Scatter plot project ,tests not passing but dots look correct?

Sorry, I’m just more confused.

I timeparsed all json d.Time and d.Year values(to create date objects) and so those can not be passed ,as is, to the scales , as in xScale(d.Year) ?

I looked at this site on how to create scatter plots :
simple scatter plot

So if he does it like that , why is mine wrong? I just want to understand otherwise it’s all pointless . Hope someone is willing to answer .

Also , why is this same project correct , even though the dots aren’t aligned the same as in the FCC example and his axes are different:
other freecodecamp coders’ project

I made sure my chart looks the same as the FCC example , yet it’s wrong?
Hope I don’t sound whiny, I don’t mean too , I’m just confused and maybe slightly annoyed. :stuck_out_tongue:
Thanks :slight_smile:
