Yeah, I am probably just overthinking it, sorry. I would show percentage change as +10, 0, -10

And nothing, sorry if i implied anything. I just wanted to point it out. I appologise. This was my first comment on lemmy.

I don’t care too much for my personal view because I think I can read the chart well. I met several people in my life that would misunderstand a chart if it would not show the axis starting at 0. I don’t consider the space a waste. I consider it an indication that the shown value is less of an effect than it would indicate if the chart is zoomed in.

To be completely honest, I just wanted to test that commenting on a thread on other lemmy instance from my new lemmy instance works.

Note the vertical axis does not start at 0.
