David, I agree this is a potential problem, particularly if you are using float rather than double precision. It should be fixed to stop plplot getting stuck in an infinite loop, but to be honest if you are really trying to plot such a small range then rounding errors are likely to occur with al

I think I've found a problem with tick marks and tight ranges. The tick marks seem to be drawn by starting at an initial "tick position" and then repeatedly incrementing the tick position by a delta value until the tick position advances out of range. If the window is setup for a tight y (o
