; NAME:
;  mms_ui_gen_overplot
;
; PURPOSE:
;  Widget wrapper for mms_overview_plot used to create MMS overview plots in the GUI
;
; CALLING SEQUENCE:
;  success = mms_ui_gen_overplot(gui_id, historyWin, oplot_calls, callSequence,$
;                                windowStorage, windowMenus, loadedData, drawObject)
;
; INPUT:
;  gui_id:  The id of the main GUI window.
;  historyWin:  The history window object.
;  oplot_calls:  The number calls to mms_ui_gen_overplot
;  callSequence: object that stores sequence of procedure calls that was used to load data
;  windowStorage: standard windowStorage object
;  windowMenus: standard menu object
;  loadedData: standard loadedData object
;  drawObject: standard drawObject object
;  
;
; OUTPUT:
;  none
