A pin is where features are bound to a chart definition. The chart type defines how many pins a user can add to a chart definition and it also defines how many features can be connected to a single pin. Each pin has a UConfiguration. Pins and the associated UConfiguration are stored with the chart definition.
A pin is always typed with a feature type. Typing can be defined by the chart type or can be a setting of the pin. A pin can therefore connect features of one specific feature type only. If typing is a pin setting the chart type may restrict the feature types that can be used by defining characteristics a feature type must have. E.g. feature types with at least one numeric property on the first level of the observation property structure.
Charts support two different types of pins. Regular pins and Report pins. The user can connect features only to regular pins. Report pins are used by the reporting engine to dynamically create charts for a series of feature.
