    Is a bar graph with a break in the vertcial axis a limitation?

    Is a graph with an axis break a limitation?

    Here is an example problem.


    A The bars are different heights.
    B Not Here
    C The vertical axis has a break, so the bars are not proportional
    D The bars are different widths.

    Would it be B or C??

    That break means from 0 to 110 it isn't a constant change like from 110 to 260.

    We go from 0 to 110 in one bar movement and then each bar jumps up 30 units per bar.

    I know that. I'm just asking if an axis break makes a graph misleading.

    Why would it be misleading?

    The break tell us something so we aren't been deceived.
