Scale Features
The following types of scales are available in the library:
*Rectangular scales (that is, scales with straight-line axes).
*Circular scales (can be used only in polar charts)
The scales can be graduated with:
*Linear graduations
*Logarithmic graduations
Decorations
The following kinds of decorations can be added to a chart to improve its appearance or to help in understanding the data:
*Legends that explain the displayed data
*Grids to help you locate the data points on a chart
*Cursors that show the values of a given data point on the scales of a chart
*Annotations linked to given data points
Grids, cursors, and annotations are all part of the chart. A legend is a separate graphic object that can be positioned independently of the chart.

*Data interactors that allow the user to do the following:
