The sliders were helpful, and you explained things very well. I also like that you made a chart with each different concept so I could easily see all of them. :-D
Hello, you should be able to click on the x-axis and then get options, one of them lets you choose the unit for the axis. But I fixed that for you, so everything should be exactly as it was in the video right now, try reloading the page and let me know if it works :)
