X-axis constant line on line chart

[rishtinz]

I have a line chart where I want to place a constant line on x-axis. I can do that when I have the date in x-axis field in Year-Month-Day hierarchy. As soon as i remove year from it I lose the constant line. I want to put the year in the legend instead. Has anyone been able to plot x-axis constant line on line chart with month-Day date hierarchy only?

@rishtinz Create a Month Day column perhaps? Jan 1, Jan 2, Jan 3. Super odd that the x-axis constant line goes away when you take out Year from the hierarchy but stays if you leave Year in and take out Quarter. I tested this and it is indeed the case.

@rishtinz ,

could you share the screenshot of expected output?

Thanks,

Here's the output that I want. As you can see I have Year/Month/Day in the date hierarchy and so the x-axis constant works. I believe it works because its expecting a specific date and as soon as I remove year then the line disappears as well. 

Now that I am thinking, this might not works since the start of the term is never a fixed date but its usually the first monday of the first week of September. 

I wanted to plot a line to indicate a milestone (a date) for a year e.g. the blue line below is the milestone for this year. If I can't do this for multiple years then I guess I need to either label the marker with a different color or the line after the milestone.

I am having a similar issue.  In my case, I am using the x-axis constant to indicate "this week" and shade the past weeks along an x-axis with week numbers.  When I attempt to use a custom date hierarchy to facilitate year-weeknumber along the x-axis (i.e., to extend multiple years), this feature disappears from the analytics options. 

How did you ultimately solve your problem?

Any other suggestions from anyone else?

@rishtinz You could create 2 measures, one that returns data only up to the milestone and one that returns data only after the milestone and thus have 2 different colored lines that appear contiguous.
