shows the chart (timeline) area of the Gantt chart
//hides the timeline area of the Gantt chart gantt.config.show_chart = false; gantt.init("gantt_here");
gantt.config.show_chart = false is useful when you need to hide the timeline area of the Gantt chart quickly while gantt.config.show_grid = false serves to hide the grid area. If you work in a simple layout, you'd better not use these two options together as it may cause an unexpected result. Instead of it, you should change the configuration of the layout via gantt.config.layout.
