Under this tab you can see and replan the activities in a so-called Gantt chart.
You can for example enter a Start date, select Scale type and configure a desired Cell width. By using the check box Replan automatically you can get an automatic replanning after changing the Start date and End date for the activities.
At the very bottom you will find buttons to use for scrolling in the lead time chart and another button to use for printouts of the chart.
