You can choose the time scale by selecting a scale on the task bar, or by using the and icons to zoom in or out. The time scale can be selected from the list box. Display settings for the calendar, such as the formatting and the column width, can be configured for individual scales. Any changes to those settings are automatically stored for the scale you are editing.

Use the icon to print the Gantt chart. To include headers or footers, select View menu, Gantt chart settings, Properties, Headers and footers tab to set the options of your choice.

To display a project line in the Gantt chart, select the project line in the project tree. Use the icon to position the selected line on the form with the start date on the left-hand side of the Gantt chart.

This function is also available for production files and operations. For those items, lines are positioned automatically, however. Projects are not positioned automatically, because in large projects with many relationships it is difficult to follow relationships. For production files and operations, it is usually not that important to follow relationships.

Use the date field to set the first date shown in the Gantt chart. The Gantt chart displays project lines as from that date.

To change the start and/or end date of a project line, you can move, extend or shorten bars in the Gantt chart.

Bars can be moved to an earlier or later time in the diagram.

In the Gantt chart, bars can be extended or shortened. The only way you can do this is by moving the end date to an earlier or later date. The start date cannot be changed in the Gantt chart.

For project lines, the plan type must be 'Estimated'. For project lines with underlying lines or with linked orders, a summary is displayed of the underlying or linked data. To make a change, you need to change the underlying line or linked order.

Right-click to change the properties of the Gantt chart. The settings of the Matrix tab on the Gantt chart properties form apply to all time scales. The settings on the other tabs apply to individual scales. In the Date format field, choose how you want the dates to be displayed.

Date format

To restore the settings or properties of the Gantt chart or projects to their defaults, use the Reset Gantt settings and properties process.

Line data can be changed directly from within the Gantt chart. Double-clicking the line you want to change in the Gantt chart will open the Custom form in the Edit mode. You can customize this Custom form with any fields you want to be able to change directly from the Gantt chart.

You can expand or collapse every individual line with underlying levels, or you can expand and collapse multiple lines at the same time. Use the plus (+) and minus (-) buttons to open or close the lines and their underlying lines.

When a project or production file has been expanded, the different lines are shown underneath each other. When a line has been collapsed, only the information of the actual line itself is shown. To display the lines side by side, click the  icon. This allows you to view the entire project with subprojects or the entire production file tree at detail level. This view is particularly useful for consecutive lines, as overlapping lines are superimposed, which reduces the clarity of the information.

Use the icon to show or hide relationships with successors in the Gantt chart.

You can create successors (or subsequent operations, in the case of operations) by dragging the predecessor to the successor. The place from which you drag the item and the place at which you drop the item together determine the relationship type:

• Drag item from second half and drop it on the first half: End - Start
• Drag item from second half and drop it on the second half: End - End (projects only)
• Drag item from first half and drop it on the first half: Start - Start (projects only)

It is not possible to drag an item from the first half and drop it on the second half. To undo successor relationships, repeat the link operation.

Use the icons to move a project line up or down in the project tree.

Click the icon to move the selected project line down one level. This will make the project line part of the line above the selected line. This change is also applied to the Component of field on the General tab. To make the line part of a line other than the line above it, you need to enter the parent line in the Component of field on the List tab or the General tab.

Click the icon to move the selected project line up one level, so that the selected line will become part of the first project line above it that is one level above the selected line. This change is also applied to the Component of field on the General tab. To make the line part of a line other than the line above it, you need to enter the parent line in the Component of field on the List tab or the General tab.

You can change the progress percentage of a project line if the cursor contains '%'.
