# Annotation

## Content



The annotation along each axis is an important part of any chart. The chart annotates the axes with numbers based on the data/values entered into the BubbleSeries, DataSeries, HighLowOpenCloseSeries, HighLowSeries, or XYDataSeries objects. Annotation for the Axes will always display basic text without any formatting applied to them.

The chart automatically produces the most natural annotation possible, even as chart data changes.
