Is it possible to create a custom a display format?

[Martin Mattsson]

I would like to customize a display format so that it displays the number with three decimal points if the number is below 1 (with leading zero), two decimal points if the number is between 1 and 10, one decimal point if the number is between 10 and 100, and without any decimal points if the number is above 100. I would like it to insert commas to make larger numbers more readable but I would never like it to use the exponential format. Is there any way to achieve this with the %gc and %fc formats? Or is it possible to create a custom format that achieves this?

I don't believe this is generally possible. You could do it on the fly for graph axis labels. If the number of values is not too large, you could get as far as you could through value labels. Or you could define a string variable following your rules. None of these is a universal solution.
