I have a dataset which i am using for learning. It is fruit production for UK, France, and Spain, from 2014-2018. I am focusing on UK, on the fruit “Pears”. I have a chart which i want to show the percentage difference for each year in production of Pears.
It looks like this:
It is quite simple, but i want to colour anything above 0% green, and anything below 0% red. So it colours whether it was a positive or negative difference.
The only problem is that i can’t use a calculated field i have created to group them.
The Year field is just 2014-2018, but the value% is the weight of fruits (in this case pears), but as a percentage. I have used 2014 as a baseline, so the calculated field was:
(sum(Value) / 25880) - 1
this is dividing 2014 pears value (25,880 tonnes) by itself = 1, -1, then i turn this into a percentage in my chart. The others will then use the same calculation, to determine whether it was an increase or decrease from 2014. I just want a way to colour the decrease in red, and the increase in greed.
I tried using this field to group them, which would work, however i can’t use aggregated fields in the group dimension?
