When I build grouped bar charts, I'm created a 2015 v 2016 series to split values. In some cards, 2015 comes before 2016 and in others, 2016 comes before 2015. How can I ensure they are consistently in the same order?
have you tried adding the field that contains the year values as a second sort? So if you look at the Sorting area in Edit mode, you should have two fields in the Sort area Month and Year.
are you sorting the charts using the field has the year values?
They are sorted by month and split into a grouped bar. One bar is for 2015 and the other is 2016.
