I was so proud of my crummy workaround for the legend bug not displaying properly on my plot, I had to share it.

text(n(2), 25,'Temp','Color','red','FontSize',9) %place text, choose good spot
text(n(2), 20,'Humidity --','Color','blue','FontSize',9) %place text

%the text below places a rectangle around the text above, this is a very 
%specific location and neither the text nor rectangle will update location 
%if different data is entered, legend for some reason is not functioning
%properly and this is a workaround, manually placing a rectangle in the
%figure window -> right click -> show code will allow you to fix this 
%location with different data if legend is still not functioning properly
annotation('rectangle',...

I was up last night for days trying to figure why my legend wasn't displaying properly when I finally took matters into my own hands!

Glad I found the opengl('save,'software') command fix because this was a bit of work as you can see by the massive novel I wrote explaining how to get your graph to display with a legend properly.

Any idea why the opengl command was necessary at all? I'm guessing it is a known bug.

It seems to be a problem with recent AMD graphics drivers.

Waiting for AMD to fix it.

Ah that makes sense why my old laptop never had this problem.
