      Description

      This bug is quite simple. Create a line series where the numbers are sufficiently small, and it won't get rendered. I've found that anything <= 1e-14 will cause this to happen. Using the same exact code with larger numbers will render the line series perfectly.

      I've also noticed that sometimes any axes with these small numbers will now show up at all, but this doesn't consistently happen (e.g. the x values are the super small numbers, and the x axis doesn't show up but the y axis does).

      I've encountered this bug using both linear axes and log axes.
