Is there any way to either hide a point in a graph, or lock it from being dragged?
If you want to hide a point, you can click on the colorful dot to the left of the expression. The color will turn off, meaning the point is now hidden.
If the coordinates are variables, the point will be movable. If you long press on the colorful dot, a menu will pop up. One of the options is to turn off the ability to drag the point.
@cwinske is definitely correct on the best way to do those two things.

Yey. Worked out a way of achieving what I want.
