Vizlib Gantt Properties - Dimensions, Events, Hierarchies, Tags

Vizlib Gantt supports from one to four Dimensions, which are added and defined in the Dimensions section of the property panel (Figure 1).

TABLE OF CONTENTS


Dimension Settings


The first dimension is defined as an Event, and the subsequent dimensions are defined as Hierarchies. No Metrics are required for Vizlib Gantt. 


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;

Uncheck Include null values (Figure 2) if you need to have null values suppressed in the chart.

In the Representation setting (Figure 3), one Dimension has to be defined as Event and up to three can be added as Hierarchies

Event


Settings for Events (Figure 4) are defined in the properties for the event dimension, and they're shown as bars or milestones in the timeline.


Figure 4: Events


You can set the Start date by using an expression and defining the type.

To set an End Date, you select the End Date type and use an expression (Figure 6).

To set a Duration, select the Duration type and use an expression (Figure 7). 


Figure 7: Duration


You can see an example in Figure 8

Event bars have a Progress Bar option (Figure 9) you can enable to calculate custom progress.

You can then show progress against your target e.g. duration/completion spend/budget (Figure 10).

The property panel also includes an option to show text outside of the event bars in Event Bar Styling if it's required (Figure 11). 


Figure 11: Outside Bars

 

Note: This feature currently has a limitation, as label names displayed outside the event bars will only be partially visible. The full label name can be displayed by using tooltip and hovering the cursor over the label.

Hierarchy


Hierarchy properties are defined in the property panel under the remaining dimensions. In the Groups section, Show group header shows a header bar for groups, using the earliest event start date and latest event end date (Figure 12).

 

Figure 12: Group Header


Under Group header color settings you can enable Auto mode or define a custom colour using the colour palette, selecting to color by Group (Figure 13), Group hierarchy or expression. 


Figure 13: Group Header Color


Show group progress bar calculates group progress bars from the progress bar values shown in each group (Figure 14).

Tags


You can use Tags to add further context to event bars and customer event bars, and you can add them inside or outside the event bar. 


Tag properties are found in the Event Bar Styling menu (Figure 15). 


Figure 15: Tag Properties


Tags can be used to highlight aspects of KPIs within a chart e.g. resource, delays, budget. Figure 16 contains an example where ❌  flags an event as Late
