The Apache ECharts app demonstrates techniques to enhance data visualization of PowerBuilder with open-source JavaScript charting engines. It is developed with Appeon PowerBuilder 2021 and compatible for deployment as traditional client/server, PowerClient, or PowerServer 2021.

Key Techniques Demonstrated:
  • Applying WebBrowser control
  • Embedding Apache ECharts
  • Integrating JavaScript with PowerScript

A good example application that shows how one can implement the use of Apache ECharts in a PowerBuilder app. Thank you, Appeon, for creating and publishing this application!

Downloaders, please be aware that the enhanced web browser control (n_webbrowser in echarts_base.pbl) creates a JsonGenerator object in ten of the twenty-four "of_createoption..." object functions without destroying them. Normal garbage collection should reclaim the memory used for these objects, but it's always best to explicitly destroy manually-instantiated objects.
