Understanding such differences helps in balancing team structures and assigning developers to pending issues or hiring developers. In this extended abstract, we demonstrate how simple APIrelated, per-developer metrics can be visualized to give a quick overview on the API experiences of developers. Data extraction is based on mining the commit history in projects in terms of references to API elements (methods and types). We visualize experiences as maps and aster plots.enProgram ComprehensionSoftware VisualizationMining Software RepositoriesDeveloper Experience.Text/Journal Article0720-8928
