I have a salesforce import and am pulling in records that are not created every day. But I'm trying to trend this information and its difficult to do since the last time a case of this type in salesforce was created was several weeks ago. So on my card, it looks as if domo hasn't updated since then, but really non cases in salesforce have been created. I'd like to fill that gap with zeros but I'm having trouble figuring a way to do so.

So really I'd like to fill the gap here with zero values by week but also would like to see zero values until the next time we have a case created for this type.
Any thoughts?
