I’m currently learning D3 and am doing the Scatterplot Graph project. I was trying to figure out how to format my y-axis to convert the ticks from seconds to
MM:SS. When reading the D3 documentation, I came up to this page: https://github.com/d3/d3-format#locale_format
I couldn’t quite figure how to use the function so I looked up elsewhere and found this on Stack Overflow: https://stackoverflow.com/a/51975876/688707
Both of these solutions here helped solve my problem, but my question is: How did they know you could use a callback function for
tickFormat? Where do people look for this information?
