Gannt Chart with single line for all project phases

[SM370]

Hi everyone,

I am a new user to Power Bi and I am hoping the community may be able to help me with my problem. 

In Power Bi I want to create a dashboard that will contain a gantt view of my projects refecltive of all the different stages/phases within the lifecycle in one line across the time horizon. 

My data table has the follwoing columns;

TaskID	TaskName	ParentTask	TaskStart	TaskEnd	RAG	Assignee
1	Project 1		01-Aug-23	27-May-24	Green	joe Bloggs
2	Project 2		01-Aug-23	27-May-24	Green	joe Bloggs
9	Project Charter	1	31-Aug-23	26-Jun-24	Green	joe Bloggs
10	Scope and Analysis	1	30-Sep-23	26-Jul-24	Green	joe Bloggs
11	Requirements	1	30-Oct-23	25-Aug-24	Green	joe Bloggs
12	Development	1	29-Nov-23	24-Sep-24	Green	joe Bloggs
13	Testing	1	29-Dec-23	24-Oct-24	Green	joe Bloggs
14	Implementation	1	28-Jan-24	23-Nov-24	Green	joe Bloggs
15	Project Charter	2	31-Aug-23	26-Jun-24	Green	joe Bloggs
16	Scope and Analysis	2	30-Sep-23	26-Jul-24	Green	joe Bloggs
17	Requirements	2	30-Oct-23	25-Aug-24	Green	joe Bloggs
18	Development	2	29-Nov-23	24-Sep-24	Green	joe Bloggs
19	Testing	2	29-Dec-23	24-Oct-24	Green	joe Bloggs

I am using the PowerGannt chart visualisation which now looks like this

I would like there tow items on the left (Y axsis) Project 1 and Project 2 and all the different phases reflected on the x axis. 

How should I go about this? 

I have tried to incoorpate a heirachy between task id and parent task but this didnt change the end result. 

Thank you in advance for your assistance on this.

Hi @SM370 

​To get all your project phases to appear on a single line horizontally, you need to utilize the Parent field in your Gantt visual to create a hierarchy.

​Steps to fix:

1. ​Field Mapping: In your Visual Fields pane, ensure ParentTask is placed in the Parent bucket and TaskName is in the Task Name/Item bucket.
2. ​Format Settings: Go to the Format Pane > Chart Settings and look for a toggle called "Roll up tasks to parent" or "Display sub-tasks in parent row."
3. ​Legend Hack: If you want different colors for each phase (e.g., Testing = Blue, Requirements = Green) on that same line, drag TaskName into the Legend bucket as well.

​This will collapse the phases into the Project 1 and Project 2 rows while keeping the timeline distribution intact.

​If this resolves your visual layout, please mark this as an "Accepted Solution"!

Best regards,

Hi! @SM370 

As @vaibhavmahajan mentioned this won't work because of limitation of that visual you can use Deneb or
xViz Advanced Gantt for your scenario.

Hi @SM370 

If the client allows certified visuals → Deneb (best option)

Use a custom visual instead of Gantt
Best options:

Deneb (Free) ⭐⭐⭐⭐⭐

Deneb gives you:
One row per project

Multiple colored segments (phases)

Exact control over layout

This is the only way to truly draw:

Project 1 → Phase1 → Phase2 → Phase3 → Phase4 
Project 2 → Phase1 → Phase2 → Phase3 → Phase4
