In pie chart legend is not visbilein in web :
In Desktop it is visible like this:
I have tryied publish with diffrent setings but problem still ocures. Some time i was able to get it correct but after so me time or data update it become again blank.
I cannot reproduce the issue. Try the latest version of Power BI Desktop and check Supported browsers.
Thank you for response @v-chuncz-msft
I have already try to update to nevest version Power BI Desktop and it didin't work. It looks the same in 2 browsers. Any other idea?
Any other visualization done in web give the same effect. This column have lost data, it is empty. Is possible that table relation/definition can couse such strange behaviour?
