Running Total - Count Groups with Missing Values
I'm trying to create a running total for the number of open data sets our department has published by month, so that we can see how many data sets each division has published through any given month. There are months where only one division published an open data set, and months where no data sets were published at all. Here's my data:
What I ultimately want is a simple graph like this:
But using this formula:
I get this instead: In a matrix & a bar graph.
I think what I need is for the matrix values to fill in the prior value when there is no new data, instead of returning a blank. I can't for the life of me figure out how to do this.
So in summary, I'm looking to:
- Create a running count of rows
- Where months that have missing data are still pulling the totals from prior months
- And where each month is stacking / categorizing my values by group = division.
Any help would be much appreciated!

Firstly, create a date table in Power BI Desktop following the guide in this blog.
Secondly, create relationship using date field of the date table and pub_date field of Open Data table.
Thirdly, create measure using DAX below.Running OD = CALCULATE(COUNT('Open Data'[ds_name]),FILTER(ALL('Date'),'Date'[DateKey]<=MAX('Date'[DateKey])))
At last, drag date field of date table to X-Axis of your chart.

Your solution was so helpful! See below for the viz I was able to create. As you can see I've made a combination bar & line chart. I just have one more question:
How can I get the bars to stop appearing after today's date, while the line continues? I want to be able to see the goal into future months without seeing the actual progress made. Is there a way to apply the "Today()" function to the running total calculation, so that the calculation only shows the running total up to today's date, and doesn't project out into the future?
