The Gekko graphical user interface (GUI) is developed in a modern programming environment (.NET), and ease of use of the GUI is a key priority. This concerns both the GUI and the Gekko command language. The goal is to provide a smooth and productive user experience, so that the user can concentrate on the real issues (the models, data, scenarios, etc.).

Gekko graphical user interface (main screen)

 

main Gekko window has three tabs ('Main', 'Output' and 'Menu'). The Main tab is shown in the above screenshot, and this tab is divided vertically into a user input section for Gekko commands (below) and Gekko output (above). If this output is bulky, Gekko may direct it to the 'Output' tab. The Menu tab is for showing user-designed menus (and tables). The bottom bar shows the current global time period, loaded databanks, and current working folder. At the right-side of the bottom bar is a job status indicator.

Graphs in Gekko are made via gnuplot (embedded in the Gekko installation).
