Constant lines on dual axis charts

[wynhodgkiss]

Hi,

I have a dual axis chart:

and I'm able to add a constant line against the Y axis but not the secondary Y axis, am I missing something?

I know, I just prefer the format of the constant line. It doesn't add an entry to the legend and you have more control over the format of the label etc

Any idea if there is an existing idea to vote for to have this added? If not, I'll start one myself

I didn't find any idea about the issue, you can suggest here :

According to the legend, you can switch it off and use series labels instead

or generate the legend according to your needs manually like in my suggestion in the linked post :

From the perspective of efficient data visualization, using a graph with 2 y-axes is not considered a best practice. Introducing constant lines further complicates the interpretation for the graph's reader. I recommend creating two separate graphs and arranging them vertically, one below the other.

like in the picture :

Hi @wynhodgkiss 
You don't miss anything.
We don't have it as a functionality of a constant,
But you can create another measure for a second constant and put it on the second Y-axis directly
