Hey, I would like to report a bug with isolines. Screenshot here. Firefox (v57.0.2) and Chrome (63.0.3239.84, 64bit version) report different warnings which are in my opinion irrelevant to the bug. OS: Windows 7 64bit.
Hello Flea, thank You for the bug report. We already know about the bug and we're currently working on it. I'll let You know when the fix is released.
