Hi @Anonymous ,
We can use UNICHAR to work on it. Here I have created a measure as below.
Measure 4 = IF(SUM('Table'[value])>10,UNICHAR(9650),UNICHAR(128315))
By default, the arrow is black rather than green as we required. There is no green up arrow in Unicode so we’ll need to change the font color of the arrow in Power BI to green.
For more details, please check the pbix as attached.
