DPlot

When I import a csv file with some very small numbers (see below), instead of plotting the first column against the second I get a plot of the line number against the first column. I've tried importing the file via drag and drop, as well as just copy-pasting the values. The issue seems to go away if I replace the very small values with 0 and I can certainly keep that in mind for the future, but this seems like very odd behavior. I tried replacing just some of the values with 0, and eventually I can get it to import correctly with a few of these non-zero values but the actual number seems inconsistent. I'm on version 2.3.5.7.

Thanks for the help.

You've run into the limits of double precision (8 byte) floating point numbers. The smallest number that can be represented is ~1.1E-308.

Rather than trying to parse numbers in text files (which would slow the file-reading process to a crawl), DPlot reads those text representations of numbers directly into... well, numbers. So the results in your case will at best be unpredictable. I'm actually surprised it didn't crash.
