Chart missing client name as legends

Hello

I am having issues charting 3 metrics in a scatter chart for our dashboard.

Customer Name - Units required - Year commencing.

My units [MV] are vertical, [COD Start] is horizontal BUT my customer name [Primary Row] is not showing as legends. The plotting is correct and this is how i want to vizualise the data.

Any helps would be great appreciated

Many thanks
