I made a Bar Chart using "Year" as a dimension. So far, the chart shows me two bars, one for 2017 and another one for 2018, totaling 300 for 2017 and 1500 for 2018. So far, so good! Pic for reference:
The problem is that I use Month as a button filter, and can't make it work as intended, which is the bar chart showing the Cumulative sum up to the selected month for both years displayed. It only displays the results for the selected month.
