Vizlib Gantt - Data Elements

Dimensions


The Vizlib Gantt supports from one to four dimensions. The data section permits you to add dimensions and define their settings. The first dimension is an event, subsequent dimensions are Hierarchies.



Why not try our sample load script below:

Transactions:
Load
(today() - (rand()*200)) as Date,
(today() - (rand()*200)) as StartDate,
(today() - (rand()*200)) as EndDate,
'Event ' & mod(TransID,26)+1 as Event,
Pick(Ceil(3*Rand1),'A','B','C') as ParentGroup,
Pick(Ceil(6*Rand1),'a','b','c','d','e','f') as Group,
Pick(Ceil(3*Rand()),'X','Y','Z') as SubGroup;

Load
Rand() as Rand1,
IterNo() as TransLineID,
RecNo() as TransID
Autogenerate 4000
While Rand()<=0.5 or IterNo()=1;





Note! No Metrics are required for Vizlib Gantt. 







Dimension Settings



  • Include null values 


Uncheck this box to have null values suppressed in the chart.



Representation

One of the Dimensions has to be defined as Event and up to three can be added as Hierarchies

Events appear as bars or milestones in the timeline. Milestones and events are dynamic and change with your data.

Hierarchies help to organise the event bars on the timeline, up to 3 groups can be added.


For Events

Set the Start date field by using expression and define the type
For End date- set the End date field using expression. for Duration - the Duration field.

example




The event bars have a progress bar option that lets users calculate custom progress based on duration/completion spend/budget etc





Hierarchy

Group Header
Shows a header bar for groups, using the earliest event start date and latest event end date.


Group Header Color 
Enable Auto mode or define a custom colour using the colour palette or standard expression.

 
Group Progress Bar 
Calculates group progress bars from the progress bar values shown in each group.
