Gantt charts
Focal Point® provides improved visualization options in the Gantt chart. Gantt charts provide options like displaying histogram with time grid attributes and threshold line, copying chart to the clipboard, generating or printing reports from the chart, and support for graphical settings. A Gantt chart is a horizontal bar chart that displays activities and the possible relationships between the activities. Gantt charts are frequently used in project management as illustrations of a schedule that are used to plan, coordinate, and track specific tasks in a project.
Using Gantt charts you can:
▪ display a histogram
▪ select or clear the elements and values for calculation in the histogram
▪ select or clear the date attributes to reflect the changes in the histogram
▪ display time grid attributes in the histogram
▪ display threshold line in the histogram
▪ select, clear or modify the date in the Gantt chart
▪ display the linked elements and dependency lines between linked elements. To display links, click the element with the outgoing link to display the lines to those elements. If there is more than one link, each link is highlighted on subsequent clicks.
▪ copy chart to the clipboard
▪ generate or print reports from the chart
▪ configure display setting
▪ use a variable time scale density
▪ zoom in and zoom out horizontally to examine the elements and to identify the elements that overlap
▪ sort elements by attribute types in the gantt chart
▪ distribute values over a period of time
▪ display horizontal grid lines.
Note For better performance of charts in Microsoft Internet Explorer 7 and 8, install the Microsoft Silverlight plug-in.
