Why does this stress-strain diagram have two curves & x-axis scales?

Homework Statement

& which curve goes with which scale? I'm a bit lost

Relevant Equations

I do not understand why you are providing as little information as possible. The graph should have a caption and a description in the text (which should also be named).

Well... it doesn't

Why are you worried about a graph that has no information associated with it?

Lol what type of question is this?
If you're for real -- I was browsing the internet for hw solutions. Came across this problem. The question asks to find the modulus of toughness and resilience.

I'm figuring since the above one has actually shows the curve that i'm used to (yield point, fracture point, & yield utimate)
then the bottom curve should be some sort of Δdeformation.

But it doesn't specificy.

But y'know since i'm student i don't really know. I've only just come to ask people who know more than me. I could ask my tutor but it's Saturday.

There is one curve. It is shown in two parts, one is a zoom in on the first part of the scale. They share the same vertical axis.
Notice how one ends where the other begins, so you know which is low range, starting at zero, and which is the high range.

Oh okay! This makes a lot more sense thank you!

Note that the lower curve is stretched to the right or horizontally only at a scale 80 times respect to the upper curve.
That means that the actual slope would look much steeper than it does.
