Hi @Anonymous ,
It is not supported to sort Tooltip in Power BI Desktop currently .There is an idea about this issue, please vote it up,
https://ideas.powerbi.com/forums/265200-power-bi-ideas/suggestions/20067754-legend , to improve the Power BI Desktop.
It is a place for customers provide feedback about Microsoft Office products . What’s more, if a feedback is high voted there by other customers, it will be promising that Microsoft Product Team will take it into consideration when designing the next version in the future.
We also submitted this feedback to the product group internally, so that the product group can pay attention to this problem and speed up the issue repairing.
Best Regards,
Amy
