Describe your problem and - if possible - how to reproduce it

In this sentence, the emphasized "then" should be "than".

In this example, the curve moves faster through the Y-axis (starts at 0, goes to p1 y value of 0, then goes to p2 y value of 1) then it moves through the X-axis (0 to start, then 0 for p1, up to 0.58 for p2).
