Gantt chart with reference vertical lines

Expected chart:



 y-axis: Tasks

x-axis: Dates

Reference lines(more than one): some specific dates


For plotting I'm using custom visual - Gantt (version- from power bi market place which is an open-source visual (code available at Github: ). 


I'm able to plot the duration (start date to end date) of each Task but not able to plot reference lines (which are vertical lines as shown in the graph).

Sample Data:

Any idea of how to achieve the above scenario will be helpful. Thanks in advance.

Gantt has got Milestones bucket to set up vertical lines.
You can look through standard report to figure out how to use them.







I hope this will help to solve your issue.

Hello, @v-evelk  Thanks for your response.

But my milestones(ref's lines) are dependent on Project name and not on Tasks. Those are random dates which I have to plot on the visual. Which will come up as a straight line as shown in my post above.

You are right that milestone records are considered as tasks but task records are just containers for them in this case.

In fact, you can call your milestone records as "ProjectName Milestone [1|2|3]" to show relation with a certain project.
