Displaying x-axis labels by interval

By default, a chart displays every category value on the x-axis, unless the label does not fit in the space allocated evenly to each category value. As described in the previous sections, to make all the labels fit, you can display the labels at an angle or stagger the labels. These techniques, however, can make the x-axis look crowded. If it is not essential to display every category value, you can specify that the x-axis display alternate values, or every third value, and so on.
