Error: import dmslogo

Dear Dr. Bloom,

Thanks for your works in DMS. I faced errors while importing dmslogo.

@yeli7068, this should be fixed in the newest version 0.6.3. Let me know if the fix didn't work. At least for me, this error only shows up on Mac and not Linux so a bit hard to diagnose.

Merry Christmas and Happy New Year, Dr. Bloom!

What a coincidence that I am using Mac.

I am going to try the new version. Before that, I fixed this issue by installing the matplotlib=3.2.1.

Another issue is regarding the line plot. I am applying dms_logo to high_antibody_results.csv. It was a little bit weird about drawing the line plot with error: x_col not sequential unbroken integers. Even after reading the instruction, I still felt confused especially there was a gap between original and new in BG505_to_HXB2.csv (e.g. original: 141, 142, new:142, 151).

I don't quite understand above problem. Can you open a new issue describing it in detail: the exact code you are running and the resulting error?
