D3 Scatterplot project: can't pass FCC tests #6 and #8


I’m really confused why my program is not passing tests #6 and #8 for this project. It seems that everything is aligned and set exactly as it should be; all point alignments and ticks are arranged in exactly same way as in the example project, but those tests are not passing.

Could you let me know please what could be an issue?

Here is my project : Scatterplot
