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.
