A proportional symbol renderer, used to draw symbols of varying size for each feature, sized in proportion to a field value.

Description

Use this renderer to represent quantitative data for features. With this renderer, symbol size is exactly proportional to the data value.

Remarks

An example of using the proportional-value renderer is where you have map tree locations as points and an attribute reflecting the radius of the tree canopy. By using proportional circles, the trees can be depicted by circles reflecting theactual ground covered by the tree.

Another application is a population map; the area of a circular marker can directly relate to the population value.

Proportional symbols also apply well to line symbology; a river could be symbolized with a network of lines with different widths reflecting the river flow.

Known vs. Unknown Data Units

There are really two uses of proportional symbol rendering:

First, you can have a data field that represents an actual distance in the real world, such as the radius of a tree canopy in meters, or the width (actually diameter) of a water main in inches. In this case your units are known and you can use a ProportionalSymbolRenderer to draw a symbol on your map for each feature such that the area occupied by the feature on the map represents the actual area occupied in the real world.

Second, you may have a data field that represents a non-distance quantitiy, for example you might have county data and know the population of each county. This value does not represent a real world distance so the units are said to be unknown. In this case you can use the ProportionalSymbolRenderer to represent the relative population of each county. This is done by mapping a minimum symbol size, specified by MinSymbol, to the minimum data value of the population field. The MinSymbol is then scaled up proportionally based on the relative difference between the minimum population value and the value for a given county feature.

draw

public void draw(IFeatureCursor cursor,
                 int drawPhase,
                 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.

                            AutomationException
Normalized maximum data value.

Description

This property represents the largest possible value in the data. This property does not at all affect the map symbolization, but is only used to help determine the structure of the renderers entry in the table of contents and legend if applicable.

This property is only used if ValueUnit = esriUnknownUnits. In this case the set of symbols to be shown in the renderer legend entry is determined based on the values of these properties: MinSymbol/MinDataValue, MaxDataValue, and LegendSymbolCount which is the desired number of symbols to be shown in the legend entry. Be sure to set these properties before calling CreateLegendSymbol, which refreshes the renderer's legend entry.

If ValueUnit is some known data unit, then only the MinSymbol is shown in the legend and MaxDataValue is not used.

getMinSymbol

public ISymbol getMinSymbol()
                     throws IOException,
                            AutomationException
Symbol used to draw feature with the normalized minimum data value.

Description

This is the symbol used to display the data. This can be a marker or line symbol.

Remarks

MinSymbol is the base symbol used by the proportional symbol renderer, and it can be a line or marker symbol. For each feature in the data, MinSymbol is resized and used to represent the data value in Field. The rules for resizing of MinSymbol are controlled by the settings for ValueUnit and ValueRepresentation.

Marker symbols can be used with both point and polygon data. In the polygon data case, markers are drawn at the center of each feature. BackgroundSymbol provides access to the fill symbol used to draw the actual shape of the underlying polygon features.

getValueUnit

public int getValueUnit()
                 throws IOException,
                        AutomationException
Units of the value field.

Description

This property specifies the real world distance units that the data in Field represent.

Remarks

Known Units

If the data in Field represent an actual distance in the real world, and you know the units for the data, then you should set ValueUnit to these units. For example, for your tree point data you might have measured the radius of each tree canopy in meters and have this stored in the field "Canopy". In this scenario you should set ValueUnit = esriMeters and also set ValueRepresentation = esriValueRepRadius. See ValueRepresentation for more information about how symbols are scaled to data values. Also, in this case you do not need to set MinDataValue.

Unknown Units

If the data in Field does not represent an actual distance in the real world, then you should set ValueUnit = esriUnknownUnits. In this case you need to set MinDataValue to the data value corresponding to the size of the symbol set for MinSymbol.

In the marker symbol case, a feature with value that is twice the MinDataValue will have a symbol with an area twice as big as the MinSymbol. An assumption is made that the marker symbol is square for this calculation. Also, for marker symbols with unknown units, an appearance compensation factor can be applied by setting FlanneryCompensation = True. Empirical testing has shown that people tend to underestimate differences in area when visually comparing two marker symbols. Therefore, this factor increases the difference in area between a smaller symbol and a a larger symbol as the symbols get larger.

In the line symbol case, a feature with value that is twice the MinDataValue will have a width that is twice as wide as the MinSymbol.

getValueUnit in interface IProportionalSymbolRenderer
Returns:
A com.esri.arcgis.system.esriUnits constant
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

setValueUnit

public void setValueUnit(int unit)
                  throws IOException,
                         AutomationException

Specified by:
setValueUnit in interface IProportionalSymbolRenderer
Parameters:
unit - A com.esri.arcgis.system.esriUnits constant (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getValueRepresentation

public int getValueRepresentation()
                           throws IOException,
                                  AutomationException
Representation type of the value field.

Remarks

ValueRepresentation together with ValueUnit specifies how data values are mapped to symbol sizes by the renderer. However, the way that ValueRepresentation affects this mapping is the same regardless of the ValueUnit:

Marker symbols can be proportional by radius or area. Note that marker symbols should be circular or square for these settings to correctly apply.

Line symbols can be proportional by width or distance from the center line (one half the width).

If ValueUnit = esriUnknownUnits, then marker symbols are proportional by area and line symbols are proportional by width.

isFlanneryCompensation

public boolean isFlanneryCompensation()
                               throws IOException,
                                      AutomationException
Indicates if Flannery Compensation is applied.

Remarks

This property is only used if ValueUnit is some known set of units and MinSymbol is a marker symbol.

This property is a flag that indicates whether or not a Flannery compensation factor is applied to the marker symbol sizes calculated by the renderer. By setting this property to True you are enabling the application of this compensation factor.

Empirical testing has shown that people tend to underestimate differences in area when visually comparing two marker symbols. Therefore, the Flannery compensation factor increases the difference in area between a smaller symbol and a a larger symbol as the symbols get larger. It is generally accepted that this factor should be applied when sizing marker symbols proportionally or in a graduated fashion.

                                AutomationException
Number of symbols displayed in the TOC and legend.

Remarks

The ProportionalSymbolRenderer does not use a fixed set of symbols, and so the legend information for the renderer must be refreshed by calling CreateLegendSymbols after changes are made to renderer properties.

This property represents the number of desired symbol sizes to be shown in the legend entry for the renderer. The property is onl used if ValueUnit = esriUnknownUnits. In this case the set of symbols to be shown in the table of contents, and legend if applicable is determined based on the values of these properties: MinSymbol/MinDataValue, MaxDataValue which is the largest possible value in the data, and LegendSymbolCount. Be sure to set these properties before calling CreateLegendSymbol.

If ValueUnit is some known data unit, then only the MinSymbol is shown in the legend and LegendSymbolCount is not used.
