This post describes a new sample published by ESRI’s Application Prototype Lab and inspired by Jack Dangermond 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 the length/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 this sample updates dynamically even in an edit session.
