· For posters, text needs to be large enough so that the audience can read it
