Display site name of max figure

[Calb123]

Hi, 

I am in the process of self teaching in Power BI so this is a very basic question but I can't find a video or question on it on here. I have my data input to Power Bi and I have a card on my dashboard of the max reading (Its CO2 monitoring readings) but I cant work out how to display on the card which is the site with the highest reading? 

Any help is much appreciated.

Hi @Calb123 

Is this what you are looking for?

Create a new measure as below:

Site Name Max Reading = CALCULATE(MAX(CO2 Monitoring[Site:]),CO2 Monitoring[Readings - PPM (Parts Per Million)]=MAX(CO2 Monitoring[Readings - PPM (Parts Per Million)]))

Place Measure in your card visual instead of what you have now
