Sometimes, I'd like to give an upper/lower error as absolute value instead of relative to the x/y value. For example, use Avg(...) as x/y coordinates and Min(...) as lower, Max(...) as upper error. This requires to use Max(...)-Avg(...) and Avg(...)-Min(...) for the Error Bars. Just using Min(...) and Max(...) would be nice. Granted, this is not a big issue, but it would be a nice option.
