Highlight max value in column chart

Hey,

I created this measure:

Measure = 
var allthedatesused = ALLSELECTED('simple table'[some kind of date])
var themaxvalue = MAXX(allthedatesused, CALCULATE(SUM('simple table'[quantity])))
return
IF(sum('simple table'[quantity]) = themaxvalue,"#ff6600")

Then I assigned this measure to the data color (mark the chart, and select formatting window) advanced controls (formerly known as conditional formatting)

and chose this setting:

After that my sample chart will look like this:

If this is not what you are looking for

please provide a pbix with some sample data, upload the pbix to onedrive or dropbox and share the link.

Regards,
Tom

TomMartens Awesome, thanks! It worked a treat. It seems to only work when using a column with date format and I'm trying to display axis like you have on the chart MMM YYYY or MMM YY. Do you know how I can do this?
