Types of Pie Charts

By Attribute	By Classification
In Orbit GIS, an object can hold several records or attributes per Attributeset. Each slice of the pie chart is defined by the (first) value of an attribute. Use this charting technique to graphically represent the value attribute according to the other chosen attribute values per object.	In Orbit GIS, an object can hold several records or attributes per Attributeset. Each record of an attribute set of an object can have one or more values. This means that one attribute record can have several values. Use this charting technique to graphically represent the different values of one attribute per object. Note: this option is not available for attributes of a shapefile, because shapefiles cannot contain more than one value. (Except when an external table with more values is linked to a shapefile, more information see Table Join)
