Description

The LabelOptions() function offers numerous ways to position and finely adjust labels:


• Location of the Labels on Non-Stacked Bar Charts

If enough space is available, the labels are placed by default outside of the bars, otherwise on the inside. Using the argument location, nine positions can be defined on bar charts.

In addition, it is possible to represent either the total sums or the running totals. The drawing and positioning of (running) totals are controlled by the four style functions LabelTexts() , LabelStyle() , LabelBackground() and LabelOptions() in combination with seriesIndex =​ –1 (or seriesIndex = stacked). This special series index is available only in the four above-mentioned style functions in combination with stacked or proportional charts. The (running) totals can be placed either outside (default) or on the border of each individual bar or area section. Four constants are available for the argument location. The other usual positioning constants are ignored when seriesIndex =​ –1 (or seriesIndex = stacked).
