A unique values renderer where symbols are assigned to features based on an unique attribute values.

Description

Use this object to symbolize features based on the values of one or more attribute fields to show categorical difference.

Remarks



Use the UniqueValueRenderer to display feature data that falls into distinct categories based on attribute values. For example, if you have parcel data with land use types of residential, agriculture, and retail, you can use a different symbol to represent each unique land use type.

Each unique value can define a unique category, represented with a single symbol, or values can by combined by grouping so that more than one value is symbolized with the same symbol. Grouping is implemented by utilizing IUniqueValueRenderer::ReferenceValue. Also, headings can be used to organize categories in the table of contents and legend, see IUniqueValueRenderer::Heading.

Unique value renderering is typically based on a single attribute field, however up to 3 fields can be used. When more than one field is used, the combinations of the unique values from each field are used to define the categories. So, for example if two fields are used which store the values A and B; and X, Y, and Z respectively, then the initial categories will be defined as A|X, A|Y, A|Z, B|X, B|Y, and B|Z.

              throws IOException,
                     AutomationException

Adds a value and corresponding symbol to the list. For multivariate cases, the specified value is a delimitted list of individual values.

Description

Adds a value and symbol to the list of unique values.

Remarks

After setting FieldCount and setting at least one Field, use this method to add a unique value and corresponding symbol to the renderer. You can later retrieve and/or change the symbol for particular value using the Symbol property.

If you pass a Value that already exists in the renderer, then the existing symbol for the Value will be replaced by the object passed as the Symbol parameter.

If FieldCount > 1 then the Value you pass should be a list of values, one for each field, separated by the FieldDelimitter. By default this is a comma.

To add a value to the renderer, and have that value be drawn with the same symbol as another existing value or values, use AddReferenceValue instead of AddValue. When more than one value is drawn with the same symbol, the values are said to be grouped.

Null Values

At ArcGIS versions 8.2 and later, special behavior was added to the UniqueValueRenderer to handle Null values. If you add the special value "<Null>" to your renderer and your database supports Nulls, then features where Field = Null will be drawn with the "<Null>" symbol.

The "<Null>" symbol may also be used in table join situations. With joins that keep unmatched records, ArcMap inserts artificial Nulls into the virtual join table. Features with these values will also be drawn with the "<Null>" UniqueValueRenderer symbol.

International users working with a localized version of ArcGIS should add the localized version of the string "<Null>" to get the special behaviors described above.

See the associated Example to see how to scan a feature class for unique values and then add them to a UniqueValueRenderer.

draw

public void draw(IFeatureCursor cursor,

                 IDisplay display,
                 ITrackCancel trackCancel)
          throws IOException,
                 AutomationException

Draws features from the specified cursor on the given display.

Remarks

This method is typically called by the framework to renderer features to a display. This could be in response to a refresh on the map. This method typically iterates through all the features and renders each feature with an appropriate symbol.

An individual feature is typically drawn by calling the Draw method on the feature's IFeatureDraw with the symbol created by the renderer. However, when writing a custom feature renderer you can draw anything you want using a number of different methods. To learn more see the section on writing a custom feature renderer in Extending ArcObjects.

To allow complex rendering to be canceled halfway through a draw, the renderer typically checks the TrackCancel object after each feature or set of features. If a cancel action has occurred, the renderer will exit.

There are three drawing phases: selection, annotation, and geography, and this method can be called by the framework up to three times. With the exception of the selection phase, this method will only be called for a particular draw phase if the call by the framework to RenderPhase returns true for that phase.

Feature renderers typically only draw features during the geography phase, though in some cases features are drawn in the annotation phase. Take for example a case where proportional symbols are drawn for polygon features. The ProportionalSymbolRenderer draws the background fill symbol during the geography phase and the proportionally sized marker symbol during the annotation phase.
