This post describes a new sample published by ESRI’s Application Prototype Lab and inspired by Jack Dangermond’s geodesign presentation at the 2009 ESRI International User Conference.
Dynamic Charting for ArcGIS Desktop is a free sample (with source code) available from the ESRI code gallery. The sample summarizes a layer’s features based on length or area and grouped by unique values from the renderer. The differentiating factor between this sample and the out-of-the-box charting tools is that these charts update dynamically, even during editing operations.
The screenshot below demonstrates the Dynamic Charting tool in use during an active edit session. As the user digitizes landuse lines and polygons, pie charts summarizing these two layers are automatically updated. The benefit of this sample is that it allows the ArcMap user to view the proportion of features, for example, major roads versus minor roads, easily and dynamically.
