I am trying to create a timeline chart by using this extension, which is the one we have available in our company. I add the required five dimensions and even the optional three measures, but the timeline object still shows up as an empty square - it doesn't even load the timeline background.
I have confirmed that the date format for the start and end dates is correct, so that shouldn't be the issue. I have checked this previous thread in which the extension is used, but it gave me no insights on what the issue is.
