It is hard to say what the problem might be because you have 
not shown the plot command itself.  What are you plotting?

It works fine here, but I am probably testing a different plot command.
Please show the entire series of commands that result in an
error message.

There was no intentional change in the effect of command
"set autoscale xfixmax".     If there is a bug that caused an
unintentional change we can try to fix it, but you will have to
show an example of the bug so that it can be reproduced.
