I have a simple dataset that has activities over time. I like to break that down by week so I can see the week to week workload of the team. For some of the activities being tracked in the data there might not be anything so in my line chart it shows as a blank and the line graph breaks. I've looked at "hide empty values" but that connects one point to the next rather than dropping it back down to zero. Is there a beast mode function I can write that would say for for this week, if null (no values time period) then 0 else count however many there actually were? You can see no activity between week 4 and 6 for the red series. no activity between week 7 and 9 on the green series. etc... how to I drop those to zero?
