The ability to provide specify the Data Colour for each item in the Legend field. E.g. a column from the data source in which to specify the colour e.g. #A66999 for each item in the Legend field. This would apply to all the standard charts, e.g. bar, column, line chart, any of the charts with the Legend property.
When I read this article https://powerbi.microsoft.com/en-us/documentation/powerbi-service-tips-and-tricks-for-color-formatting/#use-diverging-color-scales I tought that I can do whatever I want with values, I have a customer that need this feature please consider it for the next releases.
This is really important for us!... having to manually update chart colors for each category on every new pbix is extremely tedious - we have standardized colors at our company, and this feature seems so basic - the competitors have it! It would also really help the adoption of the tool....
Manual color updates are very important. Don't have to hover for tool tip values. Specially, for the dashboard view. One cant moves cursor on all the tiles rather can analysis data with just color patterns.
