Setting the y-axes to have the mm:ss format?

Curriculum Help

Hi all

I am having lots of trouble setting the y-axes to have the mm:ss format.

The FCC example code shows a way which I try to replicate but it simply does not work on my code for some reason (line 54)

What could I try?

Thanks for your time

Jaime

Solved it, just needed this line:

const yAxis = d3.axisLeft(yScale).tickFormat(d3.format('d'));
