Hi guys,

As in the title, is there any way to add two reference lines, one verticle and one horizontal in a DOMO line chart? The solution can be DDX or the default line chart.

From that, is there any way to add the third horizontal… if there are ways…

Thanks,

Long

    I don't know about the default line chart. But I can do it in a brick.

    Thank you very much, Arbor.

    Apologize first for this following basic question, but do you know how to do it using the Phoenix brick template?

    Apologize for the confusion. I was referring to Domo’s native library. I captured this in the DOMO appstore:
